DTC P0510: Closed Throttle Position (TP) Switch Failure: Notes

NOTE: Closed TP switch is built into TP sensor. For DTC P0510 test purposes, TP sensor will be referred to as closed TP switch. For terminal identification, see TP sensor under TERMINAL IDENTIFICATION . For circuit and wire color identification, see WIRING DIAGRAMS - 3.5L article.

NOTE: Do not replace the Engine Control Module (ECM) until a through terminal check reveals there are no short/open circuits. Check that the ECM ground circuit is normal before checking for the cause of the problem.
