Conditions

B2355

Evaporator temperature sensor. Shorting to ground
Evaporator temperature sensor. Open circuit/short to B+
Evaporator temperature sensor. Out of range





Fault symptoms
Temperature sensor in evaporator stops functioning, which means that the A/C system does not supply cold air.

Diagnostic help
The evaporator temperature can be read on the diagnostic tool.

A reference resistor is useful when diagnosing a faulty sensor. This would give the following readings on the diagnostic tool:
- 6.2 kohm gives approx. 20 °C
- and 11 kohm gives approx. 8 °C.

See Evaporator Temperature Sensor, "Application and ID" for the association between temperature and resistance.
