The voltage on my tps checks backwards.7.46 volts at idle and 2.40 volts at wide open throttle. Any ideas greatly appreciated.

Are you using the Merc tool?

No.Just using a multimeter and probing the blue and orange wires.
IDLE voltage should be .135-.150 7.46 wot disconnect temp sender on port head 2 brn leads turn unit all the way clockwise then back slowly. just did mine 2 days ago
Temp sensor has been unhooked and it checks 7.46 at idle no matter where you set the tps. It only changes when you move towards wide open throttle then it drops to what it should be at idle.
I'd say you have the wrong wires probed, I've seen a manual that said to probe the wrong colours...try different combinations, I forget which but you'll work it out after a few attempts
Or buy the tool and stop poking holes in insulated, sealed wires.:rolleyes:Quote:
