2002 Pontiac Montana Repair Question
P0135 Error Code and Incomplete O2 and Catalyst Monitors
Asked by dudenamedricAnswer
Where is the o2 sensor located you replaced?Also the catalyst is the cataltic convertor.It not ready because of the code your setting most likely.
It was bank 1 sensor 1, screwed into the top side of the exhaust pipe on top of the exhaust manifold. How do I set the right code?
So its a 4cyl engine?Also what do you mean set the right code?The reason the monitors arent setting is because of the code your setting.Also when ever you disconnect the battery or clear codes that clears/resets the monitors so they have to be relearned again.
No, it's a 6 cyl. I wasn't sure if you meant a code I myself was setting or the vehicle. We also didnt disconnect the battery, and I don't think we cleared codes. So are you saying that the light coming back on isn't anything to worry about? Will it pass an Indiana emissions test?
the light cannot be on and must be repaired correctly to pass emissions.
take it to a shop for a real diag and they will tell you the failures and the needed repairs.

If the ligh is on what coees do you have now since the repair?Also with the light on its a auto fail for emissions.Plus the monitors wont set.
I'm going to take it to AutoZone today to get another diagnostic. I'll fill you in on the code once I get back.
autozone are parts salesman, not techs. they will sell you the world.
you need a real shop to check it for you, not a parts house.
Roy
Well it's Sunday and it's free, so I'm gonna see what it says and then make some calls tomorrow to see if any shops in the area do free checks as well
Let me know what you find.
