Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

A faulty EVAP canister can cause a DTC P0441 and P0455 to set. The EVAP canister fault may be temperature sensitive. Test the EVAP canister when the canister temperature is similar to the temperature when the diagnostic failed. Refer to Evaporative Emission (EVAP) Control System Diagnosis .
In order to help locate intermittent leaks, use the J 41413-200 Evaporative Emissions System Tester (EEST) to introduce smoke into the EVAP system. See Special Tools . Move all EVAP components while observing smoke with the J 41413-SPT High Intensity Lamp. See Special Tools .
A temporary blockage in the EVAP purge solenoid, purge pipe or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system.
In order to improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT . See Special Tools .
Reviewing the Freeze Frame 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.
For intermittent conditions, refer to Intermittent Conditions .
