9. The electromagnetic N1, N2 valve of the switching lever 10. Switch of system of blocking of ignition 11. The electromagnetic valve of the switching lever 12. Coupling speed sensor 13. Sensor of speed of rotation of a bent shaft 14. Temperature sensor of cooling liquid

Arrangement of the socket of the elektromaknitny valve (4-cylinder engines)

In 4-cylinder engines the socket of the electromagnetic valve is located in peredny speak rapidly transmissions, directly over the switch of system of blocking of ignition.

Arrangement of the socket of the elektromaknitny valve (6-cylinder engines)

In 6-cylinder engines the socket of the electromagnetic valve is located opposite to the switch of system of blocking of ignition.

Check of electromagnetic valves

1. Electromagnetic N1 and N2 valves 2. Compressed air 3. Accumulator

PERFORMANCE ORDER

1. To check electromagnetic valves, give accumulator tension on contacts of each of valves. 2. If valves are serviceable, you have to hear click. 3. Send a stream of compressed air to each of valves, pressure about 65 psi. Valves should not pass air. 4. Again give accumulator tension on contacts and be convinced that the valve opened.

CODES OF MALFUNCTIONS

The electronic control system is equipped with function of automatic search of malfunctions. The code of malfunction is brought in memory of system, and then highlighted on the display panel of a condition of the engine.

Malfunction code	Cause of defect
PO500	The speedometer sensor (N1 speed sensor) is faulty, conducting or short circuit is damaged
PO750	The electromagnetic valve of the switching lever A (the electromagnetic valve of the switching N1 lever) is faulty, jammed the valve in an open or closed position
PO753	The electromagnetic valve of the switching lever A (the electromagnetic valve of the switching N1 lever) is faulty, conducting or short circuit is damaged
PO755	The electromagnetic valve of the switching lever B (the electromagnetic valve of the switching N2 lever) is faulty, jammed the valve in an open or closed position
PO758	The electromagnetic valve of the switching lever B (the electromagnetic valve of the switching N2 lever) is faulty, conducting or short circuit is damaged
PO770	The electromagnetic valve of the switching lever E is faulty, jammed the valve in an open or closed position
PO773	The electromagnetic valve of the switching lever E is faulty, conducting or short circuit is damaged
P1520	The switch of lamps of a stoplight is faulty, conducting or short circuit in a switch chain is damaged
P1705	The coupling speed sensor is faulty, conducting or short circuit in a sensor chain is damaged
P1765	The electromagnetic valve of the lever of switching is faulty, conducting or short circuit in a valve chain is damaged
P1780	The switch of system of blocking of ignition is faulty, conducting or short circuit in a switch chain is damaged
