EGR Valve Position Sensor: Testing and Inspection

Inspection of Electrical Equipment







#201 Inspection of relay (normally open, 5 pins)
- Perform a continuity check and an operation check. If there is any abnormality, replace the relay.







#529 Inspection of intake throttle
- Perform the following checks. If there is any abnormality, replace the throttle.

1. Coil resistance of motor
- Measure the resistance between terminals 5 and 6.

Standard value: 1.45 ± 0.21 ohms

2. Position sensor
- The sensor cannot easily be inspected in isolation, so you must evaluate it indirectly by inspection of system harnesses and related parts.
- If there is no abnormality in any related part but the system is abnormal, replace the intake throttle.







#530 Inspection of exhaust gas recirculation valve
- Perform the following checks. If there is any abnormality, replace the exhaust gas recirculation valve.

1. Coil resistance of motor
- Measure the resistance between terminals 8 and 7, the resistance between terminals 8 and 6, and the resistance between terminals 7 and 6.

Standard value: 2.1 ± 0.3 ohms

2. Position sensor
- The sensor cannot easily be inspected in isolation, so you must evaluate it indirectly by inspection of system harnesses and related parts.
- If there is no abnormality in any related part but the system is abnormal, replace the exhaust gas recirculation valve.
