This part cross-references Bosch 96318 and Standard Ignition PC791 for the same application.

What It Helps Address

• Crankshaft position sensor fault codes
• Intermittent no-start or hard-start conditions
• Rough running caused by missing crank signal data
• Stalling related to crankshaft position signal loss
• Ignition timing and engine synchronization issues

Installation Notes and Tips

Verify connector shape, terminal count, and sensor body diameter before installation. Prenco 4D-1234 uses a rectangular female connector with 3 terminals and no mounting bracket, so the original mounting style should be confirmed against the vehicle. Always compare the existing sensor and connector to the part number 4D-1234 before replacement.
