Product Details

Standard Ignition SC725 is engineered for vehicles that use an output shaft speed sensor to report transmission shaft speed to the control system. On Fiat 500 and Fiat 500L applications, this sensor helps maintain accurate transmission input data so the vehicle can manage shifting and related drivetrain functions correctly. The bolt-mount layout, single connector, and terminal configuration support a straightforward replacement of the original sensor.

This part cross-references 68137842AA and SN8427 for the same application. When searching for a Fiat 500 transmission speed sensor or a Fiat 500L output shaft speed sensor, SC725 is the direct-fit reference to verify against your original part.

What It Helps Address

• Transmission speed signal loss or erratic output shaft readings
• Illuminated transmission or powertrain warning lights tied to sensor faults
• Harsh, delayed, or inconsistent shifting caused by incorrect speed data
• Drivability concerns related to transmission control input errors
• Replacement of a damaged or electrically failed output shaft speed sensor

Installation Notes and Tips

Confirm connector shape, terminal style, and bolt-mount location against the original sensor before installation. Inspect the mating connector and wiring for corrosion, bent terminals, or heat damage, since those issues can affect signal quality. Verify the transmission area is clean before removing the old sensor to help prevent contamination during service.

Compatible With 2012-2019 Fiat 500 and 2014 Fiat 500L applications listed above. Use the vehicle year and original part number SC725 to confirm application match before ordering.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management service parts. SC725 is built to meet the fitment and connector requirements of the listed Fiat applications for direct replacement service.
