I'm sure this topic has been discussed already. I can't get this code to clear. If someone could direct me to the thread that I'm sure is already out there that would be great.
Thanks

Fire up the old search engine. :rofl:
The code is telling you the H02S sensor is not switching enough voltage.
Does the code set engine cold or hot?
Any other codes?
Could be bad 02 sensor or wiring or 02 sensor heater circuit.
