I'm new to this forum and so far its great. I have a 2001 dodge dakota 2 wheel drive and the service 4 wheel drive light came on. any suggestions on how to get rid of it? a
Also the check engine light came on, the problem code is p0161 which I read was the oxygen heater sensor. Any suggestions on this, would that mean the 02 sensor is bad?
Thanks

 

yeah you'll need the o2 sensor replaced make sure you replace the correct one when you do though. I dont know about the 4 wheel light thats strange sence your truck is 2 wheel drive.

 

My service 4wd light came on a month or so ago. I thought it was oddest thing considering like you I have a 2wd. I waited a day to see if it would shut itself off and ended up resetting the PCM.
