DTC P0120: Throttle Position (TP) Sensor Circuit: Notes

CAUTION: If ECM replacement is instructed in following testing, always ensure ECM connectors and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction.

NOTE: If DTCs P0110, P0115 and P0120 are output together, check circuit E2 (Brown/Black wire) between ECM harness connector E7 and splice I9. Repair as necessary. See 2.4L and 2.7L in SYSTEM WIRING DIAGRAMS article.
