DTC P2420

DTC P2420  : Fuel Vapor Containment Valve Control Circuit High Voltage

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Turn the vehicle to the ON mode.

   -5. Select the EVAP TEST in the Function Test Menu, then select the Single Solenoid Test with the HDS.

   EVAP TEST

   -6. Select the Fuel Leak Detection Valve (CCV) in the Single Solenoid Test with the HDS.

   Is the result OK?

   YES 

   If the test result is PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the EVAP leak check module and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

   NO 

   The failure is duplicated. Go to step 2.

2. Shorted wire check (FCTV- line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Jump the SCS line with the HDS, and wait more than 1 minute.

   -3. Disconnect the following connector.

   PCM connector A (50P)

   Fuel vapor containment valve 2P connector

   -4. Turn the vehicle to the ON mode.

   -5. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   	PCM connector A (50P): disconnected
   	Fuel vapor containment valve 2P connector: disconnected
   Test point 1	Fuel vapor containment valve 2P connector (female terminals) No. 1:

   Is there battery voltage?

   YES 

   Repair a short to power in the FCTV- wire between the PCM (A15) and the fuel vapor containment valve.

   NO 

   The FCTV- wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
