Crankshaft Position Sensor Replacement
What is a crankshaft position sensor?
The crankshaft position sensor is located near the engine's crankshaft, and relays information about the crankshaft’s position as it rotates.
How does the crankshaft position sensor work?
As the crankshaft spins, the position sensor magnetically reads its position. This information is constantly sent to the engine's computer for comparison with data from the camshaft position sensor.
When the two signals reach the computer, they must match; otherwise, the computer will think there is a mechanical error in the engine and will adjust some settings in response.
Several symptoms may occur when a crankshaft position sensor is failing or has failed. These symptoms can include:
Check Engine Light will illuminate
Engine will crank over but not start
Engine may stall while driving
Poor engine performance (hesitating, misfiring, and lack of power)
