COMMON RAIL PRESSURE, SENSOR










1. CHECK THE VOLTAGE BETWEEN TERMINALS.
1. Set the starter switch to "ON" (ECU connectors remain connected and the engine is stopped).
2. Measure the voltage between PCR1 (D20), PCR2 (D31) and AGD 1 (D33) of ECU connector (ECU side).

Standard: 0.7 - 4.7 V
(After measurement, turn the starter switch to "LOCK" position.)










2. CHECK THE VOLTAGE BETWEEN TERMINALS.
1. Disconnect the connector of common rail pressure sensor.
2. Measure the voltage between terminals of common rail pressure sensor (vehicle harness side).

Standard: 4.5 - 5.5 V










3. Turn the starter switch to "LOCK" position.
4. Disconnect the ECU connectors.
5. Measure the resistance between PCR (D20 and D31) terminals of ECU connector (vehicle harness side) and PCR terminal of common rail pressure sensor (vehicle harness side).

Standard: Less than 2 ohms










6. Turn the starter switch to "LOCK" position.
7. Disconnect the ECU connectors.
8. Measure the resistance between AVC2 (D24) terminals and PCR+ terminal of common rail pressure sensor (vehicle harness side), AGD1 (D33) terminal PCR- terminal of common rail pressure sensor (vehicle harness side).

Standard: Less than 2 ohms
