What does the cam sensor control?
The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.
How does a cam sensor work?
The Camshaft Position Sensor detects camshaft rotation, and is mounted near the cylinder head so that the sensor is opposite to the timing rotor attached to the engine camshaft. The engine ECU detects the camshaft angle, and performs cylinder recognition based on the signals detected by the camshaft position sensor.
What does a camshaft position sensor do in a car?
What Is a Camshaft Position Sensor and What Does It Do? A camshaft position sensor is an electronic device that does what it suggests — monitor the camshaft position and speed — and feeds that data to the vehicle’s engine control module (ECM).
What can cause a camshaft sensor to fail?
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. A camshaft position sensor (or any sensor) can fail due to wear-and-tear or an accident. Here’s what you need to know. What Is a Camshaft Position Sensor and What Does It Do?
How does the crankshaft and camshaft work together?
The camshaft and crankshaft are two of these important components. The camshaft controls the position of the inlet and exhaust valves, while the crankshaft controls the location of the pistons themselves. If a camshaft controls those valves, what is a camshaft position sensor, and why is it necessary?
How much does it cost to replace a camshaft sensor?
Camshaft Position Sensor Replacement Cost. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200. Labor costs will be in the range of $70 to $100 for professional replacement.
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.
What will a bad cam shaft sensor do?
A faulty camshaft position sensor will cause an improper amount of fuel to be injected into the cylinder chamber. The engine will not respond very well to this because it depends on a proper mixture of air and fuel to function adequately. When you step on the gas pedal to accelerate, you will notice weaker performance.
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 causes a cam sensor to go bad?
The camshaft position sensor can be damaged over time by an accident or regular wear and tear . Sometimes it is also damaged by oil leaks and cracks . The most common symptoms of a bad camshaft position sensor are hard starting condition, check engine light, misfires, and engine performance problems.
