Vehicle Speed Sensor for Acura Applications

Standard Ignition SC770 is a vehicle speed sensor built for transmission-mounted applications that require a 3-terminal electrical connection and bolt-mount installation. It is a direct-fit replacement for select Acura RLX and Acura MDX models, including vehicles with the plastic sensor application noted in fitment.

Key Features

• Vehicle speed sensor for transmission mounting
• Bolt-mount design for secure installation on the transmission
• Female connector with male terminals
• 3-terminal configuration
• Direct replacement for select Acura RLX and Acura MDX applications

Detailed Description

Standard Ignition SC770 is engineered as a transmission-mounted vehicle speed sensor for accurate speed signal input in supported Acura drivetrains. The female connector and 3-terminal layout help match the original electrical interface, while the bolt-mount design supports a stable fit at the transmission location. This part number, SC770, is listed for 2014-2017 Acura RLX with the plastic sensor application and 2017-2019 Acura MDX, as well as 2018-2020 Acura RLX.

This part cross-references OE-style numbers such as 28810R9T003 and SN8472 for the same application. If you are replacing a failing Acura RLX or Acura MDX vehicle speed sensor, SC770 provides a direct-fit option that aligns with the original mounting and connector style.

Common Issues This Part Can Help Resolve

• Inaccurate vehicle speed readings
• Transmission-related speed signal faults
• Intermittent speedometer operation
• Diagnostic trouble codes related to vehicle speed input
• Harsh or inconsistent shifting caused by speed signal loss

Installation Notes and Tips

Install SC770 on the transmission at the original sensor location and confirm the connector orientation before securing the bolt mount. Inspect the harness connector, terminals, and surrounding transmission area for corrosion, damage, or fluid contamination before installation. Verify the replacement matches the vehicle’s original sensor style, especially on 2014-2017 Acura RLX models noted with the plastic sensor application.
