STOP AND START SYSTEM, Diagnostic DTC:P0335

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

DESCRIPTION

The crank position sensor sends an engine speed signal (NE signal) to the ECM. The engine speed signal is then sent directly from the NEO terminal of the ECM to the engine stop and start ECU. Additionally, the ECM sends the engine speed to the engine stop and start ECU via CAN communication. The engine stop and start ECU compares the NE signal and engine speed received via CAN communication to check for errors in the NE signal.

If the NE signal is abnormal, the engine stop and start ECU will blink the stop and start cancel indicator light and stores DTC P0335.

DTC No. DTC Detection Condition Trouble Area
P0335

All of the following conditions continue for 10 seconds (2 trip detection logic):


  • Normal communication between the ECM and the engine stop and start ECU.

  • Engine speed (NE signal) is below 6000 rpm.

  • Difference between the NE signal that is sent directly from ECM and the engine speed that is sent via CAN is 200 rpm or higher.

Both of the following conditions continue for 2 seconds or more (1 trip detection logic):


  • Starter is operating.

  • No NE signal input.

  • Wire harness or connector

  • Crankshaft position sensor

  • ECM

  • Engine stop and start ECU

Tech Tips

DTCs for the stop and start system are not cleared even if the malfunction has been repaired. After repairing the malfunction, be sure to clear the DTCs Click here.


  1. After troubleshooting, perform the following steps to recheck for DTCs.

    Tech Tips


    • When the cable is disconnected from the negative (-) battery terminal, stop and start control is prohibited for a certain amount of time. After connecting the cable, drive the vehicle until stop and start control is permitted (approximately 15 to 40 minutes).

    • Allow the engine to idle for 3 minutes after the engine warms up and check that the engine speed is within 50 rpm of the target idle speed.


    1. Connect the GTS to the DLC3.

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

    3. Clear the DTCs Click here.

    4. Start the engine and wait for at least 15 seconds.

    5. Check that no DTCs are output Click here.

  2. Check if the stop and start system operates normally.

    Tech Tips

    If the cable is disconnected from the negative (-) battery terminal, stop and start control is prohibited until refresh charge is completed. After connecting the cable, drive the vehicle until refresh charge is completed and stop and start control is permitted (approximately 15 to 40 minutes).


    1. for Manual transaxle


      1. Start the engine and warm it up.

      2. Turn the air conditioning system off.

      3. Drive the vehicle at 7 km/h (4.3 mph) or more.

        CAUTION:

        When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      4. Stop the vehicle, move the shift lever to neutral and release the clutch pedal.

      5. Allow the engine to stop by stop and start control.

      6. Depress the clutch pedal and start the engine.

    2. for CVT


      1. Start the engine and warm it up.

      2. Turn the air conditioning system off.

      3. Drive the vehicle at 7 km/h (4.3 mph) or more.

        CAUTION:

        When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      4. Depress the brake pedal and stop the vehicle.

      5. Keep the engine stopped by stop and start control for 1 second or more (Keep the shift lever in D).

      6. Release the brake pedal with the shift lever in D to start the engine.

Note


  • Before replacing the engine stop and start ECU, read the number of starter operations and write it into a new engine stop and start ECU Click here.

  • After replacing the engine stop and start ECU or air conditioning amplifier assembly, reset and perform learning of the air conditioning information in the engine stop and start ECU Click here.

  • After replacing the engine stop and start ECU or airbag sensor assembly, clear and calibrate the deceleration sensor zero point in the engine stop and start ECU Click here.

Tech Tips

Using the GTS, read the freeze frame data before troubleshooting. System condition information is recorded as freeze frame data the moment a DTC is stored. This information can be useful when troubleshooting Click here.

PROCEDURE


  1. CHECK FOR DTC (SFI SYSTEM)


    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.

    5. Read the DTCs
