DTC P0335 CRANKSHAFT POSITION SENSOR (POS) - Component Description / ECM Terminals and Reference Value
EF & EC-7176spec tableComponent Description
The crankshaft position sensor is located on the transmission case in relation to the signal plate on the No. 6 counterweight.
The crankshaft position sensor is a basic component of the engine control system. It monitors engine speed, piston position, and fluctuation of the engine revolution. These input signals to the engine control system are used to control fuel injection, ignition timing and other functions.
The sensor consists of a permanent magnet, core and coil.
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change.
The signal plate is provided with 8 teeth to emit a signal at an interval of 6 deg during crankshaft operations. However, it is not provided with 2 teeth to emit a signal at an interval of 360 deg.
The changing gap causes the magnetic field near the sensor to change.
Due to the changing magnetic field, the voltage from the sensor changes.
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a grond other than ECM terminals, such as the ground.
