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

DESCRIPTION

The crankshaft position sensor system consists of a crank angle sensor plate (crankshaft) and a pickup coil*1 or MRE (Magnet Resistance Element) type sensor*2. The crank angle sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed to the crankshaft.

The crankshaft position sensor generates 34 signals per crankshaft revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculated values, the fuel injection and ignition timing are controlled.

  • *1: w/o Stop and Start System

  • *2: w/ Stop and Start System

w/ Stop and Start System:

The crankshaft position sensor monitors the crankshaft position when the engine is stopped so that the engine can be restarted from the position that the crank was stopped. The crankshaft position sensor has a reverse rotation detection function, therefore the correct position of the crankshaft can be determined even if the crankshaft slightly rotates backwards. If the reverse rotation detection function malfunctions, stop and start control will be suspended.

DTC No.

CONFIRMATION DRIVING PATTERN

DTC P0335 and P0336 is detected when the engine cranks more than 20 revolutions.

CAUTION / NOTICE / HINT

Note:

  • After replacing the ECM, perform idle learning.

  • If any DTCs related to the crankshaft position sensor, throttle position sensor and accelerator pedal sensor assembly are output simultaneously, inspect the VC circuit of each component.

Tip:

  • 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 GTS. To perform the check, follow the procedures below:

    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / 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 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. READ VALUE USING GTS (ENGINE SPEED)

    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 / Data List / All Data / Engine Speed.

      Powertrain > Engine and ECT > Data List

      Tester Display

      Engine Speed

    5. Start the engine.

    6. Read the values displayed on the GTS while the engine is running.

      Standard

      Correct values are displayed.

      Tip:

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

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

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