9000 CS L4-2290cc 2.3L DOHC Turbo EFI (1996)
The car is fitted with an electronic speedometer. Transmission between the gearbox and the speedometer is electronic.
When ignition switch 20 is in the Drive position, current is supplied to pin 1 of the sensor, vehicle speed sensor 132, which sends a pulsed signal
to the Cruise Control and speed warning systems, as well as to other systems.
The pulse frequency is 2,458 pulses per kilometer.
Vehicle speed sensor 112 is mounted in the gearbox. It sends an alternating current signal, the frequency of which varies with the speed of the car,
to electronic speedometer 111 in the main instrument display panel. The pulse frequency of vehicle speed sensor 112 is four times that of sensor
132.
FAULT DIAGNOSIS HINTS
1. Check that current is supplied to pin 1 of the speed sensor.
2. Check that there is no open circuit in sensor 112.
3. Check the connectors, wiring harness and ground connections.
