That could give a clue to what the problem is. Knowing the codes could help in the diagnoses of the problem.

Vehicle Application: 2000 Chevrolet Suburban 1500 5.3L 2003 Chevrolet Avalanche 1500 5.3L, GAS, Vin T 2001 Chevrolet Silverado 1500 4.3L, Vin W, Eng Cfg V6 2003 Chevrolet Silverado 1500 5.3L, GAS, Vin T, Eng Cfg V8 2002 Chevrolet Silverado 1500 5.3L, GAS, Vin T, Eng Cfg V8 Customer Concern: Repeat P0446. The updated vent kit has been installed. Tests/Procedures: 1. Install the scan tool and monitor the fuel tank pressure sensor value to be approximately 1.5 volts and/or 0 inches of water vacuum (+-0.5" H2O). 2. Run the engine at a hot curb idle and view the purge solenoid command. Increase engine speed and the purge solenoid % will increase. 3. Verify the tank pressure sensor value does not go up (a slight increase of approximately 0.5 volts/1" H2O is normal). 4. If the value increases, disconnect the large hose on the canister (this is the vent hose). If the value drops, check for the filter to be plugged or incorrect vent assembly installation. 5. If the value continues to rise, replace the canister. Potential Causes: Canister Vapor Line Vent Vent Control Solenoid Tech Tips: Refer to bulletin #02-06-04-037D - (04/16/2008) for the updated vent kit information. Diagnostic Codes: P0446
