need help finding out what i gotta do to fix my probs with these codes...

first is P0135 and it says
upstream heated oxygen sensor circuit fault bank no. 1

second is P1000
OBD2 monitor testing incomplete

third is P1443
evaporative emission control system / vacuum system / purge control solenoid or purge control valve fault....

does anyone know what i can do to fix these codes??? i dont know much about the car, ive always been a chevy guy. i have a 97 GT auto... mods listed below... i wanna get them fixed ASAP... thanks in advance for any help..

P0135 check the actual plug of the O2 sensor on the passenger side in front of the cat. I had P0161 the other day and it was a similar thing with Bank 2 sensor 2. (you're bank 1 sensor 1). Either the plug on the sensor is loose or the wire that heats the O2 sensor is broken.

P1000 is related to that probably since the OBDII system can't do all of its sensor checks


P1443..no clue.

i got that last code w/ my dakota. it had something to do w/ the gas cap. no clue if it is related here.

-the code meaning " evaporative emission control system", just so theres no confusion

thanks alot, if anyone knows what the other code means id really appreciate the help...

since you have an off road midpipe...it will throw that P0135 code...sometimes even with MIL eliminators
the P1000 will come up all the time...it doens't mean anything really and doesn't cause the check engine light to come on...not for sure about the third one though.

change the gas cap first for the evap code if that doesnt work u will probably need to take it to a shop they will smoke test it and see the leak we got a otc smoke maching the other day and it is ok but i wouldnt recommend it not enough smoke

No no no. With an offroad pipe it will throw P0420 and P0430 for the catalyst system not working as well as it should. P0135 - Your sensor might be taking a crap. Clear the code and see if it comes back. If it does just go out and buy a new O2 sensor. I just had to buy a new one becuase one of mine took a crap (kept throwing P0153 - Slow circuit response bank 2 sensor 1). As for the other one, clear it and see if it comes back. If it does, you might need to replace a selenoid. P1000 is coming up becuase of those codes, as their not letting the systems of the car run through all their tests. Once you get them fixed, drive the car around with a mix of highway/city driving and itll go away.
