Purge Control System

1. Disconnect the purge hose from the evaporative emission (EVAP) canister, and connect the special tool (purge flow indicator) between the EVAP canister and the purge hose.
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. Let the engine run at idle for at least four minutes.
4. Race the engine suddenly several times and check the purge flow rate.

Standard value: momentarily 20 cu.cm (2.5 SCFH) or more

5. If the purge flow rate is below the standard value, disconnect the vacuum hose from the EVAP canister, and check the purge flow rate again.

If the purge flow rate is below the standard value, check the vacuum port and hose for blockage, or the emission purge solenoid.

In addition, replace the EVAP canister when the purge flow rate is at the standard value.
