Catalyst System Low Efficiency Bank 1

Trouble Code: P0442



Evaporative Emissions (EVAP) System Small Leak Detected

Possible Causes:



The EVAP system can be filled with smoke more quickly and completely by opening the system opposite the end where the smoke is injected. For example, when injecting smoke at the service port, remove the filler cap or temporarily leave the vent open until smoke is observed. Close the system and continue testing. If using a fuel cap adapter at the filler neck, use the J 41413-VLV at the service port to allow the system to fill faster.
 
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 .
 
To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT .
 
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 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 test them one at a time using the adapters in the J 41413-300 .
 

Trouble Code: P0443



Evaporative Emission (EVAP) Purge Solenoid Control Circuit

Trouble Code: P0446



Evaporative Emission (EVAP) Vent System Performance

Possible Causes:



An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent solenoid valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.
 
An EVAP canister that is restricted can cause this DTC to set.
 

Trouble Code: P0449



Evaporative Emission (EVAP) Vent Solenoid Control Circuit

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.
 

Trouble Code: P0452



Fuel Tank Pressure (FTP) Sensor Circuit Low Voltage
