9091905070 Toyota SENSOR, CRANK POSITION, Price: 66.58$, Weight: 0.06kg

Crankshaft Position Sensor for Toyota Engines ⚙️

This OEM-grade engine timing sensor keeps your Toyota powerplant perfectly in sync. It tracks crank angle and rpm so the ECU fires spark and injects fuel with millisecond accuracy. Built with a precision magnet core, sealed connector, and high-temp housing, it’s a direct-fit replacement that restores reliable starting, smooth idle, and clean emissions.

Why this part is needed

Accurate crank feedback is the backbone of ignition and fueling. A healthy sensor delivers quick cold and hot starts, strong mid‑range pull, stable idle, and better fuel economy. Replacing a tired unit prevents random cutouts and protects the catalytic converter.

How it works

A toothed reluctor on the crankshaft passes the tip; changes in the magnetic field generate a waveform. The ECU counts teeth, spots the missing-tooth index for TDC, and synchronizes with the cam signal for sequential injection and knock control.

What happens if it fails ⚠️

Symptoms include no-start (often when hot), sudden stall, hesitation, misfire, rough idle, poor mileage, erratic tach, and a Check Engine light (codes like P0335/P0336). Long-term driving can overheat the catalyst due to unburned fuel.

Fitment and technician tips

Match connector keying and mounting tab. Inspect the tone ring for bent or dirty teeth. Set correct air gap, torque the hold-down, and route the harness away from exhaust heat. Clean metal filings from the tip, clear codes, and perform idle relearn after install. ✅
