Note

P034000

Camshaft Position Sensor "A" Bank 1 or Single Sensor No Signal (sub)

No camshaft position sensor (for intake camshaft) signal to the sub ECM while engine running

ECM

Comes on

SAE: P0340

MONITOR DESCRIPTION

While the engine is running, when the VV1 (VV2) signal is not input to the sub CPU even though the VV1 (VV2) signal is input to the main CPU, the ECM judges that a malfunction has occurred in an internal ECM circuit, and illuminates the MIL and stores a DTC.

MONITOR STRATEGY

Required Sensors/Components (Main)

Camshaft position sensor

Required Sensors/Components (Related)

Crankshaft position sensor

Frequency of Operation

Continuous

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Turn the ignition switch to ON.
  7. Turn the GTS on.
  8. Start the engine.
  9. Idle the engine for 10 seconds or more.
  10. Enter the following menus: Powertrain / Engine / Trouble Codes.
  11. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  13. Input the DTC: P034000.
  14. Check the DTC judgment result.

    GTS Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1.

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P034000)

(a) Read the DTCs.

Powertrain > Engine > Trouble Codes

Result

Proceed to

P034000 is output

A

P034000 and other DTCs are output

B

HINT:

If any DTCs other than P034000 are output, troubleshoot those DTCs first.

A

REPLACE ECM
