DTC P0335 Crankshaft Position Sensor "A" Circuit

DTC P0339 Crankshaft Position Sensor "A" Circuit Intermittent

DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate and pickup coil. The 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 sensor plate rotates, and a pulse signal is created as each tooth passes by the pickup coil. The pickup coil generates 34 signals for each revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the common rail system is controlled.

INSPECTION PROCEDURE

  • NOTICE:
After replacing the ECM, the new ECM needs registration () and initialization ().
After replacing the fuel supply pump assembly, the ECM needs initialization ().
After replacing an injector assembly, the ECM needs registration ().
  • HINT:
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.
The Data List item Engine Speed is calculated from the output of the crankshaft position sensor.
A DTC is also stored when the ground of a shielded wire is faulty.
1.INSPECT CRANKSHAFT POSITION SENSOR

Inspect the crankshaft position sensor ().
