What can go wrong with a camshaft?

What can go wrong with a camshaft?

Poor Drivability. A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.

How are the crankshaft and camshafts held together?

Permanent magnet: creates an AC voltage signal that is proportional to engine speed. Hall Effect: uses a reference voltage from the PCM to produce a DC voltage signal. Inside the engine, the crankshaft and camshaft are held together by a timing belt or timing chain, which keeps them synchronized.

What can cause a cam / crank correlation problem?

Variable valve timing (VVT) system components can cause cam/crank correlation problems as well. These systems are often dependent on oil pressure, so checking the oil level is a good place to start. A plugged or failed oil control valve can also cause VVT problems.

What should I do if my crankshaft sensor is not working?

The most common solution to this code is the replacement/repair of wiring, followed by replacement of crankshaft/camshaft position sensors if the engine timing is known to be good. Less common solutions include replacement of reluctor rings, or VVT/VCT oil control solenoids. Note that PCM failures are rare.

How does the Camshaft Position Sensor ( CMP ) work?

The camshaft position sensor (CMP) is used to determine the position of the camshaft (s). It relays this information to the powertrain control module (PCM). The PCM then uses this information to control the fuel injectors, and on some applications, for ignition timing.

What’s the difference between a camshaft and crankshaft position sensor?

A lot of people confuse the camshaft position sensor with the crankshaft position sensor because they sound similar. But there’s a big difference between the two as they perform different functions in the vehicle and have different symptoms when something goes wrong with them.

Variable valve timing (VVT) system components can cause cam/crank correlation problems as well. These systems are often dependent on oil pressure, so checking the oil level is a good place to start. A plugged or failed oil control valve can also cause VVT problems.

How much does it cost to replace a camshaft sensor?

Camshaft Position Sensor Replacement Cost. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200. Labor costs will be in the range of $70 to $100 for professional replacement.

How to fix a bad camshaft position sensor?

Apply a bit of engine oil to the o-ring of the new senor. Install the new camshaft position sensor and secure with the mounting bolt. Reconnect the wire connector to the sensor. Reconnect the negative battery terminal.
