I got my ORY installed with O2 sims a yr ago. The SES light came on about 6 months ago. The code was for the O2 sensor. The dealership replaced the sensor. Yesterday the SES light went off again and same code. Do these sims just keep burning out? Should I bother keep buying new ones? Thanks

 

Yes, simms randomly die. If the code bothers you, replace the sim. If the code doesnt bother you, dont replace the sim.

 

My sims finally starting setting off an SES code after 1 year. I was told the computer eventually figures out that the sim is giving a repeating signal that does no correspond to driving speed and load. The only sure fire solution is to have the code disabled through PCM programming
