СИСТЕМА ECD, Diagnostic DTC:P0335, P0336

DTC Code DTC Name
P0335 Crankshaft Position Sensor "A" Circuit
P0336 Crankshaft Position Sensor "A" Circuit Range / Performance

DESCRIPTION

The crankshaft position sensor is installed to the gearbox case.

The crankshaft position sensor records the position of the crankshaft with the aid of a sensor wheel screwed to the flywheel.

The ECM uses the signals to calculate the duration as well as the length of one crankshaft revolution.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0335 Crankshaft Position Sensor "A" Circuit

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Check the value on the GTS.


    1. Connect the GTS to the DLC3.

    2. Start the engine and turn the GTS on.

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

  • The engine speed can be confirmed in the Data List using the GTS. If there are no NE signals from the crankshaft position sensor despite the engine running, the engine speed will be indicated as zero. If the voltage output of the crankshaft position sensor is insufficient, the engine speed will be indicated as lower than the actual engine speed.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition 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, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)


    1. Disconnect the crankshaft position sensor connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      B225-2 (NE) - B220-121 (NE+) Always Below 1 Ω
      B225-3 (NE-) - B220-90 (NE-) Always Below 1 Ω
      B225-1 (VG) - B220-122 (VCNE) Always Below 1 Ω
      B225-2 (NE) or B220-121 (NE+) - Body ground Always 10 kΩ or higher
      B225-3 (NE-) or B220-90 (NE-) - Body ground Always 10 kΩ or higher
      B225-1 (VG) or B220-122 (VCNE) - Body ground Always 10 kΩ or higher
