96 ETC code P 0139 code p0139 others causes besides o2 sensor? can maf sensor be dirty?
Re: 96 eldorado touring code p0139 Re: 96 ETC code P 0139 Yep ^^^
We don't have the several thousand codes memorized yet ............. Do some homework. http://www.obd-codes.com/trouble_codes/gm/obd_codes.htm Re: 96 ETC code P 0139 DTC P0139 HO2S Slow Response Bank 1 Sensor 2
But his is a 96, wouldn't this be an OBDI vehicle? Or a bit of both OBD I & II? Or is that 95's?
I need a beer Re: 96 ETC code P 0139 '96 cars are mostly OBDII (enough so they comply with the Federal law). We can call '96 a transition year (sometimes when dealing with '96 vehicles you may need to go and check OBDI codes).
This code is OBDII and I found it for the OP:
DTC P0139 HO2S Slow Response Bank 1 Sensor 2
Basically replace that O2 sensor. Re: 96 ETC code P 0139 The '96 PCM codes are OBDII. I think most of the others where still OBDI until '97. Re: 96 ETC code P 0139 how long does code take to return after you clear it? i am getting 0140 which is no activity. i did change sensor 18 months ago. code went away but recently came back.
