Conditions for Clearing the MIL/DTC

The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

DTC P0496

Step	Action	Values	Yes	No
Schematic Reference: Evaporative Emissions (EVAP) Hose Routing Diagram
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Start the engine. Seal the evaporative emission (EVAP) system using the Purge/Seal function with a scan tool. Observe the fuel tank pressure sensor with a scan tool. Is the fuel tank pressure sensor parameter within the specified range?	-1 to +1 in H2O	Go to Testing for Intermittent Conditions and Poor Connections	Go to Step 3
3	Turn OFF the ignition. Disconnect the EVAP purge pipe from the EVAP canister purge solenoid valve. Turn ON the ignition, with the engine OFF. Observe the fuel tank pressure sensor with a scan tool. Is the fuel tank pressure sensor parameter within the specified range?	-1 to +1 in H2O	Go to Step 4	Go to Step 5
4	Replace the EVAP canister purge solenoid valve. Did you complete the replacement?	-	Go to Step 6	-
5	Replace the fuel tank pressure (FTP) sensor. Refer to Fuel Tank Pressure Sensor Replacement . Did you complete the replacement?	-	Go to Step 6	-
6	Connect all EVAP hardware that was previously disconnected. Seal the EVAP system using the Purge/Seal function with a scan tool. Start the engine and idle. Observe the fuel tank pressure sensor parameter with a scan tool. Is the fuel tank pressure sensor parameter within the specified range?	-1 to +1 in H2O	Go to Step 7	Go to Step 2
7	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
