SFI SYSTEM, Diagnostic DTC:P0335

DTC Code DTC Name
P0335 Crankshaft Position Sensor "A" Circuit

DESCRIPTION

The crankshaft position sensor system consists of a crank angle sensor plate and a pickup coil.

The crank angle sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of wound copper wire, an iron core and magnet. The crank angle sensor plate rotates and, as each tooth passes by the pickup coil, a pulse signal is created. The pickup coil generates 34 signals per crankshaft revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the fuel injection and ignition timing are controlled.

DTC No. DTC Detection Condition Trouble Area
P0335

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


  • No crankshaft position sensor signal to ECM while engine running.

  • Missing crankshaft position sensor signal despite camshaft position sensor signal inputs normal after engine cranked.

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • Crankshaft (crank angle sensor plate)

  • ECM

MONITOR DESCRIPTION

If there is no signal from the crankshaft position sensor despite the crankshaft rotating, the ECM interprets this as a malfunction of the sensor.

CONFIRMATION DRIVING PATTERN


  1. Connect the Techstream to the DLC3.

  2. Turn the power switch on (IG) and turn the Techstream on.

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

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

  5. Turn the power switch on (IG) and turn the Techstream on.

  6. Put the engine in inspection mode (maintenance mode) Click here.

  7. Start the engine.

  8. Idle the engine for 20 seconds or more [A].

  9. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].

  10. Read the 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.

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

  12. Input the DTC: P0335.

  13. Check the DTC judgment result.

    Techstream 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
    N/A

    • Unable to perform DTC judgment

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

    Tech Tips


    • 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 steps [A] and [B] again.

  14. If no pending DTC is output, perform a universal trip and check for permanent DTCs Click here.

    Tech Tips


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

    • If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

Tech Tips


  • After performing the inspection procedure for the crankshaft position sensor, if DTC P0335 is output again, check the following items related to the camshaft position sensor.


    • Installation condition of the camshaft position sensor

    • Installation condition of the camshaft

    • Connection of the camshaft position sensor connector

  • If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.

  • The engine speed can be checked by using the Techstream. To perform the check, follow the procedures below:


    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the Techstream on.

    4. Put the engine in inspection mode (maintenance mode) Click here.

    5. Start the engine.

    6. Turn the Techstream on.

    7. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Engine Speed.


    • The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.

  • Read freeze frame data using the Techstream. 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. READ VALUE USING TECHSTREAM (ENGINE SPEED)


    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the Techstream on.

    4. Put the engine in inspection mode (maintenance mode) Click here.

    5. Start the engine.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Engine Speed.

    7. Read the values displayed on the Techstream while the engine is running.

      Standard
      Correct values are displayed.

      Tech Tips


      • To check the engine speed change, display the graph on the Techstream.

      • If the engine does not start, check the engine speed while cranking.

      • If the engine speed indicated on the Techstream remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.
