What This Sensor Helps Address

  • Crankshaft position signal loss that can affect ignition timing
  • Hard starting caused by an inaccurate engine speed reference
  • Stalling or intermittent shutdown related to crank signal interruption
  • Misfire conditions tied to poor crankshaft sensor input
  • Check engine light concerns associated with crankshaft position sensor faults

Installation Notes and Tips

Verify the sensor location before installation, since listed applications place the sensor either at the timing cover or behind the balancer depending on vehicle and engine configuration. Confirm the connector style, terminal count, and harness routing against the original part before replacement. For Buick Regal applications, the fitment notes specify a 3-pin configuration.

Quality Assurance

Prenco 4D-1038 is an OE-style replacement sensor built to match the listed GM applications and interchange references. Use the vehicle fitment details and connector specifications to confirm proper application before installation.
