DTC P0113 - Intake Air Temperature (IAT) Sensor
- Turn ignition on. Check IAT sensor using scan tool. If less than -4°F (-20°C) or less is not indicated, problem is intermittent. Check for poor connections or loose wires in IAT circuit between IAT sensor connector and PCM connector. See WIRING DIAGRAMS section.
- If -4°F (-20°C) or less is indicated, disconnect IAT connector. Install jumper wire between IAT sensor connector terminals. Using scan tool, check intake air temperature. If -4°F (-20°C) or less is not indicated, replace IAT sensor.
- If -4°F (-20°C) or less is indicated, turn ignition off. Connect jumper wire between PCM connector terminals D8 and D11. See Figure . Turn ignition on. Using scan tool, check intake air temperature. If -4°F (-20°C) or less is not indicated, repair open in wiring between IAT sensor and PCM connector terminals D8 and D11. See WIRING DIAGRAMS section. If -4°F (-20°C) or less is indicated, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.
