1998 Ford Explorer Sport
So, my engine light came on, I went to AutoZone, and they told me it was a P0452. (98 sport SOHC) However, the part that they brought up was a fuel pressure thing, which then took them to a "nonservicable" fuel filter, which they then couldn't look up. Tomorrow I'm giving the printout to my mechanic friend so he can have the code, and I'll be asking him to fix the car, is there anything I may want to tell him since AutoZone was basically "I dunno lol have fun"?

(Haha, It's refreshing to know it isn't that damn O2 sensor again but I'm not sure I like the "Severe internal engine damage" warning on this AutoZone printout)

For some information, you can google "PO452 Ford Explorer".

Just a thought. Good luck!
 






P0452 - Faulty Evaporative Emission System (EVAP) Pressure sensor - Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted - Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection

It's emissions related and nothing that prevents you from driving your truck. It has no effect on the engine. By all means look into getting it fixed, but don't throw parts at something that could just be a broken wire or a bad connection. ODB II codes are mostly all emissions related and only point you in a direction as to where the problem exists. Never buy parts just because of the ODB code description.
 






Yes Koda if you remember the stinking mice chewed the harness connector off at my canister. Scoundrels didn't even leave enough slack to solder to, I had to rebuild the connector.

Ok, good, that means it won't blow up haha, and yeah I didn't buy anything. I'll probably take it down to my friend on Monday so he can try fixing it. (also... why do you guys call them trucks? Heh, just curious)
 






That's what it says on the title. Ford Truck Explorer.

Yes,I do recall that. Squirrels do even more damage.

Would you prefer SUV? Body on frame = truck to me. They certainly aren't cars.

The pack rats we had in Missouri were the damnedest thing I had ever seen! Chewed completely through a battery cable! But the most amazing were the mummified mice I found in my clutch housing, '96 F-150 5-speed manual. Clutch started slipping in 5th. gear, OK in 4th, figured disc all but worn out. Started wondering when I pulled starter motor, and saw a dried-up corpse, reached in, 3 more, but WTH would they have done to cause clutch slippage? They got in through the two vent holes seen on the back:

Long strands of Johnson Grass had wound itself up into a thick "rope", around the pressure plate release fingers, and lodged between them and the plate itself, where they rest against it when clutch engaged, partially releasing pressure from disc! Couldn't find the pic, will look again. I just couldn't believe it! imp

Found it: The disc was barely completely worn-in, 92,000 miles. PP just fine. Too bad, I bought a new clutch ass'y before I opened it up! Holes got window-screen covers, silicone-rubber glued on.

Wow! Just wow. Who'd a thunk it?
 






Yea, my exploder's been going around just fine for me with that light on, and you're right, heh, I guess it's a lot more like a truck than an SUV. Sure does bounce around like one! So, I'm gonna go ahead and let my friend fix it, I won't worry about it much but I'm gonna make sure it's fixed so that if something else happens I'll know. And jeez, those are some suicidal mice! What did they think they would accomplish squeezing in there!? Sure, the snow and ice and salt is hell up here in the mountains but at least I don't gotta worry about Mice in weird places! (Just those darn stinkbugs... one day I parked at work and I got buzzed by one and freaked out, if it had done that on the highway a minute earlier I would have crashed!)

Now... this is more nitpicking, but do you think I may be pushing the poor thing too hard? Ya know, going 80 mph up a mountain at around 4000 rpm, or taking bumps a little too fast? I mean, I know it can handle it, but I don't want to shorten the life of things drastically if I can avoid it by just being more gentle with it... Hah, I already introduced the driver's side front wheel to a highway median at high speed a month or two ago, I'm super impressed at how well it took that hit, if I had inherited our family's nasty old minivan I would have smashed in its front bumper driving that way.

Sorry about the rambling, I'm last-minute working on an essay, and here I am avoiding it at any cost for some dumb reason. Why do I have time to type all of this but not a paper!? why!?
 






From your description of how you drive, I'd say you are pushing it too hard. After all it's a 19 year old vehicle, with quite a few miles on it, with an unknown service history. I tell my family members to take it easy on their trucks for the same reason, even though I keep up with the service and repairs, they all have near or over 200,000 miles on them. If you beat on it you'll most certainly shorten it's life. Another reason to take it easy is that these trucks have a history of rolling over, with their high center of gravity. Rolling it over will not only destroy your ride, it may kill you.

It was pretty unreal. When we first moved there, we saw many parked vehicles with their hoods propped open a foot or so. After the rats built multiple nests under the hood of my '71 F-150, destroyed the wiring, even chewed ignition wires, I learned that it was believed the open hoods discouraged the rats.

My Explorer, parked 2 days not driven, we got nearly to town, 20 miles, she started misfiring. I pulled over, opened hood, and the rubber nipples on several wires at the coil were ON FIRE! A small pile of sticks, leaves, etc., was nestled not far away. I had caught the fire just in time, put it out, found the trouble: rat had chewed completely through one of the plug wires close to the coil, leaving it hanging by threads of outside insulation, but the center conductor had a gap: enough to keep sparking until it caught the insulation on fire, then the ends parted, and started the misfiring.

I been around the block way more times than imaginable! imp
 






As an actual teenager, there's no way I'd go 80 in these things, or hit medians at a high speed, because they will roll right over, been there, done that at lower speeds, these are extremely top heavy, more so than a truck since trucks are wider generally. The bumps will eat ball joints, and that many RPMs will drink gas, besides that things have aged, and my 01 doesn't see speeds over 65 for multiple reasons. I've thought about other vehicles for that reason, but elected to just put offset wheels and wide tires on it soon.
 






Hmm, I think I'll listen to the nice 70 mph speed limit and stop racing down the fast lane, eh? And boy, with my 460 pound ass up in that front seat it's probably more likely to roll over. And yeah, I'm surprised the hit to the median didn't flip the poor thing. Jeez, now I feel bad for pushing it all the time, learning to drive in our silver beater of a van I followed the speed limit like I was gonna get candy for doing it. Also, I've read over a few different... arguments on here about tire pressure but I might as well ask, 35 is fine, right? I'm not doing no 26 and though my tires say they can do 44 I wouldn't ever hit their Max, so I went with 35 whenever I filled them a month or so ago.

Now, about rollovers... This will be hard to describe but the hill I live on is very steep, and you have to get into our driveway through a sort of ditch while either coming down or up the hill. So I guess what I'm trying to ask is, how far a certain way into a tilt can I go before it'll fall over? I wanna make sure I'm okay when I inevitably have to gun my way up the hill in order to get into the driveway, cause once we're into winter the road basically turns into a big ice slide. Haha, I've already had to use 4 wheel drive once already in order to back into the driveway, cause they had no traction trying to back up the small grade at the mouth of the way.

If it helps, here's a picture of it from google images in like, 2008 or 9. This picture is looking Up the hill, so you can see how steep it is. Now, imagine almost a decade of rain and ice and snow, because the road and that black thing have a pretty big rain channel between them at this point, and there's always a big mount of packed snow/ice there every year. basically... the whole road turns into packed snow. It's old, and curved, so the snowplow can only get the center of it. (haha I remember one year a car slid down onto a pile of snow and got stuck on that rock next to the mailbox, I think someone with a truck had to pull them off of it, that's how high the snow eventually gets) Anyway.... I don't know where I was going with this, it's 4:30 am, but after all the effort it took to type this I'll go ahead and leave it in I guess: http://puu.sh/sLxYR/b347541dd6.jpg
 






Typically people roll Explorer's at speed because they do abrupt maneuvers and upset the suspension. Low tire pressure and bad shocks make the situation much worse, but the vehicles have a very high center of gravity and a relatively narrow track. I find that sticking to the speed limits and not exceeding 65 on the highway keeps my pucker factor to a minimum. I keep my tires at 32 PSI to have adequate pressure and a reasonably comfortable ride. Newer drivers/young people's biggest reason for flipping vehicles is because they get a wheel off the right side of the road and turn the steering wheel to far to the left trying to get back on the pavement. All of a sudden the tire grips, hops back up on the pavement and the vehicle makes a sharp turn to the left. My youngest daughter managed to flip her first car that way (a Pontiac Sunbird, which is pretty hard to flip compared to an SUV). In case you've never experienced this, the answer is to slow down until the wheel can climb back onto the road w/out having to excessively turn the steering wheel.

Read the stickers on your visor and take heed. BTW, the 26 PSI recommended tire pressure sticker was a mistake and probably the main reason so many Explorer's flipped over years ago, due to tire failure. Most people don't pay attention to their tire pressure, so when you start off with under-inflated tires and then let them get another 10 PSI lower you're in big trouble. Don't forget that a tire with 35 PSI in the middle of summer, when its 95 degrees, will drop pressure quite a bit when it's 25 degrees out. With you weight, you're probably more likely to flip onto your left side than your right.

I rode motorcycles w/out killing myself for 40 years and learned to really concentrate on my driving (and other peoples driving). I think the lessons I learned motorcycling have helped me keep safe in 4-wheeled vehicles. I've also been driving SUV's since the early eighties, so I don't drive them like sports cars. With today's "distracted drivers" I've given up motorcycling, but I still keep a close eye on other drivers. When driving, be prepared and ALWAYS leave yourself an out (best driving advice I ever got).
 






35 will be fine, I run 35 on mine and rotate every oil change and I have good tire wear. I also keep good shocks on there, if you have the factory shocks like my 01 had, you'll do great to get some new ones. I snagged a used set of KYB shocks a while ago for my 01 off someone's lifted 99 that was junked over no oil changes, and the ride improved greatly. My 01 when I got it felt like bumps threw it all over the road.

@koda2000 "My youngest daughter managed to flip her first car that way"

Luckily it was not a Corvair! They took several of the world's foremost race drivers, I think Andretti was among them, cut wheels at speed, and not a single one could stop the oversteer sucking the inside wheel and tucking it under, flipping the car. Saw a video of it happening once, real interesting. Ralph Nader went nuts berating the car, making a name for himself. My co-worker bought one new, nice 4-speed model, guy cut him off on an exit ramp, cut the wheel, there she went! We all knew of the cars' propensity when he bought it. "Never happen to me". They were neat little cars, economical, fun to drive, would go up Prince's driveway proly pretty well, air-cooled rear engine, almost a take-off on Preston Tucker's Tucker Torpedo. imp

EDIT: "When driving, be prepared and ALWAYS leave yourself an out (best driving advice I ever got)."

In our area, with a great proportion of the drivers retired elderly old farts living here (like me), and much of the rest crazy tourists from CA, rear end collisions are a fact of life. They have no clue that if the driver ahead taps his brakes, it's a given: you're into him.
