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.
