What is the code for Ford output shaft speed sensor?
There isn’t a single universal code for Ford output shaft speed sensors. The exact part number (code) depends on the vehicle’s year, model, and transmission family. This article guides you through identifying the right OSS sensor code for your Ford and where to source it.
Why there isn’t a single Ford OSS code
Ford uses different OSS sensors across multiple transmission families and generations. Because part numbers are tied to the specific transmission type and model year, you must know the exact transmission specification to obtain the correct sensor code. Using the wrong OSS part can lead to improper fit or electrical incompatibility.
How to identify the correct OSS code for your Ford
Before you start shopping for a replacement, organize the key details of your vehicle. The steps below help you pinpoint the right code by cross-checking the transmission family and VIN.
- Identify the transmission family and model year of your vehicle. Common Ford transmissions include 6R80, 6F35, 6F50, 4R70W, and others; each has its own OSS sensor.
- Locate the OSS on the transmission housing and inspect any labels or markings on the sensor itself, if accessible.
- Check the vehicle identification number (VIN) and use Ford’s official parts lookup or the dealership’s database to cross-check compatible OSS part numbers for your exact configuration.
- Consult the vehicle’s service manual or a certified Ford technician if you’re uncertain about which OSS fits your transmission.
- Confirm electrical connector style and mounting features (pins, clip style, and mounting bracket) to ensure a proper physical fit.
Correctly identifying the OSS code minimizes guessing and reduces the chance of ordering the wrong part. If in doubt, rely on the VIN-based lookup or contact a Ford dealer with your VIN for precise confirmation.
Where to source the correct OSS part number
Once you know your OSS code, use trusted sources to purchase or verify the part. The following avenues help ensure you get the right sensor for your Ford:
- Ford official parts website or the Ford Parts Catalog, which allows VIN-based searches to surface the exact OSS part number for your vehicle.
- Authorized Ford dealers or service centers, which can confirm compatibility using your VIN and service history.
- Reputable auto parts retailers that support VIN lookups and provide diagrams showing the sensor’s location and connector type.
- Shop manuals, workshop manuals, or ETIS (Ford’s electronic parts catalog) resources for detailed part diagrams and mounting specifications.
Relying on VIN-based searches and official catalogs helps ensure you order the correct OSS part for your specific Ford configuration and avoid mismatches.
Common diagnostic codes related to the output shaft speed sensor
Testing the OSS sometimes reveals diagnostic trouble codes (DTCs) that indicate sensor or circuit issues. While Ford-specific wiring and codes can vary by model, these are representative examples you might encounter with transmission speed sensor problems:
- P0720 — Output Speed Sensor Circuit Malfunction
- P0715 — Input/Turbine Speed Sensor Circuit Malfunction
- P0716 — Input Speed Sensor Circuit Range/Performance
- P0717 — Input Speed Sensor Circuit No Signal
Note that DTCs can differ by model year and software calibration. Always consult your owner’s manual, the Ford service information, or a dealership diagnostic tool for the exact interpretation on your vehicle.
Summary
In Ford vehicles, there is no single universal code for the output shaft speed sensor. The correct OSS part number is determined by your vehicle’s year, model, and transmission family, and must be verified via VIN-based parts lookup or the dealer. By identifying the correct transmission, consulting official catalogs, and matching connector and mounting features, you can ensure you order the right sensor and avoid compatibility issues. If you’re diagnosing a fault, be aware of common OSS-related codes, but rely on official sources to confirm the exact meaning for your specific Ford configuration.
