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 a 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.

Tech Tips

The correct waveform is as shown.
VV1+ stands for the camshaft position sensor signal, and NE+ stands for the crankshaft position sensor signal
Grounding failure of the shielded wire may cause noise in the waveforms.

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.

MONITOR STRATEGY

Required Sensors/Components (Main)	Crankshaft position sensor
Required Sensors/Components (Related)	Camshaft position sensor
Frequency of Operation	Continuous

COMPONENT OPERATING RANGE

Crankshaft position sensor

Crankshaft position sensor output voltage fluctuates while crankshaft revolving
34 crankshaft position sensor signals per crankshaft revolution

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON (IG) and turn the GTS on.
Put the engine in inspection mode (maintenance mode) Click here.
Start the engine.
Idle the engine for 20 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
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.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P0335.

Check the DTC judgment result.

GTS 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 the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

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

Connect the GTS to the DLC3.
Turn the ignition switch to ON (IG).
Turn the GTS on.
Put the engine in inspection mode (maintenance mode) Click here.
Start the engine.
Turn the GTS on.
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 the 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

READ VALUE USING GTS (ENGINE SPEED)
1. Connect the GTS to the DLC3.
2. Turn the ignition switch to ON (IG).
3. Turn the GTS 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 / All Data / Engine Speed.
7. Read the values displayed on the GTS while the engine is running.
  
  Standard
  
  Correct values are displayed.
  Tech Tips
  - 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 at zero (0), there may be an open or short in the crankshaft position sensor circuit.
