Wire diagram for CPS sensor
 

Hi. I have a 2009 Volvo S40 T5 with automatic transmission and 94K miles. I had a CPS fault code P0340. I've replaced both sensors and reset the fault code but it continues to return. The car starts but runs as if it's in limp mode. I've also checked the condition of the timing belt to see if it's possibly jumped a tooth. The belt is tight and I can clearly read the writing on the belt, leading me to believe the prior owner had it replaced in the not so distant past. I'm looking for the wire diagram so I can wring out the circuit but haven't been able to locate one. Could someone please point me in the right direction?

thank you
Steve

It's not your "sensors" - (never replaced a bad one) You need to look somewhere else (correct cam timing?)

Hoonk. You were correct. It wasn't the sensors or the wiring. I checked the timing and the intake camshaft was off by 2 teeth. It's odd because the belt looks fairly new, but I'm going to replace it along with the idler pully, belt tensioner and water pump. Thank you for your insight
