Standard Ignition SC501 Automatic Transmission Input Shaft Speed Sensor

Automatic Transmission Input Shaft Speed Sensor

Standard Ignition SC501 is an automatic transmission input shaft speed sensor built for OE-style fit and signal accuracy. It uses OE-match connectors and terminals to help maintain proper electrical connection, while the output signal is engineered to deliver consistent readings for transmission control.

Compatible with select Ford, Lincoln, and Mercury applications, including Ford Explorer, Ford Edge, Ford Flex, Lincoln MKT, and Lincoln MKX models across multiple years.

Key Features

• OE-match connectors and terminals for proper fit
• OE-match output signal for accurate transmission speed readings
• Precision-manufactured components for consistent performance
• 100% environmental, endurance, and end-of-line tested
• Built to verify signal amplitude and polarity before release
• Standard Ignition SC501 replacement for transmission input speed sensor service

Detailed Description

The Standard Ignition SC501 automatic transmission input shaft speed sensor is engineered to provide the transmission control system with accurate input speed data. That information supports shift timing, drivability, and overall transmission operation. The connector design, terminal layout, and signal output are matched to OE requirements, making this sensor a direct-fit service part for many Ford Explorer, Ford Edge, Ford Taurus, Ford Flex, Lincoln MKT, Lincoln MKX, Lincoln MKS, Lincoln MKZ, and Mercury Sable applications. This part cross-references Dorman - OE Solutions 917-604 for the same application.

What It Helps Address

• Harsh, delayed, or inconsistent shifting caused by incorrect input speed data
• Transmission warning lights related to sensor signal faults
• Erratic transmission control module readings
• Drivability concerns tied to inaccurate shaft speed feedback
• Electrical connection issues from worn or mismatched sensor terminals

Installation Notes and Tips

• Verify the connector shape, terminal style, and vehicle application before installation.
• Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs.
• Clear diagnostic trouble codes after installation and confirm proper transmission operation.
• Use the vehicle service information for the exact sensor location and removal procedure.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing to confirm signal amplitude and polarity. That testing helps support consistent operation and reliable OE-style performance in service.
