How to tell
P0442Check engine / Service Engine Soon
What to do
- Connect the scan tool and command the EVAP system closed.
- Start the engine and watch the fuel tank pressure sensor value for about two minutes.
- If the tank pressure sensor value changes (shows vacuum), remove the purge solenoid and pressurize its fuel tank side with the GE 41413-A / J 41413-A tester.
- Add smoke and let the pressure stabilize; if smoke passes through the purge solenoid, replace the purge solenoid.
- If the sensor value does not change, install the CH-48096 adaptor between the purge line from the canister and the purge solenoid; use no other adaptor or pressurization method.
- With the EVAP system closed, pressurize through the CH 48096 adaptor and watch the pressure/vacuum gauge for at least 5 minutes until the system is fully stable, then add smoke.
What is needed
- Parts and materials
- Purge solenoid (if smoke is allowed to pass through the purge solenoid)
