wassup guys, my service engine light came on today, and i pulled a 0510 code. i checked the haynes manual and told me it was a "downstream oxygen sensor maximum voltage monitor fault." I'm not really sure what that means, and i was wondering if anybody can clarify that? thanx

 

Read the stickies and the many FAQ's about O2 sensors.

Good luck

You have to replace the sensor. If your car is Cal spec then prepare for another one soon. I had mine gone in the same time.

 

anybody know where is the cheapest place to get a sensor?

If you call, speak with Mike; he's very helpful.
