[QUOTE="Lil ugly, post: 759547, member: 3188"] Have you double checked the fuses and connectors? Put a voltmeter to the TPS sensor via the backside of it. I believe the grey wire is power from the ECM and the black wire is ground from ECM. The remaining wire should send the signal back to the ECM. Power should be 5 volts DC or something like that . Another check is have someone watch the throttle body when the key is turned on. The TPS should cycle a small amount to make sure the throttle plate is set correctly. It may just be stuck and not moving since the vehicle was sitting. This would throw of the return signal and cause the ECM to believe it is a failed sensor putting it into safety mode. [/QUOTE]
