PURGE SOLENOID VALVE INSPECTION [L8, LF]
Evaporative Purge Control Inspection
Without using WDS or equivalent
1. Warm up the engine and idle it.
2. Disconnect the vacuum hose which is connected to the charcoal canister from purge solenoid valve.
3. Place your finger onto the purge solenoid valve
as shown in the figure and verify that vacuum is
applied.
If vacuum is not applied, inspect the following:
PCM output signal circuit (wiring harness,
connector)
Evaporative purge control signal
Purge solenoid valve
4. Run the vehicle on the chassis dynamometer and
maintain the engine speed at approx. 2,000 rpm.
5. Verify that vacuum is applied after approx. 30 s.
If the vacuum is not verified, inspect the
following:
PCM input signal circuit (sensor, switch, wiring harness)
Intake air temperature signal (intake air temperature sensor)
Evaporative purge control signal (purge solenoid valve)
Throttle opening signal (throttle position sensor)
Load/no load identification signal
/Transaxle range switch (ATX)
