Ford F150 Codes List – What You Need to Know

Diagnostic trouble codes (DTCs) are error codes stored in a vehicle’s on-board computer to indicate a problem is detected. A diagnostic tool, such as an OBD-II scanner, can read these codes to help determine the cause of car trouble and guide you through fixing it.

Both car owners and repair shops can benefit from knowing how to read diagnostic trouble codes. When the error code is found, the source of the problem can be zeroed in on and fixed. Today, we’re going to focus on the types of error codes that show up on Ford F150s.
