Symptom: P0113-INTAKE AIR TEMP SENSOR VOLTAGE HIGH When Monitored and Set Condition: P0113-INTAKE AIR TEMP SENSOR VOLTAGE HIGH When Monitored: With the ignition on and battery voltage greater than 10.4 volts. Set Condition: The intake air temperature (IAT) sensor circuit voltage at the PCM goes above 4.9 volts. POSSIBLE CAUSES INTERMITTENT CONDITION IAT SENSOR INTERNAL FAILURE IAT SENSOR SIGNAL CIRCUIT OPEN SENSOR GROUND CIRCUIT OPEN IAT SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE PCM TEST ACTION APPLICABILITY 1 Turn the ignition on. t, read DTCs. Is the Good Trip Counter for P0113 displayed and equal to zero? All Yes → No → 2 Turn the ignition on. t, read the IAT voltage. Is the voltage above 4.6 volts? All Yes → No → 3 Turn the ignition off. All Yes → Repair the IAT Sensor Signal circuit for a short to voltage. No → 64 DRIVEABILITY - GAS |
