So I start my car and I notice the exahust note is lower and louder than usual, I rev the engine and my bov is even louder than normal, theres a more noticable vibration from the engine and slight knocking sounds. I drive to pick a friend up and then when I restart the car it happens

CHECK ENGLINE LIGHT COMES ON!

Plug it in to the scanner and code PO 135 pops up O2 sensor heater malfunction!

WTF is this I know what a 02 sensor is but what is the malfunction what could have caused it and how can I fix it?

HELP DSMers

 

You probably need to replace your O2 sensor then. Do you have a blinky gauge air fuel gauge?

 

No I dont have a air/fuel gauge I've been meaning to get one Whay do you ask?

 

if you 02 sensor was bad, it would probably just sit in one spot at all times

 

I had the same problem!!! I haven't done anything about it...let me know how everything works out so I can fix mine!!!

 

do you have stock exhaust ? i know when you take out the cat it throws that code.

 

I dont have stock exhaust. My TPS was bad so I replaced that and the CEL went off. Then I got in the car the next morning and the CEL came back on. I took it to Autozone and they hooked up the computer and it gave me PO135
