| 1. The supply air temperature sensor is a thermistor, ie, its resistance decreases with increasing temperature sensor. |
| Models with 4-cylinder engine and a pattern with a 6-cylinder engine 1998 release |
| 2. Check that the sensor resistance at room temperature is about 35,5-39,2 kW. Heat the sensor to a temperature of 60 ?� C and check that the resistance is reduced to 7-8 ohms. Replace the sensor if it is faulty. |
| Models with 6-cylinder engine 1993 - 1997 Release |
| 3. Check that the sensor resistance at room temperature is about 2-3 ohms. Heat the sensor to a temperature of 60 ?� C and check that the resistance is reduced to 400-700 ohms. Replace the sensor if it is faulty. |
