I checked this CEL code for my bro in law.. and I'm just curious as to what sensor would give this code... I initially thought it would be the secondary o2, but that CEL code is 65.... any ideas as to what sensor would send this signal??


TIA

 

No one??? BUMP

 

COME ON!!!! ANYONE????

 

No Tech guys on right now?

 

so you mean to tell me that NO ONE on honda tech has had this happen?

 

i would lik to know ths as well as i hae the same code. I think its my cat and will probably have to get a new one but im going to get a test pipe and an exhaust for it later since the cat is way too expensive, pe ace.

 

The secondary O2 sensor is whats responsible for letting the ECU know that the catalytic converter is functioning correctly. Since the converter uses O2 to do its job, the signal coming from the 2nd O2 usually shows a rich condition. When the 2nd O2 begins tracking the the primary O2 signal, the ECU is left to believe the converter isn't working correctly.

Did he install a test pipe or high flow cat?

 

No, but I think he has bad rings.. and that probably contaminated his cat. Thanks.. I assumed it was the secondary o2.. but wanted to be sure..

thanks dude.
