Purge Control System

1. Disconnect the purge hose from the evaporative emission (EVAP) canister and connect the special tool (purge flow indicator) between the purge hose and the EVAP canister.
2. The vehicle should be prepared as follows before the inspection and adjustment.
- Engine coolant temperature: 80 - 95°C (176 - 203°F)
- Lights, cooling fan and accessories: OFF
- Transaxle: Neutral (A/T for P range)

3. Run the engine at idle for more than 4 minutes.
4. Quickly race the engine several times and check the purge flow rate.

Standard value: Temporarily becomes to 20 Cubic.cm/sec (2.5 SCFH) or higher.

5. If the measurement is less than the standard value, disconnect the vacuum hose from the EVAP canister and recheck the purge flow rate.
If the measurement is still below the standard value, check the vacuum port and the vacuum hose for clogging, and also check the evaporative emission purge solenoid for function.
If the measurement satisfies the standard value this time, replace the EVAP canister.
