What is the difference between camshaft and crankshaft position sensor?
The crankshaft position sensor monitors as a multifunctional sensor used to set ignition timing, detect engine RPM and relative engine speed. The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.
What happens if the crankshaft sensor does not work?
If the crankshaft position sensor fails, it will not send information about the position of the crankshaft and speed of the engine RPMs to the ECU. As a result, the ECU doesn’t know when to send the spark plugs and how to adjust the fuel mixture. This can cause your car to stall or hesitate to start.
Where is the crankshaft position sensor on a Mercedes Benz?
Locate the crankshaft position sensor (CPS) on driver’s side, towards the rear of engine. Back of engine, near the firewall. This opens in a new window. Unplug the electrical connector from the CPS sensor. Squeeze the connector and pull it away from the CPS sensor. This opens in a new window. Remove bolt. Remove the crankshaft position sensor.
What are fault codes related to crankshaft position?
When the CPS is malfunctioning, the engine control module will trigger a fault code if it does not receive any signal from the CPS. Fault codes related to the crankshaft position sensor are: P0385, P0386, P0387, P0388 P0389 are related to B Circuit. P1336 usually related to a wiring problem, air gap, flywheel ring gear damaged, CPS sensor.
How much does it cost to replace the crankshaft position sensor?
Crankshaft Position Sensor Replacement Cost? While the prices vary based on your location the average cost of replacing the crankshaft position sensor at an auto mechanic or the Mercedes-Benz dealership vary between $250 and $400. The crankshaft position sensor cost between $100 and $150 at the dealership, that’s for the parts only.
What kind of sensor is on the crankshaft?
The crankshaft position sensor (CKP sensor or CPS) is one of several sensors that keep your engine running smoothly. It measures the position of the crankshaft (for which it is sometimes called the crank angle sensor or CAS), as well as the rotational speed of the crankshaft (for which it is sometimes called the engine speed sensor, ESS,
What happens if the crank position sensor fails?
Failed crankshaft position sensor can also impact the idling, the acceleration, or even your transmission shifting. In some cases, it can cause your transmission to go into limp mode. You may also notice an increase in engine vibrations. The check engine light is usually illuminated on your instrument cluster.
