A camshaft sensor determines the exact position of your engine’s camshaft, helping your car keep your engine’s combustion running smoothly. Many modern engines have one camshaft sensor for each camshaft. This can mean up to four, although some cars will only have two.
What are the symptoms of a failed camshaft position sensor?
A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. Gone are the days of carburetors and distributors, replaced by a variety of sensors that help a car’s computer get the maximum performance out of the engine.
Where is my camshaft position sensor located?
The Camshaft Position sensor is typically located in the cylinder head of the engine and has a cylindrical portion that inserts into the head. The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.

What do you do after replacing camshaft sensor?
After changing the sensor remember to cancel the error codes stored in the engine controller after the failure by means of a diagnostic scanner. If fitted properly, a new sensor should restore correct operation of the engine. The sensor itself is not repairable and cannot be reused in the event of a failure.
Is a camshaft sensor serious?
Driving with a Bad Camshaft Position Sensor 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.
How do you manually relearn a crankshaft position sensor?
Can you drive without crankshaft relearn?
Engine won’t start Without relearning, the ECU sometimes doesn’t get the accurate location of the crankshaft and engine speed. The ignition will not maintain the correct timing of spark plug fires, which can affect the vehicle’s regular operation. The engine will not be able to start because of this obstacle.
How much does it cost to relearn crankshaft position sensor?
