SFI SYSTEM, Diagnostic DTC:P0336

DTC Code DTC Name
P0336 Crankshaft Position Sensor "A" Circuit Range / Performance

DESCRIPTION

The crank position sensor monitors the stop position and performs start control from the position of the stopped crankshaft. Moreover, the crankshaft position sensor contains a function which detects reverse rotation to correctly detect the stop position when the engine rotates reversely.

When a malfunction occurs in the reverse rotation detection function, stop and start system is disabled.

DTC No. DTC Detection Condition Trouble Area

CONFIRMATION DRIVING PATTERN


  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch to ON.

  3. Turn the tester on.

  4. Clear DTCs Click here.

  5. Turn the ignition switch off and wait for at least 30 seconds.

  6. Turn the ignition switch to ON and turn the tester on.

  7. Start the engine and wait for at least 20 seconds.

  8. Enter the following menus: Powertrain / Engine and ECT / DTC.

  9. Read pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  10. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  11. Input the DTC: P0336.

  12. Check the DTC judgment result.

    Tester Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • You should perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit

    Tech Tips

    If the judgment result shows INCOMPLETE or N/A, perform confirmation driving pattern again and then check the DTC judgment result.

CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. 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
