- 2003 Explorer XLT 4.6L
I recently picked up this 03 Explorer with the 4.6L in it, the odometer says roughly 198k. I bought it pretty cheap so I've been fixing things and sorting out the bugs. Up until now the fixing has all been mechanical, bearing assy's, upper control arms, latches, hinges, etc.
Here's the deal, check engine light was on when I got it and I don't remember the exact code it gave but I remember it was both upstream O2 sensors so I bought and replaced both. Prior to replacing them it seemed to run well enough while occasionally running a little rough for a few minutes while cold. Now that I've replaced both upstream O2 sensors it runs like absolute sh*t and has a pretty bad misfire and won't go down the road without popping and banging. I read that the common issues related to the O2 sensors are burned/chaffed wires and fuse #41. Checked the fuse, it was good. Checked the wires, both were good at least up to the connector from the sensor. The old sensors were NTK and didn't look to be that old, or even bad.
The codes I got last time I checked were as follows:
P2196 O2 Sensor Signal Stuck Lean - Bank #1, Sensor #1
P2198 O2 Sensor Signal Stuck Rich - Bank #2, Sensor #1
P0135 HO2SHTR11 Heater Circuit Error
P0053 HO2S11 Heater Resistance Beyond Limits
P0059 HO2S Heater Resistance - Bank 2 Sensor 1
After checking the fuse and looking at the wiring today I ran it again. It ran fine for the first 10-15 seconds and then ran like dog sh*t again. Then after about a minute it cleared up and ran perfect. I cleared the codes and then it started running like crap again. I checked the codes and now it is only giving me "P0135 HO2SHTR11 Heater Circuit Error", though I've only let it run for a couple minutes after clearing the codes so the rest might show up later.
Immediately after typing this I'm going to get in there and see what the wires look like from connector to harness but I'm not very hopeful because, as far as I could tell, the plastic wire loom was still intact after the electrical connector. This is supposed to be my daily so I NEED this to be fixed ASAP so anything you guys can give me that will help me get this going would be very much appreciated!
