P1532

V : P1532. IMT VALVE 2

V1 : CHECK THE POWER SUPPLY CIRCUIT TO THE IMT VALVE 2

1. Turn the ignition switch to the ON position.
2. Measure the voltage between IMT valve 2 electrical connector EN998 pin 1 (NG) and GROUND.

Is the voltage greater than 10 volts?
Yes
Goto V2

No
REPAIR the circuit between the IMT valve 2 electrical connector EN998 pin 1 (NG) and the Battery power bus 2. CLEAR the DTC. TEST the system for normal operation.
This circuit includes the power distribution fuse box and the EMS control relay. For additional information, refer to wiring diagrams

V2 : CHECK CONTINUITY OF THE IMT VALVE 2 SIGNAL WIRE

1. Disconnect the PCM electrical connector EN16.
2. Measure the resistance between the IMT valve 2 electrical connector EN998 pin 2 (OY) and the PCM electrical connector EN16 pin 39 (OY).

Is the resistance less than 5 ohms?
Yes
Goto V3

No
REPAIR the circuit between the IMT valve 2 electrical connector EN998 pin 2 (OY)and the PCM electrical connector EN16 pin 39 (OY). For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

V3 : CHECK IMT VALVE SIGNAL WIRE FOR SHORT TO GROUND

1. Measure the resistance between EN998 pin 2 (OY) and GROUND.

Is the resistance less than 10,000 ohms?
Yes
REPAIR the short to GROUND. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
No
Goto V4

V4 : CHECK IMT VALVE SIGNAL WIRE FOR SHORT TO BATTERY

1. Connect the PCM electrical connector EN16.
2. Turn the ignition switch to the ON position.
3. Check for a voltage at EN998 pin 2 (OY).

Is the voltage greater than 10 volts?
Yes
REPAIR the short to battery. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
INSTALL a new IMT valve. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, INSTALL a new PCM. Before replacing a PCM, contact Dealer technical support.
