DTC Troubleshooting: 14
|DTC 14:||A Short in the Evaporator Temperature Sensor Circuit|
|1.||Disconnect the evaporator temperature sensor 2P connector.|
|2.||Test the evaporator temperature sensor.|
Is the resistance within the specifications shown on the graph?
YES - Go to 3.
NO - Replace the evaporator temperature sensor.n
|3.||Disconnect the negative cable from the battery.|
|4.||Disconnect ECM/PCM connector E (31P).|
|5.||Disconnect climate control unit connector B (16P).|
|6.||Check for continuity between the No. 12 terminal of ECM/PCM connector E (31P) and body ground.|
Is there continuity?
YES - Repair short to body ground in the wire between the ECM/PCM, the climate control unit and the evaporator temperature sensor.n
NO - Go to 7.
|7.||Reconnect ECM/PCM connector E (31P).|
|8.||Turn the ignition switch ON (II).|
|9.||Measure the voltage between the No.12 terminal of ECM/PCM connector E (31P) and body ground with the ECM/PCM connectors connected.|
Is there about 5 V ?
YES - Substitute a known-good climate control unit, and recheck. If the symptom/indication goes away, replace the original climate control unit.n
NO - Substitute a known-good ECM/ PCM, and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n
