Purge Flow Sensor: Testing and Inspection

Comp. Loc:

WARNING: Do not suck air through the EVAP Tank Pressure Control Solenoid Vacuum valve tubes/hoses. Fuel vapor inside the EVAP Tank Pressure Control Solenoid Vacuum valve is harmful.

Tool Required

^ J 39200 Digital Multimeter

1. Disconnect the EVAP Tank Pressure Control Solenoid vacuum valve electrical connector.
2. Using J 39200, measure resistance of the EVAP Tank Pressure Control Solenoid vacuum valve between both terminals. If resistance is not 28 to 36 ohms at 20°C (68°F), replace the EVAP Tank Pressure Control Solenoid vacuum valve. If the resistance is within specification, proceed with Step 3.
3. Disconnect the EVAP Tank Pressure Control Solenoid vacuum valve vacuum hoses from the intake manifold and the vacuum pipe (from Tank Pressure Control valve).
4. Blow air into the EVAP Tank Pressure Control Solenoid vacuum valve vacuum hose that was disconnected from the vacuum pipe. Air should not pass through the EVAP Tank Pressure Control Solenoid vacuum valve and exit from the intake manifold hose.
5. Connect 12 volts DC to the EVAP Tank Pressure Control Solenoid vacuum valve terminals.
6. Blow air into the EVAP Tank Pressure Control Solenoid vacuum valve vacuum hose that was disconnected from the vacuum pipe. Air should pass through the EVAP Tank Pressure Control Solenoid vacuum valve and exit from the intake manifold hose.

^ If the EVAP Tank Pressure Control Solenoid vacuum valve failed this inspection, replace it.
