holy mother of CEL codes!

[bmacd]

Was driving from my work to another location today only to be hit with some new CEL codes:

P0084
B0490
B1080

And I've been driving around with these codes on for the last year:

P0141
P0306
C0041

Any advice? I wrote down all the codes before I cleared them, and after I cleared it, only the second grouping of codes appeared again. The car felt like it was starving for fuel, with a horrible idle and stuttering except when mashing the gas.

The B and C codes are not powertrain related. B stands for Body Controls and C stands for Chassis codes. Anyway, the P0141 is a heater problem in your bank 1 sensor 2 O2 sensor. The code P0306 is a misfire on #6 cylinder. You need to see what your computer is doing, if it's adding fuel or taking away or what. Look at your fuel trims. Basically the heater in the 02 sensor is to allow the computer to get to Closed loop earlier which inturn gets better gas mileage and better emissions.

based on my gas mileage, i'd say i'm running rich. In the morning warm up before work, the exhaust fumes smell foul of gas. Forgive my ignorance, but what exactly ARE body and chassis codes and what do they mean to me?

Was the misfire a fluke? It went away after I restarted the car. Sounds like I may have a worse Michigan winter than I planned on...

thanks in advance

BMACD, the C0041 is related to the "Right front wheel speed sensor circuit - out of range". It's the ABS sensor. They are magnetized and pick up all sorts of metallic junk, and sometimes can be cleaned.

Don't know about the B codes.....maybe check all the exterior light bulbs....?

A new wire and/or plug should cure the #6 misfire. The B1S2 O2 code is probably a bad sensor.

I looked these up and found...

B0490 = Passenger Temperature Control “Cooler” Switch Stuck Range
B1080 = No matching code

 

[ExplorerDMB]

right - body codes are just like climate control, rear air, defrost stuff. Nothing really to worry about, a B code shouldn't throw the MIL.

Ahhh....even more codes. I have to stop procrastinating and fix this thing! It feels like it's running on two cylinders now and my gas mileage is right around 7mpg. I have literally zero acceleration. I'd probably be more inclined to fix this sooner if I didn't work about five minutes away from my house. Unfortunately, my new girlfriend lives an hour away by my parent's house, so I'm paying up the ass for gas.

Here are is the latest reading from my ScanGuage:

P0174 system too lean (on fuel, I assume)
P0305 cyl #5 Misfire detected
P0306 cyl #6 Misfire detected

B0084
B00D0
B1C80
B0005
B009C
B01A4

P0030 Ho2S Heater Control Circuit (Bank 1, Sensor 1)
P2240
B124E

Help!!!!

How long has it been since you had new spark plugs and wires? If it's been over 70 or 80,000 miles I would probably start with new plugs and wires and see if it clears up the two cylinder misfire codes.

I'm such a piece of crap...I have a brand new set of Motorcraft wires and autolite plugs in my garage. I'm pleading ignorance on not knowing how to replace them. I have a garage I can pull my truck into, but I've read so many horror stories and not being able to change the plugs tucked in the rear.

They are very easy on the v-8
harder on sohc
hardest on ohv 4.0

Jack up and remove front wheels, remove the floppy black thing in wheel well, you can now change plugs in about 1/2 hour max.

 

[ExplorerDMB]

Easy on the 8? I think it's easier onthe SOHC.

I just thought I'd update my post. I had my plugs and wires changed @ Auto Lab ($140), and all of my trouble codes went away initally. My explorer is running like a top!

After two days, the following codes appeared:
P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0800 ?????? <---not sure what that is

Thanks,

Bill

Sounds like the heating element for the O2 sensor is bad, probably needs to be replaced. It is usually best to replace them all at once, but if your budget can't allow that, at least do the two front O2 sensors at the same time. As for the P0800 code, I can't seem to find that code online nor does my Palm scanner have that code listed either.

 

[bmacd]

Is the heating element part of the o2 sensor or is it a seperate part?

 

[ma96782]

You could just swap them: left to right (as a test). If the code jumps to the other bank......it's the sensor.....at that point, just replace it.

Or....

IF, you're going back to that shop that did your wires??? Just let them worry about it.

It's part of it.
