Whoa there, chill out. If you explained what a CPS sensor was (maybe not using a TLA?) and where he could find out if he had one or not that might have been more helpful. I agree, taking it to a garage would be the best bet, but he explained he wanted some advice incase it was a known problem and to arm him with some questions to ask his matey bey who knows whats going on. Advice is free, a garage isn't.
