How does the camshaft position sensor work on a 4 cylinder engine?
By using the signals of the two sensors (crankshaft position and camshaft position), the injection computer can determine which piston is on the intake stroke and which is on the exhaust stroke (in the case of a 4-cylinder in-line engine. The crankshaft position sensor detects when the pistons are at BDC (eg 1 and 4).
How much does a bad camshaft sensor cost?
In this case, because of an inaccurate reading from a bad camshaft position sensor, more fuel than necessary is injected into the engine which causes your fuel economy to drop. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200.
How does the crankshaft position sensor work?
The crankshaft position sensor detects when the pistons are at BDC (eg 1 and 4). Then, with the position signal from the camshaft (positive or null), determine which of the two pistons is on the compression stroke.
Where is the camshaft positioning sensor located?
The Camshaft Position (CMP) Sensor is located in the right side of the engine compartment at the rear of the valve cover, near the intake manifold.
How much does it cost to replace camshaft position sensor?
Additional costs will be for the other engine parts that will support the camshaft and engine. A camshaft position sensor, which may be needed or replaced, can can cost $100 to $350 for the part.
What is the purpose of camshaft position sensor?
The camshaft position sensor is a crucial part of the engine management which ensures that the engine runs smoothly. The sensor is responsible for collecting information about the car’s camshaft speed and send it to the Engine Control Module (ECM).
How do you test cam position sensor?
To test the camshaft position sensor, you need a multimeter and a magnet. Connect the sensor to a multimeter and set it to diode or low-resistance function. Use the magnet and pass it in front of the sensor several times.
What are the symptoms of a bad camshaft position sensor?
Symptoms of a Bad or Failing Camshaft Position Sensor. $79.99 – $89.99. Average rating from 4,829 customers who received a Check Engine Light is on Inspection. The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM).
What should the voltage be on a camshaft sensor?
After these checks, use a digital multimeter that can test either alternate current (AC) voltage or direct current (DC) voltage, depending on your particular type of camshaft position sensor. You’ll also need the correct electrical values for your particular type of sensor. You may find this information in your vehicle repair manual.
What does no spark on camshaft sensor mean?
No spark means that the engine will not start at all, indicating that the camshaft sensor has failed. Newer cars will detect that the camshaft position sensor is not functioning properly, then they will use the crankshaft position sensor instead.
How does the camshaft position sensor work on a car?
The camshaft position sensor calculates the speed at which the engine’s camshaft rotates. It also keeps track of the shaft’s precise position during rotation. It signals the PCM, which uses the sensor data to set the timing for the ignition and fuel injection systems.
What are the symptoms of a bad camshaft sensor?
7 Symptoms of a Bad Camshaft Position Sensor (and Replacement Cost) 1 Check Engine Light Illuminates. 2 Ignition Problems. 3 Car Jerking or Surging. 4 Engine Stalling. 5 Poor Acceleration. 6 Problems Shifting. 7 Bad Fuel Mileage.

What is the OTC camshaft sensor synchronizer tool for?
OTC’s Ford and Mercury Camshaft Sensor Synchronizer Tool is a ‘must have’ for ensuring correct installation of the cam sensor housing. Correctly aligns shaft and housing for insertion into engine once engine has been rotated to top dead center on the no. 1 cylinder’s compression stroke.
What to do if your camshaft sensor is dirty?
If the car has the above symptoms, do NOT drive the car anymore, you risk ruining more parts, even quite expensive parts such as the catalytic converter. In most cases, the camshaft sensor is only dirty when the car starts to show the above symptoms. Below are some steps you can take to clean the camshaft sensor.
How to replace camshaft position sensor for Mercedes Benz?
A single E8 Torx holds the intake and exhaust sensors in place. With the bolt removed you can pull the sensor from the head. With the sensor removed check that the mounting surface is clean and flat (red arrow) as well as have a look inside the port to make sure there is nothing that is blocking the magnet from sensing the cam.

What should I do if my camshaft sensor fails?
Avoid engine sputtering and-at worst-getting stuck on the side of the road by investing in one of the quality camshaft position sensors that we stock at AutoZone. All that horsepower underneath the hood isn’t going to help your vehicle if your cam position sensor fails.
Where do you put the number on a camshaft?
This number should be on your camshaft, followed by a number of degrees. For example, you might have a camshaft stamped with the numbers 899C, followed by various numbers with degrees. Take the 899C and add it to the model prefix.
