Crankshaft Position Sensor For 95-10 Ford/01-04 Mazda/95-97 Mercury-6740816

Crankshaft Position Sensor for Ford, Mazda, and Mercury

This crankshaft position sensor monitors crankshaft rotation and sends the signal the engine computer needs to time ignition and fuel delivery, replacing OEM cross-reference 6740816.

Overview

This crankshaft position sensor is the component that tells the engine control module where the crankshaft is and how fast it is turning. A healthy crankshaft position sensor keeps ignition timing and fuel injection synchronized so the engine starts reliably and runs smoothly. It suits owners of older Ford, Mazda, and Mercury vehicles chasing a no-start or rough-running fault.

Built For Performance

• Direct-fit replacement matching the OEM footprint and connector style
• Sealed sensor body shields the internal element from oil and road grime
• Rugged housing resists heat cycling in the engine bay
• Plug-and-play wiring connection for a straightforward swap
• Built to deliver a consistent signal across the operating range

Fits These Machines

• for Ford vehicles from 1995 through 2010
• for Mazda vehicles from 2001 through 2004
• for Mercury vehicles from 1995 through 1997

On-The-Job Use

• Restoring ignition timing on engines that crank but will not fire
• Curing rough idle and misfire symptoms traced to a weak crank signal
• Routine replacement during timing or engine bay service
• Diagnostic repairs after a crankshaft position sensor fault code

Good To Know

Q: What are the signs of a failing crankshaft position sensor? A: Common symptoms include hard starting, stalling, misfires, and a check engine light with a crank sensor code. Replacing a failed crankshaft position sensor often restores normal starting and running.

Q: Does this sensor need programming after installation? A: No programming is typically required for this type of crankshaft position sensor, but the fault memory should be cleared after fitting. Confirm the connector matches your original before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
