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

WARNING: This page is about a different car, the 2000 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
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 P0105, P0106, P0110, P0115 and P0120 are output together, check circuit E2 (Brown wire) between terminal No. 9 at ECM harness connector E5 and junction connector J8. Repair as necessary. See WIRING DIAGRAMS article.
