Common Issues This Part May Address

• Hard starting or extended crank time
• Intermittent stalling or sudden engine shutdown
• Check engine light related to crankshaft position signal faults
• Rough running caused by an unstable engine speed signal
• No-start condition when the crank signal is lost

Installation Notes and Tips

Confirm connector shape, terminal count, and harness length against the original sensor before installation. Inspect the mating connector for corrosion, damaged terminals, or heat-related wear, and verify the mounting location is clean and free of debris. Because no mounting bracket is included, reuse the existing bracket or mounting arrangement if required by the vehicle.
