This is the CEL for the 2nd heater circuit failure, which is because its reading bad emmisions. I have had this CEL now because of not having a caytalytic converter. I know that most people say the only way to get rid of this CEL is to get one, but I really don't want to have one on there and I need the straight pipe.

I tried putting like a 1 inch offset on the test pipe thats in there and it got rid of the code for a while, but it seems to be comming back again. Is there any ideas on what I can do to get rid of this code other than a catalytic converter? Any ideas would be great

 

heater circuit is a bad 02 sensor. p0420 would be a bad cat.

I believe the 02 sensor works? Are you sure I would get that code for bad emssisions on a 99 EM1? The circuit still works because my speedo still works and my alternator still charges etc. So theres a completion of the circuit through the 02 sensor... can it still be bad?

 

every time i got a 02 heater code i changed the 02 and fxed the problem

 

Do you have a cat?

Just get a Magnaflow Carsound high flow from eBay. Offer $45 and you'll get it.

 

I don't have an ebay account.
