What is the function of the camshaft position sensor?
Camshaft Position Sensor Symptoms, Function & Location. 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).
Where is the camshaft sensor located on a Ford 3.0L engine?
On 3.0L engines, install camshaft synchronizer so that drive gear engagement occurs when arrow on Syncro Positioning Tool T95T-12200-A is pointed approximately 75 degrees (3.0L), 60 degrees (4.0L) counterclockwise off the centerline of the engine. This step will locate camshaft position sensor electrical connector to the original position.
Can a bad camshaft sensor shut down an engine?
Without this information, the engine would not be able to function properly. Over time, the camshaft position sensor can fail, or become worn down, due to accidents or normal wear and tear. There are a few warning signs to watch out for before your camshaft position sensor completely fails and shuts down the engine, making replacement a necessity.
What is the distributor stator or camshaft position sensor?
On 2 wire Sensor engines, the distributor stator or Camshaft Position (CMP) sensor is a single Hall effect magnetic switch. This is activated by a single vane, and is driven by the camshaft.
What are the symptoms of a bad camshaft position sensor?
The engine may stall intermittently. You may notice poor engine performance including irregular acceleration, misfiring, hard starting, or surging. On some car models, a failed CMP sensor will prevent the ignition from making a spark, so that the engine won’t start at all.
Where is the cam sensor on a Chevy?
The cam sensor (camshaft position sensor) is located inside the distributor on your Chevy (or GMC or Isuzu or Olds or Cadillac) mini-van or pick up or SUV. And as I mentioned at the beginning of the article the cam sensor test is done with a multimeter in Volts DC mode.
What is the camshaft position ( CMP ) sensor performance?
– P0341 Camshaft Position (CMP) Sensor Performance. Your GM mini-van, pick up, or SUV gas mileage is going thru’ the roof (in a negative manner-o’-speaking that is). Your GM mini-van, pick up or SUV idles rough. Hard start (starts after an extended amount of cranking time).
Where is the cam sensor located in the distributor?
The camshaft position (CMP) sensor is a three wire Hall Effect type sensor that needs power and ground to produce a Signal. The cam sensor is located within the distributor assembly and as such, it’s rotated by the camshaft.
How does the Hall principle work on a camshaft sensor?
The Hall principle is the core working concept of a camshaft sensor. A ring gear on the camshaft is scanned, and the rotation of the ring gear causes a change in the voltage of the Hall IC located in the sensor head. This induces a change in the voltage transmission of the control unit.
How do you align the holes in a camshaft?
Using SST, align the holes of the camshaft main gear and sub gear by turning the camshaft sub gear counterclockwise, and temporarily install a service bolt. Align the gear teeth of the main gear and sub gear, and tighten the service bolt.
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.
Camshaft Position Sensor Symptoms, Function & Location. 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).
Can a camshaft sensor be swapped with timing gear?
The camshaft position sensor on your engine will only work with the corresponding cam gear from the same year. To swap sprockets or sensors, you must swap both the camshaft timing gear and camshaft position sensor.
The Hall principle is the core working concept of a camshaft sensor. A ring gear on the camshaft is scanned, and the rotation of the ring gear causes a change in the voltage of the Hall IC located in the sensor head. This induces a change in the voltage transmission of the control unit.

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.
What does a bad camshaft sensor do?
At low speeds a bad camshaft sensor will cause the car’s engine to stall. The engine may also experience an inability to turn over, resulting in the car not starting.
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 does a cam position sensor do?
The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.
What does a camshaft positioning Sencor do?
The camshaft position sensor works in tandem with the crankshaft position sensor to monitor the engine’s timing which, in turn, affects the efficiency of fuel delivery and the sparking mechanisms. The camshaft position sensor is typically referred to as a CMP; the crankshaft position sensor is typically referred to as a CKP.
Can a bad camshaft sensor affect engine performance?
Since the engine uses the readings from both the crankshaft and camshaft sensors, a malfunction of either sensor could affect your engine’s readings and performance. The camshaft sensor is always operational when you are driving the car, or the engine is running.
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.
