Key Features

• Engine crankshaft position sensor for ignition and engine speed signal input
• Black housing with oval connector shape
• 3-terminal male pin connector with 1 connector and 1 mounting hole
• No wiring harness included and no mounting bracket included
• Package contents include the engine crankshaft position sensor and instruction sheet
• OE-calibrated and validated to support accurate readings

Detailed Description

Delphi SS12461 is engineered as a direct-fit crankshaft position sensor for vehicles that depend on consistent crankshaft timing information for engine control. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate signal output and reducing repeat repairs. This part cross-references Standard Ignition PC1242 for the same application. It is a practical replacement choice for drivers searching for a crankshaft position sensor for 2019-2020 Chevrolet Silverado 1500, 2019-2020 GMC Sierra 1500, or 2020 Cadillac CT4 and CT5 applications.

What It Helps Resolve

• Crankshaft signal loss or intermittent engine speed data
• Hard starting or extended crank conditions
• Engine stalling related to crank position input faults
• Misfire or timing-related drivability concerns
• Check engine light triggered by crankshaft sensor faults

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. The Delphi SS12461 uses a male oval connector with 3 terminals and 1 mounting hole, so matching the original sensor configuration is important for proper fitment. Inspect the connector and wiring for corrosion or damage before connecting the new sensor. Compatible With 2019-2020 Cadillac XT4, 2020 Cadillac CT4, 2020 Cadillac CT5, 2020 Chevrolet Silverado 1500, and 2019-2020 GMC Sierra 1500, among other listed applications.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for accurate readings. The SS12461 is part of Delphi’s sensor portfolio for engine management applications, including crankshaft, camshaft, MAP, throttle position, and vehicle speed sensing.
