1.CHECK HARNESS BETWEEN ECM AND EGR CONTROL VALVE CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

3) Disconnect the connector from the EGR control valve.

4) Turn the ignition switch to ON.

5) Measure the voltage between ECM connector and chassis ground.

Connector & terminal

DTC P1493; (B136) No. 11 (+) — Chassis ground (−):

DTC P1495; (B136) No. 13 (+) — Chassis ground (−):

DTC P1497; (B136) No. 31 (+) — Chassis ground (−):

DTC P1499; (B136) No. 32 (+) — Chassis ground (−):

Is the voltage 10 V or more?

Repair the short circuit to power supply in the harness between the ECM connector and EGR control valve connector.
