Walker 235-91634 crankshaft position sensor for the 1993-1995 Porsche 928 V8 5.4L and other vehicles reports crankshaft speed and position to the engine control module. Also called a crank sensor, it supplies the data the module uses for ignition timing and fuel injection timing.
- Withstands temperature fluctuations, mechanical vibration, engine fluids and electromagnetic interference
- Can identify irregularities in engine cycles, which aids misfire detection
- Works alongside the camshaft position sensor to coordinate valve and piston movement
- Accurate position data lets the engine control module fine-tune fuel injection timing
- Full service kit: the sensor plus parts for a watertight wiring connection
Quick facts
- Part: Walker 235-91634 crankshaft position sensor
- Also called: crank sensor
- Fits: 1993-1995 Porsche 928 V8 5.4L and other vehicles
- Condition: New
A worn sensor can bring a no-start, stalling or a check engine light. Those signs alone do not prove the sensor is at fault, since a damaged wiring connector is another common cause.
Fits
It fits the 1989-1991 Porsche 928 V8 5.0L, the 1993-1995 928 V8 5.4L, the 1992-1995 Porsche 968 4-cylinder 3.0L and the 1983-1984 Porsche 944 4-cylinder 2.5L. Each car takes a single sensor, which is what this listing holds.

Frequently Asked Questions
Is this the crankshaft position sensor for the 1983-1984 Porsche 944 4-cylinder 2.5L?
Yes. Walker 235-91634 fits the 1983-1984 Porsche 944 4-cylinder 2.5L, and that car takes one sensor.
Does the Walker full service kit include a connector and splices?
Yes. Walker 235-91634 adds a mating connector, pigtail, butt splices and heatshrink to the sensor for a watertight connection.
How many terminals does this crankshaft position sensor have?
This sensor has three male blade terminals and one rectangular female connector.
Can a worn crankshaft position sensor cause a rough idle?
Yes. A worn sensor can bring on a rough idle, hard starting or misfires, since the engine control module times ignition and fuel injection from its signal.
Does Walker 235-91634 replace SU5998DG?
Yes. SU5998DG is listed as an interchange number for Walker 235-91634.
