Hey guy's

I have replaced my o2 sensor in all banks and I still get a p0141 code. I am not sure where to go from here. I sprayed all contections with contact cleaner to ensure they are making contact, probed for voltage and still that nasty p0141. I checked out my Haynes book and no options? For a diagnostic what should I do now?

Thanks a lot

Jason

Have you reset the engine light after these attempts? If not, you may need to do so and see if the light comes back on again.

Hey guys;

Thanks for the response. I have reset the computer, installed a new sensor and have check the 20amp fuse that is adjanctant to sensor. Still no luck and again that pesty p0141. I have spoke to a friend and he thinks it could be an injector but wouldn't that fault another code?

Thanks a bunch

Jason

Hey thanks for the response.

Well, I clear the code each time and within 50 to 60 miles that darn check engine light comes up again. I replace all O2 sensors and still I get a p0141.

Thanks

I don't believe this is an issue with the injectors..

P0141 is heated oxygen sensor circuit malfunction

You stated you arleady checked the supply voltages to the sensor?

If not, do the following.
