DTC P0010: VTC Oil Control Solenoid Valve Malfunction

NOTE:  Before you troubleshoot, review the general troubleshooting information - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System (CVT) .

DTC (PGM-FI)

  1. Problem verification:

    - 1. Turn the vehicle to the ON mode.

    - 2. Clear the DTC with the HDS - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System (CVT) .

    - 3. Start the engine. Hold the engine speed at 3, 000 rpm without load (CVT in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.

    - 4. Select the VTC TEST in the INSPECTION MENU with the HDS.

    VTC TEST

    - 5. Check for Pending or Confirmed DTCs with the HDS.

    Is DTC P0010 indicated?

    YES 

    The failure is duplicated. Go to step 2.

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the VTC oil control solenoid valve and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

  2. VTC oil control solenoid valve internal resistance check:

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

    - 2. Disconnect the following connector.

    VTC oil control solenoid valve 2P connector

    - 3. At the VTC oil control solenoid valve side, measure the resistance between test points 1 and 2.

    Test point 1 VTC oil control solenoid valve 2P connector No. 1 (VTC oil control solenoid valve side)
    Test point 2 VTC oil control solenoid valve 2P connector No. 2 (VTC oil control solenoid valve side)

    Is there 6.75 - 8.25 Ω at room temperature?

    YES 

    Go to step 3.

    NO 

    Replace the VTC oil control solenoid valve .

  3. Open wire check (PG line):

    - 1. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VTC oil control solenoid valve 2P connector: disconnected
    Test point 1 VTC oil control solenoid valve 2P connector No. 2
    Test point 2 Body ground

    Is there continuity?

    YES 

    The PG wire is OK. Go to step 4.

    NO 

    Repair an open in the PG wire between the VTC oil control solenoid valve and the G101.

  4. Shorted wire check (VTC line):

    - 1. Jump the SCS line with the HDS.

    SCS Short

    - 2. Disconnect the following connector.

    PCM connector C (51P)

    - 3. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VTC oil control solenoid valve 2P connector: disconnected
      PCM connector C (51P): disconnected
    Test point 1 VTC oil control solenoid valve 2P connector No. 1
    Test point 2 Body ground

    Is there continuity?

    YES 

    Repair a short in the VTC wire between the VTC oil control solenoid valve and the PCM (C6).

    NO 

    The VTC wire is not shorted. Go to step 5.

  5. Open wire check (VTC line):

    - 1. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      VTC oil control solenoid valve 2P connector: disconnected
      PCM connector C (51P): disconnected
    Test point 1 VTC oil control solenoid valve 2P connector No. 1
    Test point 2 PCM connector C (51P) No. 6
    GHH80483Courtesy of HONDA, U.S.A., INC.

    Is there continuity?

    YES 

    The VTC wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If DTC P0010 goes away and the PCM was updated, troubleshooting is complete. If DTC P0010 goes away and the PCM was substituted, replace the original PCM .

    NO 

    Repair an open in the VTC wire between the VTC oil control solenoid valve and the PCM (C6).
