NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
L1 CHECK THE EVAPORATOR TEMPERATURE SENSOR RESISTANCE
Ignition OFF. Disconnect Evaporator temperature sensor C296. Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C296-1 (component side) | C296-2 (component side) |
Compare the evaporator temperature sensor measured resistance with the table below.
Ambient Temperature °F (°C) | Resistance ohms |
-39.9°F (-40°C) | 98,625 - 103,275 ohms |
-4.0°F (-20°C) | 28,640 - 29,600 ohms |
32.0°F (°C) | 9695 - 9895 ohms |
68.0°F (20°C) | 3675 - 3810 ohms |
77.0°F (25°C) | 2950 - 3050 ohms |
86.0°F (30°C) | 2370 - 2565 ohms |
103.9°F (40°C) | 1565 - 1635 ohms |
Is the resistance within the specified values for the temperatures?
Yes | GO to L2 | |
|---|---|---|
No | INSTALL a new evaporator temperature sensor. REFER to: Evaporator Temperature Sensor (412-00 Climate Control System - General Information, Removal and Installation). | |
L2 CHECK THE EVAPORATOR TEMPERATURE SENSOR INPUT CIRCUIT FOR A SHORT TO VOLTAGE
Ignition ON. Disconnect FCIM C2402A. Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C2402A-19 | Ground |
Is any voltage present?
Yes | REPAIR the circuit. |
