OK this might be a dumb *** question.

I have the CEL light on, pulled codes p0430 and p0420. I wanted to buy a o2 sim. to solve the problem . Now the question is do i need 2 o2 sim??? 1 for each o2 sensor?? or do i get the dual o2 sim and that will solve both o2 problems??? Please help asap...


thanks,

P.s. Anybody in the philly area willing to install this for me??? will compensate

 

Get one dual o2 sim for both sensors and they are really easy to install.

 

The dual output sim will suffice because it simulates both O2 signals.

The install is easy really. Take a look at the install instructions in the How-To Sticky.
