Terminal Arrangement Of ECM(PCM) Coupler(Viewed From Harness Side):

CIRCUIT DESCRIPTION
The speed sensor consists of the hall element (2), magnet (3), gear (1), etc. It is installed on transfer or transmission.

As the sensor gear is turned by drive gear on transfer (or transmission) output shaft, the signal voltage changes from high to low (or low to high). Such High / Low frequency increases in proportion with the vehicle speed and is sent to ECM (PCM) as pulse signals. ECM (PCM) uses it as one of the signals to control various devices.

DTC Detecting Condition And Trouble Area:

DTC CONFIRMATION PROCEDURE

WARNING:
- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and a tester, on a level road.

NOTE: Check to make sure that the following conditions are satisfied when using this "DTC CONFIRMATION PROCEDURE".
- Intake air temperature : between -14 °C and 70 °C (6.8 °F and 158 °F)
- Atmospheric pressure : higher than 560 mmHg (Altitude: lower than 2790 m (9150 ft))

1. With ignition switch OFF, connect scan tool.
2. Turn ON ignition switch and clear DTC by using scan tool if any.
3. Start engine and warm up to normal operating temperature.
4. Increase vehicle speed till engine speed is reached 4000 r/min. in 3rd gear (M/T) or 2nd range (A/T).
5. Release accelerator pedal and with engine brake applied, keep vehicle coasting and then stop vehicle.
6. Check DTC by using scan tool.
