Trouble Code: P0451



Fuel Tank Pressure (FTP) Sensor Performance

Possible Causes:

P0451 and P0454



A restriction in the EVAP canister or vent lines could prevent fuel vapor pressure from bleeding off fast enough. If the vent system cannot bleed off pressure fast enough, the re-zero procedure may not complete successfully, which could cause this code to set.
 
Ensure that the reference port on the FTP sensor is unobstructed.
 
An FTP sensor that is skewed or does not have a linear transition from low to high may cause this code to set. Scan tool output controls, snapshot, and plot functions can help detect erratic sensor response. To test the sensor signal under vacuum conditions, use the Quick Snapshot and the Purge/Seal functions to capture data while commanding purge to 20 percent, then plot the data to look for erratic sensor operation. A similar test can be done for the pressure side of the sensor operation by applying pressure with the J 41413-200 while taking a snapshot.

Fuel Tank Pressure (FTP) Sensor Intermittent

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 .

Air Conditioning A/C Refrigerant Pressure Sensor Circuit High Voltage

Possible Causes:



A malfunction within the refrigerant system causing high pressure can cause this DTC to set.
 

Trouble Code: P0562



System Voltage Low - ECM

Trouble Code: P0563



System Voltage High

Possible Causes:



Observe the driver information center (DIC) messaging that would indicate the electrical system requires service.
 
Inspect for loose or damaged terminals at the generator.
 
Inspect for loose or worn generator drive belt.
 
Use the scan tool in order to inspect all other modules for voltage related DTCs.
 
Running the engine with a battery charger attached may cause DTC P0563 to set.
 
Inspect the charging circuit for high resistance.
 
Inspect the vehicle battery for open or sulfated cells.

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
