Standard Ignition SC507 Automatic Transmission Input Shaft Speed Sensor

Automatic Transmission Input Shaft Speed Sensor

Standard Ignition SC507 is an automatic transmission input shaft speed sensor built for accurate signal output and reliable transmission monitoring. It uses OE-exact connectors and terminals for a proper fit on the transmission, making it a direct replacement for select Ford Fiesta and Ford Focus applications.

With precise signal amplitude and polarity control, this sensor supports consistent readings that help the powertrain control system manage shifting and engine operation. It is a practical choice for Ford Focus and Ford Fiesta owners looking for a transmission speed sensor replacement that matches OE-style connection and mounting details.

Key Features

• OE-exact connectors and terminals for proper electrical fit
• OE-style output signal for accurate transmission speed readings
• Female plug-in connector with square shape
• Bolt-mount design for installation on the transmission
• 2 blade terminals with male terminal ends
• Environmental, endurance, and end-of-line testing for signal amplitude and polarity
• Supports precise engine performance and emissions regulation

Detailed Description

The Standard Ignition SC507 transmission input shaft speed sensor is engineered to deliver the signal accuracy needed for modern automatic transmission control. Its OE-exact connector and terminal design helps ensure a secure electrical connection, while the bolt-mount configuration supports a direct replacement installation on the transmission housing. This part number, SC507, is built for consistent signal quality so the control module can monitor input shaft speed with confidence.

Fits 2017-2019 Ford Fiesta, Automatic Transmission Input Sensor. Fits 2018 Ford Focus, Automatic Transmission Input Sensor. Fits 2012-2017 Ford Focus, Gray. Fits 2010-2016 Ford Fiesta, Gray. This part cross-references Holstein (e.g., 2VSS0168) for the same application.

What It Helps Solve

• Erratic or inaccurate transmission speed sensor readings
• Harsh, delayed, or inconsistent shifting behavior
• Transmission warning lights related to input shaft speed data
• Poor engine control feedback from the transmission system
• Signal loss caused by worn connector or terminal interfaces

Installation Notes and Tips

Verify connector shape, terminal style, and mounting location before installation. This sensor mounts on the transmission with a bolt-mount design and uses a square, plug-in female connector with two blade terminals. Confirm the vehicle application by year, make, and model before replacing the original unit. For Ford Fiesta and Ford Focus service work, inspect the harness connector for corrosion or damaged terminals before connecting the new sensor.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing to verify signal amplitude and polarity. That testing helps support consistent performance and dependable transmission speed feedback across the listed Ford Fiesta and Ford Focus applications.
