Standard Ignition SC239 Automatic Transmission Output Shaft Speed Sensor

Automatic Transmission Output Shaft Speed Sensor

Standard Ignition SC239 is an automatic transmission output shaft speed sensor for select Honda applications. It provides the transmission speed signal used by the vehicle control system to monitor output shaft rotation and support proper shifting and drivability.

Key Features

• Automatic transmission output shaft speed sensor for Honda Accord and Honda Odyssey applications
• Bolt-mount design with one mounting hole for direct installation
• Black housing with a rectangular female socket connector
• 2 blade terminals, no wiring harness included
• Sensor-only construction for service replacement use
• Standard Ignition SC239 cross-references OE and aftermarket part numbers for the same application

Detailed Description

Standard Ignition SC239 is built as an automatic transmission output shaft speed sensor for 1998-2002 Honda Accord models with Toyodenso transmission applications and 1998 Honda Odyssey. This sensor helps the transmission control system read output shaft speed so the vehicle can manage shift timing and speed-related transmission functions. If you are searching for a Honda Accord transmission speed sensor or a Honda Odyssey output shaft speed sensor, SC239 is the direct-fit service part to compare against the original unit.

This part cross-references Honda OE 28810P6H003 and aftermarket references such as SN7172 for the same application. The SC239 part number is also useful when verifying replacement options for Honda Accord and Honda Odyssey transmission sensor service.

What It Helps Address

• Erratic or delayed transmission shifting
• Speed signal loss from the transmission output shaft
• Transmission warning lights related to sensor input
• Incorrect vehicle speed data reaching the control system
• Drivability concerns tied to output shaft speed feedback

Installation Notes and Tips

Confirm connector style, mounting location, and transmission application before installation. SC239 uses a bolt-mount design with a rectangular female connector and male blade terminals, so the replacement should match the original sensor interface. Inspect the connector, terminals, and surrounding transmission area for corrosion or damage before installing the new sensor.

Quality Assurance

Standard Ignition supplies replacement electrical and sensor components for service applications, and SC239 is built to match the listed Honda fitment and connector configuration.
