SFI SYSTEM, Diagnostic DTC:P0336

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

DESCRIPTION

The crankshaft 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.

Crankshaft Position Sensor "A" Circuit Range / Performance

When one of the following conditions is met (1 trip detection logic):

  • An engine reverse signal is detected for 4 seconds while the engine is cranking or running normally at 900 rpm or higher.

  • The pulse width of the crankshaft position sensor is detected to have exceeded the threshold for 4 seconds while the engine is running at 900 rpm or higher.

  • The input signal voltage of the crankshaft position sensor continues at 4.7 V for 4 seconds while the engine is running.

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • No. 1 crankshaft position sensor plate

MONITOR DESCRIPTION

When one of the following malfunctions is detected, P0336 is output.

  1. An engine reverse signal is detected for 4 seconds while the engine is cranking or runnning normally at 900 rpm or higher.

  2. The case the pulse width of the crankshaft position sensor is detected to have exceededthe threshold for 4 seconds while the engine is running normally at 900 rpm or higher.

  3. The input signal voltage of the crankshaft position sensor continues at 4.7 V for 4 seconds while the engine runnning.

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.

  2. Turn the ignition switch to ON and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

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

  5. Turn the ignition switch to ON and turn the GTS on.

  6. Start the engine.

  7. Idle the engine for 20 seconds or more.

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

  9. Read the pending DTCs.

    Tip:

    • 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.

    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

    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    Tip:

    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

Tip:

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 P0336)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
