2001 S40...130K...My CEL went on...had it checked for codes...700/705...PNP switch. He turned off the CEL, I drove it about 50 miles and it returned. I ordered the new part. Had the CEL turned off...it's been about 100+ miles, the CEL has not returned !!! Do I change the PNP, or assume that the unit is working fine? If I get another 50+ miles and still no CEL...does that confirm my decision? The part was $100...the labor, I can do...except it seems to get a tad hairy with the adjustment phase of the install...Otherwise I would not hesitate to install it... Ahhhh....what to do, what to do.
