DTC P0110: Intake Air Temperature (IAT) 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 (Green/White wire) between ECM harness connector E5 and splice I13. Repair as necessary. See WIRING DIAGRAMS article.
