DTC P0120: Throttle Position Sensor Circuit: Notes

CAUTION: If Engine Control Module (ECM) replacement is instructed in following test, always ensure ECM electrical connectors and ground circuits are okay. If either are defective, repair and repeat testing to confirm ECM malfunction.

NOTE: If DTCs P0110, P0115 and P0120 are output simultaneously, the E2 sensor ground circuit at terminal No. 18 (Green/White wire) at ECM electrical connector E6 may be open. See WIRING DIAGRAMS article. For ECM electrical connector terminal identification, see Figure. It may be necessary to check Green/White wire between splice I13 and terminal No. 18 at ECM electrical connector E6. Splice I13 is located behind passenger's side of instrument panel. See Figure.
