How is the CKP sensor used in the ECU?
The CKP sensor reacts to a toothed wheel on the crankshaft, generating a signal, which the ECU used to determine two very important data points – engine speed (RPM) and engine position, or cylinder #1 top dead center (TDC). Using this information, the ECU modulates all other engine functions. What are the common causes of code P0335 ?
What happens when crankshaft position sensor ( CKP ) fails?
If the sensor (CKP) has failed completely, then the computer won’t send any fuel to the injectors. Consequently, Leaving you unable to start the car. A Crankshaft Position Sensor (CKP) Failure may cause the check engine light on your dashboard to come on.
What does CKP stand for in engine control unit?
Regarding the most basic timing in an engine, the engine control unit (ECU) monitors the crankshaft position sensor, often abbreviated as CKP.
Can a knock sensor cause a car ECM to fail?
There’s also a knock sensor on the engine itself. While these sensors aren’t likely to cause any catastrophic problems, failures in these areas can cause your ECM to make unnecessary adjustments that affect your car’s performance. In these cases, though, the problem is usually with the sensors, and not with the ECM.
Where is the CKP sensor on a DTC car?
DTC P0335 Crankshaft Position (CKP) Sensor Circuit Circuit Description The Crankshaft Position Sensor CKP is mounted in the right rear of the engine block behind the starter. The CKP sensor works in conjunction with a 24X reluctor wheel mounted on the rear of the crankshaft.
What should the CKP sensor read on a crankshaft?
Touch the DMM red lead to the red (power) wire on the harness connector. You may need to check the wiring diagram for your particular model, if the CKP sensor uses wires of different color to identify the ground, power and signal wires. Turn the ignition key to the On position. Your meter should read between 5 and 13 volts.

When does the PCM determine no signal from the CKP sensor?
The PCM determines no signal from the CKP sensor for less than 3 seconds. Action Taken When the DTC Sets The PCM illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
