Repair and operation of the car

Check of usefulness of a state and substitution of the switch of sensor of pressure in system of hydrofortification of a wheel (PSP)

The switch of sensor PSP is in use in models produced for the market of the USA and one closes normally key. The sensor switch is lit in the hydraulic line and is located near to a case of the transfer of torture. In strong turns of a steering-wheel (for example during the parking or in abrupt turns) the pressure considerably increases in the system of the hydrofortification also of the switch of sensor PSP, desconectar-se, informs in this ECM/PCM that like appropriate elevators that waste time you return, compensating for the growing load of the motor. In the moment of violations of the functioning of the switch of sensor the system of the autodiagnostic one of OBD brings the corresponding code of the bad functioning in the processor memory.

To check

ORDER OF REALIZATION

1. If the motor goes deaf in the commission of maneuvers during the parking of the car, check the usefulness of the functioning of the switch of sensor PSP. The bad functioning of the switch of sensor can lead also to constantly lifted motor turns.
2. Desconecte an electrical system of the switch of sensor.

3. Join an ohmmeter when to they were taken of sensor (companion seen an illustration).

5. The motor begins in the only turns.
6. Bring halls of wheels of the car in the right-lined situation and consider the indication of an ohmmeter that in this case will be near to the zero.
7. Rotation of a steering-wheel in any direction, it looks at indications of the instrument of measuring. In the moment from the approximation of a steering-wheel to some of extreme provisions the switch of sensor PSP has of desconectar-se what is confirmed for the infinite indication of an ohmmeter.
8. In negative results of the check they substitute the switch of sensor. If the sensor switch is useful, it is necessary to check placing of the only turns of the motor.

Substitution

ORDER OF REALIZATION

1. Desconecte both wires of the battery.

The negative wire always has of desconectar-se first of all and to be joined in the last one. If the stereosystem established in the car if it equips of a security code before desconectar the battery they secure what has the correct combination of the introduction of the equipment to the action!

2. In case of the necessity also they it establish a front of the car to a poddomkratta in stakes.
3. Desconecte ties an electrical system of the sensor and results the last of the connection of nipple.
4. Establish replaceable to the place of the left sensor they exchange and lower the car in the land.
5. Withdraw of a hydraulic way of the system of the traffic jams of air traffic of amplifier of direction (to see the Chief Podvesk and driving). In case of the correct liquid level of necessity (to see the Front Regular maintenance).
