Recirculating valve for turbocharger, checking

Note: Valve opens between connection to intake manifold and connection to deceleration shutoff valve with no voltage. Connection to vacuum reservoir is closed.

Test sequence

- Switch ignition off.

- Disconnect connector from recirculating valve for turbocharger -N249-.






- Measure resistance between terminals of valve.

Specified value: 25 to 35 Ohms

If specified value is not obtained:

- Replace recirculating valve for turbocharger -N249-.

If specified values are obtained:

- Connect test box to control module wiring harness.






- Check wire between test box socket 105 & 2-pin connector terminal 2 for open circuit according to wiring diagram.

Wire resistance: max: 1.5 Ohms

- Also check the wire for short circuit to B+ and Ground (GND).

If no malfunctions are found in wire:

- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.

Wire resistance: max: 1.5 Ohms

If no malfunctions are found in wires:

- Replace Engine Control Module (ECM).
