Engine Timing Sensor (Crankshaft Position) for Hyundai & Kia ⚙️

This sensor is a key input for the ECU to know exact crankshaft speed and position. It’s needed to fire the spark and inject fuel at the right moment, keep smooth idle, and protect the engine from mis-timing under load. Without a clean crank signal, modern Hyundai/Kia systems can’t calculate accurate ignition timing or cylinder synchronization.

How it works ?

The sensor reads a toothed wheel on the crankshaft. As the teeth pass the tip, it generates a precise pulse pattern. The ECU counts these pulses to determine RPM and identifies reference gaps to know crank angle. That data is used for start-up fueling, misfire detection, and stable acceleration.

Signs of a failed sensor & what can happen ?

Common symptoms

• Hard start or no start
• Stalling when hot, then restarts after cooling
• Rough idle, hesitation, weak acceleration
• Check Engine light + stored crank signal codes

If it breaks completely, the ECU may cut spark/injection for safety—leaving you stranded. Intermittent failure can cause random cut-outs and extra stress on the starter and battery.
