Detailed Description

Delphi SS12438 is an engine crankshaft position sensor engineered to provide precise crankshaft position feedback to the engine control system. Delphi validates its sensors through OE-focused development methods and calibrates them to OE standards, helping maintain accurate signal output and consistent engine operation. This part cross-references Standard Ignition PC1257 for the same application. It is a direct-fit style replacement for select Hyundai and Kia models, including Hyundai Sonata, Santa Fe, Tucson, and Santa Cruz, plus Kia K5, Sorento, and Sportage. The SS12438 part number is useful when verifying the correct sensor for these applications.

What It Helps Address

• Crankshaft position signal loss or erratic signal output
• Engine stalling or hard starting related to crank sensor failure
• Misfire or rough-running conditions caused by incorrect timing input
• Check engine light concerns tied to crankshaft position sensor faults
• Intermittent drivability issues on Hyundai and Kia engine management systems

Installation Notes and Tips

Confirm connector shape, terminal count, and harness length before installation. The Delphi SS12438 uses a rectangular male connector, 3 terminals, and a 318 wiring harness length with one mounting hole. Verify vehicle application by year and model before ordering, especially on Hyundai Sonata 2020-2023, Santa Fe 2021-2023, Tucson 2022-2023, Santa Cruz 2022-2023, and Kia K5 2022-2023, Sorento 2021-2023, and Sportage 2023. The part number SS12438 should be matched to the original sensor configuration during service.

Quality Assurance

Delphi backs this sensor with OE development and validation methods, and each unit is tested and calibrated to OE standards to support accurate readings and reduce comebacks. The SS12438 is built as a quality replacement for select Hyundai and Kia crankshaft position sensor applications.
