Camshaft Position Sensor

Optimal engine control is based on prompt, exact information from the powertrain. The engine control unit (ECU) uses the camshaft position sensor to record the exact position of the camshaft. At FridayParts, you can explore an extensive selection of high-precision camshaft position sensors for vehicles of various brands like Ford, Nissan, Toyota, Kia, Sany, Mitsubishi, Volvo, Hyundai, John Deere, Kubota, CASE and more. Built to rigorous standards, our selection of cam position sensors offers immediate recording of the camshaft position for rapid valve control.

What Is A Camshaft Position Sensor?

A camshaft position sensor (cam sensor) detects the position of the camshaft. It sends this information to the engine control module (ECM). The ECM uses this data to control fuel injection timing, ignition timing, and the coil firing sequence.

How Does A Camshaft Position Sensor Work?

The cam sensor is a Hall effect sensor. It sits very close to a ring gear on the camshaft. As the camshaft rotates, the ring gear causes the sensor's voltage to change. The ECM reads these voltage changes to determine the camshaft's position and identify cylinder #1's top dead center (TDC). All engine timing is based on TDC. The cam sensor does not work alone. The ECM also uses data from the crankshaft position sensor, mass air flow sensor, and other sensors. Together, this data ensures fuel is injected and the spark plug fires at exactly the right moment.

What Happens When the Camshaft Position Sensor Fails?

A camshaft position sensor problems can affect a vehicle's engine timing or its ability to start at all. Once the cam position sensor fails, you may notice these signs of a bad camshaft position sensor:

• Rough idle
• Engine stalling
• Reduced power or slow acceleration
• Reduced gas mileage
• longer start times
• A complete failure to start

A bad camshaft position sensor may also trigger the Check Engine light to alert you to a problem. If a camshaft position sensor fails completely, it may stop sending any signal at all to your engine computer, and this may cause the vehicle to stop running and fail to start again. This can be dangerous if it happens while driving, leaving you stranded, so it's best to address signs of a camshaft position failure as soon as possible. FridayParts carries a vast selection of replacement camshaft position sensors and crankshaft sensors for most vehicles to help you start your diagnosis and complete your repair.

How to Replace a Camshaft Position Sensor?

Like other position sensors, changing the camshaft position sensor is typically a short, straightforward process. The biggest challenge is an accurate diagnosis. A new aftermarket camshaft position sensor ranges from $15 to $60 at FridayParts, depending on the vehicle you drive. At FridayParts, you’ll find the replacement parts to change your cam sensor. Find the right sensor for your application by filtering by the make, model, and engine size, then choosing from popular brands. Explore our extensive selection of position sensors and save today!
