HO2 sensor/maf or vaf/ crank shaft sensor
Hey all, I have this thread on Zr2usa.com, carolinaoffroad.com, and tried everything they have said on top of everything else I could find and look up.
Mods: I put it here since its a broad range of items that are wrong and I need everything fixed before 8 a.m monday.
I have a 2003 s10, my inspection is due 1/15/2010. I thought I had it all figured out till:
P0141 - HO2S Heater Circuit Bank 1 Sensor 2(also malfuntion)
I replaced my Bank 1 sensor 2 o2, didnt fix my problem, replaced pass. side y pipe o2... didnt fix it...(for free)
A guy told me it was my cat... but that will come later if I cant fix it in the wires. I have 11.3 V and i have .4 or something omhs(sp?)
I have tried both sensors to both locations, re-placed fuse (its getting power)
Head lights: I was running projector light for a bit, the pass. side went out. i took them out to work on them and replaced with the stock. Neither bright or running lights come on, on the pass. side and they are getting power.. 12.6 to everything.
Update: tonight we cut into the ground wire to ground the running bulb. We put it on to ground and it still was searching for ground, my whole pass. side is searching for ground and I tried the ground under air box, and ground under the tray only goes to the battery.
o2 has power and we are thinking it is a ground problem and tommorrow im going to back prob them and see if im losing anything from the connecters.
Also forgot to add, but we un-plugged the pcm (pass side kick panel, and positive battery cable) to reset and the ses light came back on.
Update: We checked battery grounds, grounds for fuse box, swapped around my fuses.... still nothing,
I bought a obdII reader for 150...
Also i rode for a good 10 miles and came home and check and the only things im throwing is
maf or vaf low circut and Crank sensor... something.
All this with out my pass. side running light.
Jordan is still very confused. Any ideas, or if your in my area and can lend a hand, please let me know.
Thank you for reading, and helping in advance.
