I keep getting an ses light when decelerating that goes away after a couple minutes and once the car is warmed up it stays off. I checked it with a scan tool and it gave me a code 22 (open in tps circuit). I couldn't see anything wrong with a visual inspection, but was afriad to really dive in. Any ideas on where to start?

 

take a voltage reading between the blue and black wire. at idle it should be .54vds ish. if your dont get any reading could be bad tps or ecu.
