Hello all -

New to the forum. Glad to have a resource like this. I am working through aproblem on my 2005 Chrysler T&C.

P0135 Generic 02 Heater Circuit (Bank 1, Sensor 1) error code.

I've replaced the front O2 sensor and the "check engine" light pops back on.

With a little research (Inet) - I came across a "TSB" (Technical Service Bulletin???) # 800805 & 5005 or

Any way to obtain this? I hate to go to my dealer (they're the most unfriendly bunch of people I've ever met). Since I didn't buy it there, I am a second class citizen. They'd be happy to charge me $300 to tell me I have a "P0135 error code" (which I already know).

Car seems to run OK. Just want to fix the light (check engine).

Thanks for your help-

that TSB requires the PCM software to be updated if U are under 8 years or 80k miles its under federal emissions warranty if not expect to pay about an hours labor.

 

Yup.. had it done to my 05 under warranty. There have been a few out here chasing O2 sensor problems and I have keep saying a PCM flash is required. I think Chrysler change the resistance of the 02 sensor (heater circuit) now and the the only way around it is to get the software updated. Don't quote me on this as it has been a while since I read the TSB and can't seem to find the details of it anymore.
