Check Engine Light Is On After Wife Accidently Filled Up With Regular Gas
Hey All!
I've got a problem here. My wife accidently filled-up with regular gas on our '97 XJ6, and about a day later the check engine light went on. I got the diagnostic message read, and they said it was the oxygen sensor - they weren't sure if it was related to the regular gas. I've been trying to turn off the check engine light to see if it'll come back on again now that the jag has had several tankfuls of yummy premium gas. I've tried disconnecting the battery for an hour, and also disconnecting a fuse called "instrument pack" for an hour (which I read from a post regarding a non-X300 XJ6). I'd love to hear if someone's got the magic formula out there - thanks!

RE: Check Engine Light Is On After Wife Accidently Filled Up With Regular Gas
The codes for O2 sensors are normally pretty accurate. If they code indicated a fault with O2 sensor, is probably O2 sensor. I think on your vehicle (I am not too up on the pre 97 cars) you can swap the connector with other O2 sensor. Connector I think is in right front fender area. If code changes to other O2 sensor, you know you have a faulty sensor.
Chances of cheap gas causing light is remote. Likely coincidental is all. Anyway, look at the O2 sensor connectors and see if you can swap them from one to the other. Best way to check sensor or another fault.

hi ralph, i know this was last year or so. for the future, just in case it happens again. first, the problem is/was your fuel. if the manufactor specs. says (PREMIUM FUEL ONLY) or unleaded fuel only, etc. THATS WHAT YOU USE! point blank. the o2 sensor picked this up daring the drive cycle, which is good. its doing its job! replace the correct fuel and clean the o2 sensor(s), then have the codes removed and the check engine will turn itself off daring your new drive cycles. ps: reminder; whenever you do something different to a thing and the outcome changes, the problem is in the change. reverse your actions and the problem usually go away. pending theres no damage!
