A/C Sunload Sensor Diagnosis

Condition(s):

- On-Board Diagnostics DTC 05

Possible Source(s):

- A/C sunload sensor shorted.

Action(s) to Take:

- Disconnect battery cables. Disconnect wire harness connector at A/C sunload sensor and disconnect both connectors from EATC control assembly.

NOTE: Check A/C sunload sensor for a short using an ohmmeter. The A/C sunload sensor is a photodiode so there should be some unspecified resistance across the terminals depending on the light available in the area. The only test that should be made is for a short circuit (zero resistance). If resistance is zero ohms, replace the A/C sunload sensor.

- Check for continuity and for possible shorting between two wires (Pin 3 and Pin 16). Repeat if necessary. Reconnect battery cables.
