Question about 2007 Cadillac SRX
The engine light came on> OnStar says its an O2 sensor. Took it in and svc mgr says there is some preventative maintenance that he could perform: Fuel System Service and Engine Induction Service. Do you think this a worth while service?
Recently had the same problem my friend......The O2 Sensor can simply mean that your gas cap is not on tight enough, or possibly your purge solenoid.
I am just a regular average guy, and I am retarded when it comes to cars, so I asked a mechanic on ask.com cadillac, or something like that...anyways......The purge Solenoid only costs about 35 dollars, and is super easy to replace. The hard part is getting your card started again after your battery is hooked back up because of the Cadillac theft detterant system. After you put the Purge Solenoid in, and hook up your battery make sure you do the following to bypass the security system:
1. Turn key in ignition all most all the way on, but don't turnover.
2. Leave in this position for 10 min exactly
3. Turn key back for five seconds
4. Repeat this sequence four addtional times.
5. On the fourth time the car will turnover, and you are good to go.
I hope this helps, cause cadillac almost bent me over on this one....
