Where is the camshaft position sensor A in a 2000 Chevy Malibu 3.1L V6 there 3 sensors on this car which one A?

There isn't a universally standardized naming convention "Sensor A," "Sensor B," etc., for camshaft position sensors across all vehicles, including the 2000 Chevy Malibu 3.1L V6. The location and naming will depend on the specific repair manual or parts diagram for that exact year and engine.

The 2000 Chevy Malibu 3.1L V6 likely has:

* A Crankshaft Position Sensor (CKP): This is crucial for engine timing.

* Two Camshaft Position Sensors (CMP): One for each cylinder head (bank) of the V6.

To find the sensor(s) you need:

1. Consult a Repair Manual: A Haynes or Chilton repair manual specific to your 2000 Chevy Malibu 3.1L V6 will have diagrams showing the location of all sensors. This is the most reliable method.

2. Use a Parts Diagram: Online auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to look up parts diagrams for your specific vehicle. These diagrams often show sensor locations.

3. Look at the Engine: The CMP sensors are usually located on the cylinder head, near the camshaft. They're typically small and have a single wire harness connector. However, without a diagram, identifying which is "A" is impossible.

In short: You *must* use a repair manual or parts diagram to identify the correct camshaft position sensor(s) on your car. Relying on general descriptions is unreliable and could lead to incorrect identification and further damage.
