Yes i did. The CEL came on again. I was driving under noraml conditions too. IDK must be broke! lol

 

Did you get this checked out? What was the problem?

 

Just take it to the dealer. The car is still under warranty.

 

Even though i installed the unit myself?

 

Well unless you damaged the A/F ratio sensor (don't know how you could have) or installed something wrong you full warranty is still intact. The only thing that isn't covered under the "Factory Warranty" is the S/C. It's covered by the TRD warranty parts only warranty if it was installed properly.

 

you said you never touched either afr and o2 sensor but it never hurts to check it against a ohmmeter.

on the service manual it shows how much resistance on each connector. make sure battery is disconnected.

 

Awesome.. ill look into and let you guys know what i find out...

 

My SC'd Matrix threw a CEL regarding "low catalyst efficiency". The cat was burned out because I put an intake on the TRD SC, and that caused the a/f to lean out and exhaust to get hot enough to ruin the cat.

Cats don't burn out for no reason - if you get it "fixed" under warranty - you'll end up with the same CEL in 3 weeks, unless they find the reason why your cat burned out.

 

i have megan combo and im using antifoulers from kragen, its been 90+ miles and no CEL

good luck and see if your AFR sensor is good. i got mine for 170+tax.
