P2422 2010 Honda Accord Code - Evaporative Emission System Vent Valve Stuck Closed
Quick Answer
The fuel tank pressure (FTP) sensor output indicates about atmospheric pressure 0 kPa (0 in.Hg, 0 mmHg) before purge starts since the evaporative emission (EVAP) canister vent shut valve is normally open (open to the atmosphere). Common causes include Faulty Evaporative Emission Vent Shut Valve, Evaporative Emission Vent Shut Valve harness is open or shorted, Evaporative Emission Vent Shut Valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2422 2010 Honda Accord Description
When the FTP sensor indicates vacuum after starting the engine, there is the possibility of an FTP sensor zero point shift failure or an EVAP canister vent shut valve stuck closed failure. So the Powertrain Control Module (PCM) monitors the FTP sensor output after purge starts. The PCM detects a malfunction of the EVAP canister vent shut valve if the output indicates excessive vacuum.
However, if the fuel tank internal pressure is below the specified value (excessive vacuum is detected) when starting the engine, the malfunction detection should be done as follows because it is difficult to distinguish the FTP sensor range problem (P1454) from the EVAP canister vent shut valve stuck closed (P2422).
1. If neither Temporary Diagnostic Trouble Code (DTC) (P1454 nor P2422) is stored, both DTCs are stored.
2. If both Temporary DTCs (P1454 and P2422) are stored and excessive vacuum is detected, both DTCs are stored.
3. If either Temporary DTC (P1454 or P2422) is stored and excessive vacuum is detected, the PCM stores the DTC of the Temporary DTC that was stored.
What are the Possible Causes of the DTC P2422 2010 Honda Accord?
- Faulty Evaporative Emission Vent Shut Valve
- Evaporative Emission Vent Shut Valve harness is open or shorted
- Evaporative Emission Vent Shut Valve circuit poor electrical connection
