Product Details

Cardone’s Engine Crankshaft Position Sensor line focuses on remanufactured ignition components that are tested for dependable operation before release. Part number 31-S4403 is engineered for vehicles that need accurate crank angle signal input to support ignition timing and engine start-up performance. This part cross-references Mitsubishi OE numbers MD121786 and MD152651 for the same application.

Compatible With 1990 Mitsubishi Eclipse, N/A; 1989-1990 Mitsubishi Galant, N/A; and 1990 Plymouth Laser, N/A. Use 31-S4403 when replacing a failed crankshaft position sensor on these vehicles, including Mitsubishi Eclipse and Mitsubishi Galant models that rely on stable sensor output for proper engine control.

Common Problems This Part Can Address

• Hard starting or no-start conditions caused by a weak crank signal
• Intermittent stalling related to inconsistent ignition timing input
• Check engine light concerns tied to crankshaft position sensor faults
• Poor engine performance from inaccurate pick-up signal delivery
• Oil leakage or premature sensor failure from worn OE-style components

Installation Notes and Quality Assurance

Verify connector style, mounting location, and vehicle application before installation. Clean the mounting surface and inspect the harness for damage or corrosion so the replacement sensor can deliver a stable signal. Follow the included instruction sheet and confirm proper routing of the wire harness during installation.

Each unit is computer tested and remanufactured to meet or exceed OEM performance standards. Cardone’s process also replaces or repairs OE components with high failure rates to improve reliability in service. This part is an e-waste item and should be handled according to local recycling requirements.
