Automatic Transmission Output Shaft Speed Sensor

Standard Ignition SC346 is a new automatic transmission output shaft speed sensor with a direct mount design and a single rectangular female connector. It is built for transmission-mounted applications on select Audi, Porsche, and Volkswagen vehicles, including Audi A4 Quattro, A6, A8, and Volkswagen Passat models.

Key Features

• Direct attachment and direct mounting for a straightforward replacement
• Black finish with a rectangular, plug-in connector
• Female connector with 2 blade terminals
• New sensor construction for transmission speed signal service
• No harness, bracket, dust shield, or mounting hardware included
• Standard Ignition SC346 cross-references Delphi SS11800 and Hella 009161001 for the same application

Detailed Description

Standard Ignition SC346 is an automatic transmission output shaft speed sensor used to monitor transmission output speed and send that signal to the vehicle control system. On many Audi A4 Quattro, Audi A6 Quattro, and Volkswagen Passat applications, the sensor is located on the transmission, making accurate fitment and connector style important during replacement. This part number, SC346, is also listed across multiple interchange references for select European vehicle applications.

What It Helps Address

• Transmission speed signal loss or erratic output shaft readings
• Speedometer operation issues tied to transmission sensor input
• Fault codes related to output shaft speed sensing
• Harsh or inconsistent shifting caused by incorrect transmission speed data
• Intermittent drivability concerns on transmission-mounted sensor systems

Installation Notes and Tips

• Verify the connector style, terminal count, and direct-mount layout before installation.
• Confirm the sensor location on the transmission, especially on Audi A4 Quattro and Volkswagen Passat applications.
• Inspect the mating connector and wiring for corrosion or damage before plugging in the new sensor.
• Use the vehicle fitment notes to confirm the exact year, model, and transmission application.

Quality Assurance

Standard Ignition supplies this as a new replacement sensor built to match the listed OE-style application details, including connector type, terminal configuration, and mounting style for the specified vehicles.
