What is a camshaft position sensor?

The camshaft position sensor is located adjacent to the engine camshaft, and relays information about the camshaft’s position of rotation at all times.

How does the camshaft position sensor work?

As the camshaft spins, the camshaft position sensor magnetically reads the camshaft position from a fixed location beside the shaft. This information is always being sent to the engine computer for comparison with data from the crankshaft position sensor. When the two signals reach the computer, they must match for the computer to understand there are no mechanical errors in the engine. If the position of the crankshaft is different than the position of the camshaft, the computer will record that an engine timing problem is occurring, and adjust settings as designed to protect the engine.

What are the symptoms related to a bad camshaft position sensor?

When the computer senses the engine is out of time, the check engine light will be displayed, and the engine may start and stall, or fail to start. Some models may prevent the ignition from attempting to start the engine. If the engine runs, it will experience loss of power, poor fuel mileage, restricted performance for engine and transmission, hesitation before accelerating and intermittent stalling. Lastly, OBD trouble codes will be stored for the crankshaft and camshaft position.

Can I drive with a camshaft position sensor problem?

Driving a vehicle with a failed camshaft or crankshaft position sensor is most often impossible, but even if driving is possible it is not recommended. If the sensor is functioning normally the engine may be out of time, or may have suffered mechanical failure.

Camshaft Position Sensor Replacement Repair Information

How are camshaft position sensor issues diagnosed?

When the vehicle is connected to a professional grade scanner, the position of the crankshaft and camshaft are read, and compared to actual engine position. If the reading is inconsistent for camshaft or crankshaft sensor, the sensor will be tested, and replaced if necessary.

How is a camshaft position sensor replaced?

Replacement of the camshaft position sensor is completed by disconnecting any electrical connector, and unscrewing the sensor. If required, sealant will be applied before re-inserting the new sensor into the engine. Finally the electrical connector is connected, and the vehicle is tested to confirm the repair.

RepairPal Recommendations for camshaft position sensor issues

OEM quality sensors should be used as lesser products will likely cause a repeated repair. Also, the vehicle's timing belt should be inspected if crankshaft position or camshaft position trouble codes are stored. If the timing belt or timing chain has failed, the engine should be immediately placed out of service.

What to look out for when dealing with camshaft position sensor issues

OBD trouble codes related to the crankshaft and camshaft do not imply faulty sensors, but imply a fault in the engine. This can be narrowed down to the sensors, but replacing the sensor without testing may lead to unnecessary costs.

Can I replace the camshaft position sensor myself?

Replacing a sensor is only a DIY capable project if the issue can be positively diagnosed at home. If the issue cannot be diagnosed at home, a technician should be trusted with the issue before changing parts leads to excessive repair bills without a solution.
