Application Details

Compatible With 1997-2005 Buick Century, 2000-2005 Chevrolet Impala, 1997-2005 Chevrolet Monte Carlo, 1997-2003 Pontiac Grand Prix, 1997-2001 Chevrolet Lumina, 1997-1998 Buick Skylark, 1997-1998 Pontiac Grand Am, and 1997 Oldsmobile Cutlass Supreme. In these applications, the sensor is located in the timing cover. Delphi SS12123 is a direct-fit crankshaft position sensor choice for drivers searching for a 1997-2005 Buick Century crankshaft position sensor, a Chevrolet Impala timing cover crank sensor, or a Pontiac Grand Prix engine speed sensor replacement.

This part cross-references Standard Ignition PC82 and Walker Products 235-1131 for the same application.

What It Helps Address

  • Crankshaft signal loss that can trigger a no-start condition
  • Intermittent stalling related to inaccurate engine speed input
  • Rough running caused by inconsistent ignition timing data
  • Check engine light concerns tied to crank sensor faults
  • Hard starting after heat soak or sensor degradation

Installation Notes

Verify the connector shape, terminal count, and timing cover mounting location before installation. Clean the mounting surface and inspect the harness routing to help ensure a secure electrical connection. Use the included instruction sheet during replacement and confirm proper sensor seating after installation.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplier knowledge used by major automakers. That OE heritage is reflected in the design and engineering approach behind SS12123.
