Motor temperature sensor
The signal from this sensor is used by the processing unit for controlling supply and ignition systems, and to activate the fan.
The sensor is screwed into the intake manifold.
The sensor is a thermistor.
On the sensor supplied with a constant voltage and removes the signal is determined by the change in the current sensor temperature change.
In the event of sensor failure (warning lamp on the instrument panel) control is transferred to the reserve scheme, which uses the default input parameters.
Check
| PERFORMANCE ORDER | | 1. To check the sensor is necessary to remove it and measure the resistance at different temperatures. | | 2. Never test the sensor on the vehicle. | | 3. Full scan sensor circuit and the engine management system is carried out in car-care center service. |
|
Withdrawal
| PERFORMANCE ORDER | | 1. Disconnect the battery from weight. | | 2. Drain the engine has cooled down to the level of the liquid thermoswitch. | | 3. Disconnect thermoswitch. | | 4. Carefully remove the thermoswitch, remove the seal (if provided). |
|
Setting
| PERFORMANCE ORDER | | 1. Clean thermoswitch and apply thread sealant. | | 2. Replace the seal (if provided). | | 3. Next, the assembly is done in reverse order. |
