Optima V6-27L Intake Air Temperature Sensor Component Diagrams
Troubleshooting Procedures
TROUBLESHOOTING HINTS
The MIL is ON or the DTC is displayed on the HI-SCAN under the following condition;
1. When the intake air temperature is detected as below -40°C or higher than 120°C.
2. Input from intake air temperature sensor is below 0.1 V or above 4.8 V when engine is in a full warm-up condition.
Using Voltmeter
SENSOR INSPECTION
1. Use the multimeter, measure the sensor resistance.
2. Measure the resistance between the IAT sensor terminal 1 and 2.
3. If the resistance deviates from the standard value, replace the intake air temperature sensor assembly.
