Detailed Description

Standard Ignition SC823 is an automatic transmission input shaft speed sensor used to monitor transmission input shaft speed for the vehicle control system. This sensor is listed for 2020-2025 Hyundai Palisade, 2020-2024 Kia Telluride, 2019-2021 Kia Sedona, 2019-2020 Hyundai Santa Fe, and 2019-2020 Kia Sorento, making it a direct-fit service part for several late-model Hyundai and Kia applications. The SC823 uses a bolt-on mounting method, a rectangular female connector, and 6 male blade terminals for a straightforward OE-style replacement.

This part cross-references Standard Ignition SC823 for the same application.

Common Replacement Reasons

• Transmission speed signal loss or erratic input shaft speed readings
• Check engine light related to transmission sensor performance
• Harsh, delayed, or inconsistent shifting caused by sensor faults
• Transmission control concerns tied to inaccurate input speed data
• Failed sensor diagnosis during transmission electrical testing

Installation Notes

Verify connector shape, terminal count, and bolt-mount style before installation. This sensor uses no wire harness, so the vehicle-side connector must match the rectangular female socket configuration. Confirm the application by year, make, and model before service, especially on Hyundai Palisade, Kia Telluride, and Kia Sorento vehicles.

Quality Assurance

Standard Ignition replacement sensors are built for service use in transmission and engine management applications. SC823 is a new part intended for direct replacement on the listed Hyundai and Kia vehicles.
