Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the 
freeze frame data are stored. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs. 

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear 
command or by disconnecting the battery. 

DTC P2422 (117): ADVANCED DIAGNOSTICS 

DTC P2422: EVAPORATIVE EMISSION (EVAP) CANISTER VENT SHUT VALVE STUCK 
CLOSED MALFUNCTION

Fig. 242: Malfunction Judgement Flow Chart Of FTP Sensor And EVAP Canister Vent Shut Valve 

General Description 

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). The sensor indicates a negative pressure value (vacuum) during purging. 

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 engine control module 
(ECM)/powertrain control module (PCM) monitors the FTP sensor output after purge starts. The ECM/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 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 ECM/PCM 

stores the DTC of the Temporary DTC that was stored.

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

The output from the fuel tank pressure sensor is -4 kPa (-1.0 in.Hg, -25 mmHg)*, -2 kPa (-0.4 in.Hg, -10 
mmHg)** or less for at least 1.04*, 8** seconds. 

*: Elapsed time after the FTP sensor output exceeds the malfunction threshold.

Confirmation Procedure with the HDS 

Do the EVAP CVS ON in the INSPECTION MENU with the HDS. 

Driving Pattern 

Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan 
comes on, then let it idle.
