Are there two crankshaft sensors on a Pontiac Montana transport van?

Yes, the Pontiac Montana, particularly in its later models, is equipped with two crankshaft position sensors. These sensors are typically located near the engine's crankshaft and are responsible for monitoring its position and rotational speed, which is crucial for proper engine timing and performance. If either sensor fails, it can lead to engine performance issues or starting problems. Always refer to the specific service manual for your model year for detailed information.
