Symptoms of crankshaft sensor failure, what are the symptoms when the crankshaft sensor is broken?

The car itself is made up of many components, and even a small damage can be felt while driving. Today, the component we are going to talk about is the crankshaft sensor. The crankshaft position sensor is a very critical part of the electronic fuel injection engine control system. If the crankshaft position sensor fails, it will affect the normal operation of the vehicle. So, what are the symptoms of crankshaft position sensor failure? What are the manifestations of crankshaft sensor failure? Let's find out!

Symptoms of crankshaft sensor failure

The crankshaft position sensor plays a crucial role among sensors; it can determine the position of the crankshaft, detect engine speed, and also detect various signals including those used to control ignition at top dead center for each cylinder and those used for controlling sequential fuel injection at top dead center for cylinder one. The crankshaft position sensor usually works in conjunction with the camshaft position sensor to determine the basic ignition timing.

The typical manifestation of a crankshaft position sensor failure is that it will affect the normal starting of the engine or cause it to stall automatically when starting.

Symptoms of crankshaft sensor failure

1. Fault indicator light illuminated

2. The engine can continue to operate relying on the camshaft position sensor, but starting time may be longer, and cruise control and exhaust braking systems may not function properly. There may also be engine shaking and white smoke, but power performance does not change significantly, and throttle response is normal.

3. Possible fault codes:

(1) P0335 Crankshaft signal error - signal loss

(2) P0336 Crankshaft signal error - signal error

(3) P0008 Only camshaft signal working mode

Fault mode: ECU determines that there is a fault in the crankshaft position sensor signal

1. Sensor damage or contamination.

2. Signal line damage (open circuit or short circuit).

3. Installation phase or gap abnormality.

4. Signal disk abnormality.
