INSPECTION
EVAP CANISTER PURGE SOLENOID VALVE
The EVAP Canister Purge Solenoid Valve is controlled by the ECM; when the engine coolant temperature is low, and also during idling, the valve closes so that evaporated fuel is not drawn into the surge tank. After engine warm-up during ordinary driving, it opens to let the stored vapors flow into the surge tank. When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to its original position.
1. | Disconnect the vacuum hose(black with red stripe) from the solenoid valve.
2. | Detach the harness connector.
3. | Connect a vacuum pump to the nipple to which the red-striped vacuum hose was connected.
4. | Apply vacuum and check when voltage is applied to the EVAP Canister Purge Solenoid Valve and when the voltage is discontinued.
Battery voltage | Normal condition
When applied | Vacuum is released
When discontinued | Vacuum is maintained
5. | Measure the current between the terminals of the solenoid valve.
EVAP Canister Purge Solenoid Valve Coil at 20°C (68°F) : 0.45A or below (at 12V) Coil resistance : 26Ω [at 20°C (68°F)]
VACUUM HOSE Engine coolant temperature : 80~95°C (176~205°F)
1. | Disconnect the vacuum hose from the intake manifold purge hose nipple and connect a hand vacuum pump to the nipple.
2. | Start the engine and check that, after raising the engine speed by racing the engine, vacuum remains fairly constant.
If there is no vacuum created the intake manifold port may be clogged and require cleaning.
