The Crankshaft Signal Disk 2.4 is a critical engine management component designed for precise 2.4-liter engine applications. Mounted directly onto the crankshaft, this disk, often called a reluctor wheel, features a specific pattern of teeth or notches. As the crankshaft rotates, this pattern passes by a crankshaft position sensor, generating a fluctuating magnetic field that is converted into a digital voltage signal. This signal is the primary data source for the engine control unit (ECU) to determine the exact position and rotational speed of the crankshaft.

Accurate data from the Crankshaft Signal Disk 2.4 is fundamental for optimal engine performance. The ECU uses this real-time information to calculate and command precise fuel injection timing and ignition spark events. This ensures efficient combustion, maximizes power output, and contributes to reduced emissions. Any damage, such as a missing tooth or warping, or improper alignment of the signal disk can lead to incorrect timing. Symptoms of a faulty disk include hard starting, rough idling, engine misfires, a noticeable loss of power, and the illumination of the check engine light.

Manufactured from high-grade materials to withstand extreme engine temperatures and constant rotational forces, this OEM-specification Crankshaft Signal Disk 2.4 guarantees perfect compatibility and reliable operation. When replacing a faulty crankshaft position sensor, it is prudent to inspect the signal disk for integrity. Installing a new, precision-engineered disk restores the essential timing data stream, ensuring your 2.4-liter engine runs smoothly, efficiently, and reliably for the long term.
