EGR SOLENOID VALVE 1







1. CHECK THE VOLTAGE BETWEEN TERMINALS.







1. Set the starter switch to "LOCK" and connect the signal check harness.
2. Set the starter switch to "ON" position.
3. Measure the voltage between EGR1(D7) and PGD1(D1) terminals of ECU connector (vehicle harness side).

Standard: More than 10 V












2. CHECK THE RESISTANCE BETWEEN SOLENOID VALVE TERMINALS.
1. Set the starter switch to "LOCK" position.
2. Disconnect the connector of EGR valve 1.
3. Measure the resistance between EGV1 and EGR1 terminals of EGR valve 1 connector.

Standard: 25.5 - 29.5 ohms at 20 °C {68 °F}












3. CHECK THE RESISTANCE BETWEEN SOLENOID VALVE TERMINALS.
1. Set the starter switch to "LOCK" and disconnect the signal check harness connectors on ECU side.
2. Measure the resistance between EGR1 (D7) terminals of ECU connector (vehicle harness side) and EGR1 terminal of EGR valve1 (vehicle harness side).

Standard: Less than 1 ohm
