Warning! Before performing the operation, be sure to read the section «Safety measures for the maintenance and repair of the engine management system».
To do the job, you will need a multimeter and a thermometer.
Examination
Checking the temperature sensor of the air entering the cylinders consists in measuring its resistance at various temperatures and comparing them with reference values (are shown in the table). Remove the sensor to check (see below), connect a multimeter to it in ohmmeter mode and take the readings of the device. We measure the temperature of the air with a thermometer. We compare the obtained values \u200b\u200bwith those given in the table. If they do not match, replace the sensor.
Table 9.2.4. Intake air temperature sensor resistance
Replacement
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
2. Disconnect the wiring harness block from the sensor.
3. Carefully remove the sensor from the air inlet pipe using a slotted screwdriver.
4. Install the sensor in reverse order.
