What is CMP or CKP mean?

What is CMP or CKP mean?

Camshaft Position Sensor (CMP) Crankshaft Position Sensor (CKP)

What is a CKP signal?

Crankshaft position sensor (CKP) is an electromagnetic sensor by the help of which the fuel injection system makes synchronization of the fuel injectors operation and the ignition system. СКР sensor sends signal for the speed and the position of the crankshaft to the onboard controller.

What is CMP sensor signal?

A CMP sensor signals one or more fixed camshaft reference positions to the Engine Control Module (ECM), for example, the arrival of a cylinder’s intake stroke. The ECM uses the camshaft sensor signal for accurate timing control of ignition (if a gasoline engine), injection, and variable valve phasing, etc.

What is CMP on a car?

Camshaft Position Sensor (CMP)

What can cause a P0340 code?

P0340 Causes

• A defective camshaft position sensor.
• Damaged or dirty reluctor ring on the camshaft.
• Defective, corroded, shorted camshaft position sensor circuit wiring.
• Defective, corroded, shorted camshaft position sensor circuit connector.
• A faulty crankshaft position sensor.
• Stretched or misaligned timing components.

Where is the CKP sensor located?

Sensor Location The (CKP) sensor will be located at the lower section of the engine block. It can either be at the front; rear or middle of the engine at the crankshaft level.

How do you test a CMP sensor?

Touch one of your meter probes to either one of the sensor wires and the other to the other wire. Check your meter display and compare your reading to your manual specifications. In most cases, you’ll see a fluctuating signal between 0.3 volts and 1 volt. If there’s no signal, you have a bad sensor.

What causes code P1391?

P1391 is an error code predominantly referring to an issue with either your Camshaft Position (CMP) Sensor, Crankshaft Position (CKP) Sensor, or both….What the P1391 Code Means.
