doesnlt help me at all. my system has single exhaust and only 2 sensors and i still hae no idea how to test and repair the wiring or even where to begin to try to find out !
Bill Huff what make and model is your vehicle and what error code do you get?
I have a 1997 Suburban and spent about an hour running back and forth between the computer and the car but I found at least the sensor being called out by my P0141 code. It is located just behind the driver side front wheel. If you run your hand along the exhaust from the front of the engine back toward the rear you will see the sensor sticking out clearly. I looked at the passenger side and it is in a similar location. Right on the pipe, just behind the wheel.
Should have O2 sensors bank 1 sensor 1 by the exhaust manifold around cylinder 1 on driver side bank 1 sensor 2 near the cat behind I believe. Bank 2 sensor 1 near cylinder 4 by passenger side exhaust manifold and bank 2 sensor 2 towards the cat
it helps a lot....
Thank you...Arnie V.
not a good question because my 98 ck 1500 GMC only has 2 sensors. 1 upstream and one down stream. they are both new but the wirinf on the up stream has stopped working . code 134 and 155. no activity showing.

My 98 gmc yukon 5.7 l. Is throwing a manufacturer 1345 code and it comes back to camshaft pos sensor is tjat right? Cuz my truck still wont start
I know this post is over a year old. But I just had the same problem with my 98 K1500 5.7. Would run but like pure garbage,after many hours of research I bought myself a snap on scanner. Code P1345 is cam/crank correlation fault. Aka your distributor is advanced or retarded on timing by X amount of degrees. Mine was positive 22.
I’m sure you have fixed this problem by now but for anyone else coming across it, you MUST have a scanner that is capable of reading Cam retard degrees and perform the re learn process once timing is set back to 0. Meaning the engine has to be at operating temp and you must bring it over 1000 rpm for the sensor to relearn what the degree is. May have to repeat a few times but it really isn’t that bad of a job to do yourself , orrrrr you can pay a lot of money and have a shop do it.
Anyone ever have any questions feel free to email me at a.snapp1015@gmail.com
I may be able to help I may not, always willing to lend a hand tho.
