Just to be on the safe side I ordered a new OEM relay on Ebay. It was only $200.00. I drive from L.A. To Vegas a lot on business. Sometimes coming back after midnight. It's worth $200.00 just to have piece of mind. I think the sensor and the relay ought to get that damned "check engine" light off. A few rat traps wouldn't hurt either. I live in the foothills and those little F*****s are hell on cars. I had 10 guage cable that went straight to the battery on my Jag. Filthy rodent got a big surprise when he bit into that. It didn't take CSI to figure out what happened.
