SYMPTOM
P1115-GENERAL TEMP SENSOR PERFORMANCE

WHEN MONITORED
Engine off time is greater than 480 minutes. Ambient temperature is greater than -23° C (-10° F).

SET CONDITION
After a calibrated amount of cool down time, the PCM compares the ECT Sensor, IAT Sensor and the Ambient Air Temperature Sensor values. If the (AAT and IAT), (AAT and ECT) and (ECT and IAT) are all less than a calibrated value, then the DTC will set.

POSSIBLE CAUSES
- Good trip equal to zero
- Other possible causes
- Signal circuit shorted to battery voltage
- Temperature sensor voltage below 1.0 volt
- Signal circuit open
- Sensor ground circuit open
- Signal circuit shorted to ground
- Signal circuit shorted to sensor ground
- PCM low
- PCM high
