Check of a condition and replacement of the sensor of speed of movement of the car (VSS)

VSS is established on a case of transmission and represents the sensor with variable magnetic resistance. The sensor develops a sinusoidal signal of the alternating current which frequency is proportional to speed of movement of the car. Information arriving from VSS RSM are used at management of duration of time of opening of injectors of injection of fuel and transmission switching. Besides, VSS is used as a speedometer drive. Failure of the sensor leads to record in memory of OBD of the corresponding codes of malfunction.

CHECK

 PERFORMANCE ORDER

 Serviceability of functioning of VSS can be checked on adequacy of indications of a speedometer.

1. Remove VSS from a transmission case.

2. Connect the voltmeter to two plugs of the sensor and switch a measuring instrument in a mode measurement of an alternating voltage. Start to rotate manually a driving gear wheel of the sensor, - the voltmeter should register a signal amplitude about 0.5 Century.

3. In the absence of alarm tension the sensor is subject to replacement.
4. At positive results described above check check on break electroconducting on a chain site between the VSS socket and an instrument guard (see schemes of electric connections at the end of Head Onboard electric equipment). If electroconducting as it should be, drive away the car on car repair shop for carrying out diagnostics of RSM and performance of the corresponding regenerative repair.

REPLACEMENT

 PERFORMANCE ORDER

1. To Poddomkratta the car also establish it on props.
2. Disconnect from the sensor of speed electroconducting.

3. Having turned out a coupling bolt, weaken a collar and take VSS from transmission.

4. Check a condition of a landing sealing ring of the sensor, in case of need make replacement.

5. Installation is made upside-down.
