IMT (Intake Manifold Tuning) Vacuum Solenoid Valve On-Vehicle Inspection

WARNING:

If vacuum is applied using your mouth, there is a risk of inhaling harmful fuel vapor.

Be sure to use a hand vacuum pump to apply vacuum.

NOTE:

If too high a vacuum is applied, the IMT vacuum solenoid valve may be damaged.

Do not exceed a vacuum of -86 kPa (-12.47 psi).

1) Prepare to operate IMT vacuum solenoid valve as follows.
a) Connect special tool (ECM check harness) between ECM and ECM connector. Pinout Values and Diagnostic Parameters

NOTE:
Operate IMT vacuum solenoid valve using service wire as follows.
- IMT vacuum solenoid valve OFF: Disconnect service wire to "C37-42" terminal from vehicle body ground [a]
- IMT vacuum solenoid valve ON:
Connect service wire to "C37-42" terminal to vehicle body ground [b]





2) Disconnect vacuum hose No.1 (1) from vacuum tank and vacuum hose No.2 from IMT vacuum solenoid valve (2).
3) Install special tool to vacuum hose No.1 (1).

4) Check that IMT vacuum solenoid valve (2) operates as follows.

If faulty condition is found, check the following.
- Wire harness and connections
- IMT vacuum solenoid valve
- Vacuum hoses
a) Operate the special tool and check that vacuum of -60 kPa (-0.6 kgf/cm2, -8.7 psi, -0.6 bar) can be applied when IMT vacuum solenoid valve is turned OFF [A].
b) Operate the special tool and check that no vacuum can be applied when IMT vacuum solenoid valve is turned ON [B].
