Diagnostic Aids
- Use the EVAP Pressure/Purge Diagnostic Station (J-41413) in order to pressurize the EVAP system to aid in locating intermittent leaks.
- A temporary blockage in the EVAP canister purge valve, purge pipe, or EVAP canister could cause an intermittent condition. Repair blockage in EVAP system.
- Reviewing the Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
