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.

How to check for p2422 OBD-II trouble code?

Checks the fuel cap to ensure that it is properly affixed to the fuel inlet (the fuel cap should be tested with a fuel cap tester if available) Clears all trouble codes and completes a test drive to see if the P2422 trouble code comes back

What does p2422 mean on an EVAP system?

EVAP trouble codes that may be a symptom of the P2422 trouble code: The P2422 diagnostic trouble code is an indication that the vent valve of the evaporative emissions control system (EVAP) is stuck closed. The EVAP system reduces harmful pollutants, generated by the engine combustion process, from being expelled into the environment.

How much does it cost to repair a Honda p2422?

The cost to diagnose the P2422 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

Why is the canister shut shut on my Honda p2422?

The P2422 — EVAP canister vent shut valve stuck closed malfunction is caused by dirt accumulation in the EVAP charcoal canister vent tube. For more information on EVAP systems and how they work, see this post. Start by inspecting the canister vent tube for clogging from dirt and debris.

What does the OBD II fault code p2422 mean?

OBD II fault code P2422 is a generic code that is defined as “Evaporative emission (EVAP) vent valve – valve stuck closed”, and is set when the PCM (Powertrain Control Module) detects that the EVAP (Evaporative Emissions Control System) vent valve is stuck in the closed position.

What happens when the EVAP vent valve fails?

From the above it should be obvious that the EVAP vent valve is a critical component in the EVAP system, and should the PCM detect that the vent valve has failed, in the sense that it is stuck in the closed position, it will set code P2422 as a result.

What causes an EVAP canister to be stuck closed?

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.

What happens if the EVAP valve is stuck?

If the EVAP vent valve is stuck in the closed position, fuel vapors will be prevented from flowing through the vent valve and into the engine. The powertrain control module (PCM) receives a voltage signal from the vent valve control circuit. This voltage signal carries information regarding the pressure and flow of the EVAP system.
