I just installed my RP supercat. I put a new O2 sensor in at the same time. After 60km of driving the CEL is now on all the time. It flashes when I am at full throttle, then will return to solidly on afterwards.

Is this a problem, or is the CEL supposed to be on??? Even with a header and highflow cat my old car never had a CEL.

Should I cought up and have Mazda read the code that goes with it?

yes I searched too, but couldn't find anything specific.

Thanks,
Juergen

Flashing CEL means something else.

Turn it back to stock and see what happens. Thats what I would do.

Do a search.. I think you need a specific O2 sensor, otherwise other brands do not work.

you need the code to know what is is for sure. But right now I would be guessing thatnew O2 sensor

TAke it to autozone/pep boys/partsplus/whatever. Most name brand parts places will read the code for free.

aamco will read the code for free as well.

I have the RP supercat and have had no CELs. Actually, I've never had a CEL with the car. Other option is to post a thread in your regional forum, to see if anyone local to you has a the scanalyzer tool...

I get codes read at Autozone all the time.

reset your computer by disconnecting the negative battery cable and letting it sit overnight if your havent done so already

spd frk, just wondering if you got any resolution on this. I installed the RP SuperCat and after less than 300 miles I have a CEL on all the time. Before that no CEL's. I don't want to clear the code until I know what caused it. (By the way, I used the stock 02 sensor).

Did you replace the gasket or use the old one?
