[drago1217]

so i wanted to check the codes before i take the car back to the car lot. they are supposed to take care of the check engine light but i get the feeling they are just gonna try and rig it, ssooooooo, i will tell ya'll the codes and any helpful info on how to fix these would help out tremendeously.

p0141 (o2 heater sensor malfunction bay 1) or some shit like that.
p0161 (o2 heater " bay 2)
p0410 (secondary air injection system)
p0420 (catalyst system efficiancy below threshold)
p0430 (" " " " " ) or some shit like that.


any ideas on where these sensors are and what would cause these malfunctions.

Does the car have aftermarket headers? Rear 02's, secondary air and cat codes should be tuned out if they've been removed. If the car is stock you can look up the codes for your year at gearchatter.com for the descriptions/diagnostics.

Makes sense it does have headers and aftermarket exhaust also a wet kit system would that be the secondary air induction code

Thought that might be the case. Secondary air system was most likely removed when the headers were installed. See if the "car lot" will help pay for at least a diagnostic/have the codes turned off.
