B2355

Read the instructions below then start the fault diagnostic procedure.

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

B2355


Evaporator Temperature Sensor. Short 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.


For relationship between temperature and resistance, see .
