Engine Crank Sensor, OE-Grade Replacement ⚙️
This critical pickup feeds the ECU a precise crank angle and speed signal so your engine fires at the right time, every time. It ensures clean starts, smooth idle, strong mid‑range, and low emissions. Ideal for restoring factory performance on daily drivers and fleet vehicles ?.
Why this part is needed
Modern ignition and injection depend on exact crank timing. The unit tells the ECU where top dead center is and how fast the crank spins, enabling correct spark advance and fuel delivery.
How it works
A magnetic core and Hall/inductive element read a toothed wheel on the crank. As teeth pass, it creates a waveform the ECU converts into RPM and position. It syncs with the cam sensor for sequential injection and knock control.
What happens if it’s damaged ⚠️
Hard or no start, long cranking, random misfire, stalling when hot, poor fuel economy, erratic tach, and fault codes like P0335–P0339. Prolonged failure can foul plugs and harm the catalytic converter.
Build, fitment, and quality ✅
OE-grade connector, heat‑resistant housing, sealed electronics, and exact mounting geometry for a tight air gap. Bench‑tested for signal strength, vibration, and thermal cycling.
Pro install tips ?
Disconnect battery. Clean the bore, lightly oil the O‑ring, and torque to spec. Route the harness away from the exhaust. Inspect the reluctor for damage. Perform CKP relearn with a scan tool for stable idle and quick starts.
