Hey everybody. I have had my cel on since I was running no cats. I got the apr program that disables the rear o2 sensor from throwing a code, but about a month ago i got a cel and had it pulled. It was the front o2 sensor. Ok, I just got a new exhaust system, with the cat back on, and still have the same code plus two more. Here are the three codes. Can anybody tell me, which i am hoping so, if they are related? For example, if one code is setting the other ones off?

P0036 H02S Bank 1 Sen 2
Heater Circuit


P0136
o2 sensor
Circuit Malfunction


P0352
Ignition Coil B
Primary / Secondary
Circuit Malfunction



Any help would be great. I have a new o2 sensor on the way.

Thanks in advance.

 

The first two are, replace the rear 02 like you are planning and that should clear them up, the last one is a bad coil duh, may want to look into getting that replaced. I know ecstuning.com has replacement ones that are supposed to be pretty good. Good luck.
