This sensor tracks crankshaft rotation to identify piston position and engine speed, sending precise timing signals to the ignition and fuel systems. By doing so, it ensures smooth starts, efficient combustion, and consistent power delivery. It also supports key safety functions, including misfire detection and limp-mode protection.

A faulty crankshaft sensor can lead to hard starts, stalling, loss of power, or even engine shutdown. It may also trigger check-engine lights, misfires, and disrupt critical fuel and ignition timing. Replacing it ensures reliable performance, and helps prevent costly engine damage.

Common signs of a failing crankshaft sensor include hard starting or long cranking times, unexpected stalling, and rough idling or power loss while driving. You may also notice the check engine light triggered with related fault codes, misfires, or a drop in fuel efficiency.
