Trouble Code: P0455



Evaporative Emission (EVAP) System Large Leak

Possible Causes:



Inspect for a loose, missing, incorrect, or damaged fuel fill cap.
 
Verify that the fuel filler neck sealing surface is not distorted or damaged.
 
To help locate intermittent leaks, use the J 41413-200 to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT .
 
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.
 
A condition may exist where a leak in the EVAP system only exists under a vacuum condition. By using the scan tool Purge/Seal function to create a vacuum, seal the system and observe the FTP parameter for the vacuum decay, this type of leak may be detected.
 
If a small leak is difficult to find, it may be necessary to remove the EVAP components and leak test them one at a time using the adapters in the J 41413-300 .

5-Volt Reference 1 Circuit

Possible Causes:



It may be possible to locate the fault by disconnecting one component at a time from the 5-volt reference circuit while viewing the 5-Volt Reference circuit parameter on the scan tool. The scan tool parameter would change from Fault to OK when the source of the fault is disconnected. If all 5-volt reference components have been disconnected and a Fault is still indicated, the fault may exist in the wiring harness.
 

Trouble Code: P0650



Malfunction Indicator Lamp (MIL) Control Circuit

Trouble Code: P0651



5-Volt Reference 2 Circuit

Possible Causes:



It may be possible to locate the fault by disconnecting one component at a time from the 5-volt reference circuit while viewing the 5-Volt Reference circuit parameter on the scan tool. The scan tool parameter would change from Fault to OK when the source of the fault is disconnected. If all 5-volt reference components have been disconnected and a Fault is still indicated, the fault may exist in the wiring harness.
