How do you reset a camshaft position sensor?
Unfortunately, there's no way to reset a camshaft position sensor. If you're having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you'll have to replace the part entirely.
How do you test a camshaft position sensor?
Set your multimeter to Ohms and touch your meter leads to the sensor terminal pins. If there is infinite resistance, the sensor is open and you need to replace it. On some models, you'll get a resistance value between 200 and 900 ohms. Consult your repair manual specifications.
What does a camshaft position sensor do?
The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.

Why is my camshaft sensor bad?
For this reason, the camshaft sensor can become poor over time. Sometimes it is also damaged by oil leaks and cracks. The ring gear may also wear out and interfere with the readings.
What happens if you have a bad camshaft sensor?
One of the most common problems that occur due to a poor camshaft position sensor is that the engine’s power drops dramatically. You will notice frequent stalling, idling, and a drop in engine speed. Fuel efficiency also decreases. All these problems should be addressed immediately, and they usually occur because of a damaged camshaft position ...
What is a Camshaft Position Sensor?
Its purpose is to determine the position of the camshaft drive very precisely. As a result, it generates signals in the same way as the crankshaft position sensor. It helps the engine determine the exact time the first cylinder is in the top dead center position.

What does it mean when your engine has no spark?
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.
Why does my engine go into limp mode?
This is most often because the engine can go into Limp mode when you have a broken camshaft position sensor.
Why does my camshaft sensor fail?
Answer: Contamination from oil, moister or oil, vibration, can cause a camshaft sensor to fail prematurely. Check the mounting area for signs of contamination and make sure the unit is properly secure. Also, check for wiring damage. This may also cause a bad effect on the sensor itself.
Where is the camshaft position sensor located?
On most models you can find the sensor somewhere around the cylinder head. Look around the top section of the timing belt/chain cover (in the front of the engine) or at the rear end of the cylinder head.
How to tell which cylinder is in power stroke?
To determine which cylinder is in its power stroke, your car's computer monitors the rotating position of the camshaft relative to the crankshaft position using a camshaft position (CMP) sensor. It uses this information to adjust the spark timing and the operation of the fuel injectors. Thus, the CMP sensor affects fuel economy, emissions control, and engine efficiency.
What does CMP mean in car?
A failing camshaft position sensor (CMP sensor) can produce a confusing range of problems, depending on the way it fails and the model of the car: On some vehicles, a failing camshaft sensor may lock the transmission in a single gear until you turn off and restart the engine. This cycle may repeat intermittently.
Why does my transmission lock in a single gear?
On some vehicles, a failing camshaft sensor may lock the transmission in a single gear until you turn off and restart the engine. This cycle may repeat intermittently.
Why does my CMP sensor stop working?
Just like every part or component in your car, the CMP sensor will eventually stop working when it's reached the end of its service life, because an internal part, wire, or related component has failed. The symptoms your engine may experience at this point can vary, depending on the type of sensor failure: for example, a problem in the circuit, the connector, the sensor itself, or a related component.
What type of camshaft sensor is used to check voltage?
The two most common camshaft sensors you'll see are the magnetic and Hall-effect types. Both transmit a voltage signal to an electronic control module or to the car's computer. The magnetic type produces its own AC (alternate current) signal (a sine wave), and you can identify it by its two wires.
Why does my camshaft sensor fail?
Camshaft position sensors usually fail due to normal everyday wear and tear, and accidents.
What happens if your camshaft sensor is not working?
With the wrong information, your engine will not be able to run as efficiently as it should causing it to consume more fuel.
Why won't my car start?
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
What is a camshaft position sensor?
The camshaft position sensor monitors the camshaft speed and position. It sends the collected data to the engine control module. The ECM is then able to determine how much fuel is needed and the timing of the spark.
Can you drive with a bad sensor?
Although you can continue to drive with a bad sensor, we do not recommend that you do so. Continuing to drive the car can lead to additional failures in other areas of your car, which can end up causing you to have a higher service bill. Your car can also stall when the sensor is failing. This can be dangerous to you, your passengers, and everyone on the road.
What causes a camshaft sensor to misfir?
If the camshaft position sensor waveform output is abnormal (as viewed on an automotive scope ), that can cause misfiring but such must first be confirmed by actually testing the sensor especially as there are many, many causes of misfiring and, in the absence of an actual diagnostic, no one of these causes is any more likely than the other to be the actual cause of your misfiring. Diagnostic Trouble Code P0300 can set if you have faulty spark plugs, low compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injectors, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft sensor, faulty mass air flow sensor, faulty oxygen sensor, faulty throttle position sensor, faulty catalytic converter, and others. If you want the cause of the misfiring pinpointed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a misfiring diagnostic and the responding certified mechanic will get this diagnosed and resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.
What does it mean when your car lights go into fail safe mode?

What is misfire detection?
The misfire detection is enabled after certain base information is received by the PCM. Typically, engine coolant temperature, cylinder head temperature, intake air temperature and, if equipped, the mass air flow sensor (or a combination of these) are used to evaluate the condition as well as the crank and cam positions.
Why does my check engine light come on?
Almost every emission problem that causes hydrocarbons to exceed 1.5 times the federal limit will cause the check engine light to come on even if there are no symptoms noticed by the driver. On some vehicles, the PCM will disable a particular cylinder’s fuel injector if the misfire is bad enough to cause raw fuel to be sent to the catalytic converter. This is generally determined by the comparison of the up and down stream O2 sensor information sent to the PCM. When the converter’s efficiency drops below a predetermined value, the service light will turn on.
What is the crank sensor?
With most engines, the crank sensor is the key component in determining a misfire. The PCM calculates the time between the edges of the crank reluctor wheel teeth by receiving a signal from the CKP sensor. The crankshaft rotational velocity and acceleration are compared in the event of a power loss from each cylinder. Advertisement.
Can vibration damage alternators?
High underhood temps, increased power demands and vibration can damage alternators or starters. Sponsored by ACDelco.
