Dorman Engine Crankshaft Position Sensor 917-754 — Direct-Fit Replacement, Heat-Resistant

The Dorman 917-754 Engine Crankshaft Position Sensor is a direct-fit replacement sensor engineered to restore accurate crankshaft position signals to your vehicle's engine control unit.

If the original crankshaft position sensor in your vehicle has failed due to heat, vibration, or internal component wear, the engine control unit (ECU) can lose the timing input it needs to manage ignition and fuel delivery. The Dorman 917-754 is built to match OEM fit and function so you can replace a faulty unit quickly with confidence. It is manufactured to controlled specifications and supported by Dorman's long-standing automotive expertise.

How does this sensor restore engine timing accuracy?

The crankshaft position sensor monitors the crankshaft's rotational position and speed, sending a signal to the ECU so ignition timing and fuel injection are synchronized with piston movement. Replacing a failed sensor with a component that matches the original ensures the ECU receives clean, consistent pulses for reliable engine operation.

• Direct replacement designed to match original fit and function
• Provides consistent signal output for ECU timing calculations
• Helps prevent misfires and erratic idle caused by intermittent inputs

What makes the Dorman 917-754 durable and reliable?

Dorman engineers this sensor to withstand the heat and vibration typical in engine bays. Quality control and materials selection focus on long-term stability of internal components so the unit maintains signal integrity under stress.

• Manufactured to controlled specifications for consistent performance
• Constructed to resist thermal cycling and mechanical vibration
• Supported by Dorman’s product experts and automotive experience

How do I confirm fitment for my vehicle?

Before purchasing, use the vehicle lookup tool on the product page to confirm compatibility. Look for the Confirmed Fit indicator and check any fit notes marked with an informational icon to verify match details for your year, make, and model.

• Enter vehicle details into the garage tool on the product page
• Check the Confirmed Fit bar for a clear match indication
• Hover over the blue “i” icon to review any additional fitment notes

What should I expect when installing the replacement sensor?

Installation typically involves unplugging the electrical connector, unfastening the sensor, removing the old unit, and installing the new sensor in its mounting location. Basic hand tools are often sufficient, but follow vehicle-specific service guidance for torque specs and alignment procedures.

• Unplug electrical connector and remove mounting fastener(s)
• Seat new sensor to the same depth and orientation as the original
• Reconnect wiring and verify ECU recognizes the sensor after start-up

Who this is for: The Dorman 917-754 is aimed at do-it-yourself mechanics, independent repair shops, and fleet technicians who need a dependable, direct-replacement crankshaft position sensor that restores accurate engine timing signals. If your vehicle exhibits symptoms like check engine lights related to crankshaft/engine speed, rough idle, or stall conditions and the diagnosis points to a failed sensor, this unit provides a straightforward swap to get the engine control system receiving proper inputs again. Always confirm fit with the vehicle lookup tool and follow manufacturer service instructions during installation.
