DTC P0115: Engine Coolant Temperature Sensor Circuit: Notes

CAUTION: If ECM replacement is instructed in following testing, always ensure ECM harness connectors and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction. If ECM is replaced, ECM must be programmed with proper ignition key code for engine immobilizer system. For programming procedures, see COMPUTER RELEARN PROCEDURES - IMPORT article in GENERAL INFORMATION, or appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.

NOTE: If DTC P0110 and P0120 are output together, check for open circuit in E2 (Brown wire) between terminal No. 28 at ECM harness connector E10 and engine coolant temperature sensor. Repair as necessary. See WIRING DIAGRAMS article.

NOTE: For component location, see appropriate illustration in THEORY & OPERATION article.
