Ford trouble codes, also known as OBD-2 trouble codes, play a central role in diagnosing and troubleshooting technical problems in Ford vehicles. These codes are used to identify specific anomalies in the operation of the vehicle and provide technicians and mechanics with a basic guideline for effective failure analysis.
Among Ford models, certain models are particularly prone to error codes. These include models such as the Ford Focus, Ford Fiesta and Ford Fusion. These vehicles, which are widely used, show an increased propensity for error codes due to their variety of electronic components and advanced systems.
For example, a common error code that can occur on these models is P0420, which can indicate problems with the catalytic converter. Another common code is P0171, which can indicate a lean fuel-to-air ratio in one of the cylinders.
To access Ford trouble codes, a diagnostic device such as an OBD-II scanner is used. This device makes it possible to read and interpret the error codes from the vehicle’s on-board diagnostic system. A thorough understanding of these codes is critical to making accurate diagnoses and making necessary repairs.
The first character is a letter that determines the type of defective system:
- P – malfunction of the power unit or transmission (automatic transmission).
- B – malfunctions in the operation of body systems – airbags, electric windows, central locking, etc.;
- C – malfunctions in the chassis of the vehicle;
- U – errors associated with the interaction of electronic modules.
The second character is a number that determines the specificity of the malfunction:
- 0 – general symbol for OBD block;
- 1 and 2 – personal codes of the car manufacturer;
- 3 – reserved information.
The third character determines the type of failure:
- 1 and 2 – air or fuel supply;
- 3 – ignition unit, system for detecting misfires of the air-fuel mixture;
- 4 – additional emission control mechanism;
- 5 – control of vehicle speed and idle speed;
- 6 – electronic control modules, as well as their wiring;
- 7, 8 – errors in the operation of the gearbox;
- 9, 0 – reserve.
The fourth and fifth digits of the error are a number that corresponds to the serial number of the malfunction.

Table with OBD2 errors
| Error code |
Common errors |
|---|---|
| P0000 | Code P0000 means that no errors were detected in the control unit memory |
| P1000 | The EOBD system has not been tested before use. Code P1000 does not indicate a malfunction, but indicates self-tuning of the EOBD. Combination 1000 appears after calibration of the control unit, which led to the memory being reset. The code should be removed automatically |
| Error code |
Fuel system errors |
| P0001 | Malfunction of the fuel supply control system. Error 0001 may be due to a sensor failure or a power line break. Possible short circuit or oxidation of contacts |

How to diagnose the error?
The first sign of a malfunction in Ford vehicles is the appearance of a “Check Engine” or “APC” indicator on the dashboard. These inscriptions indicate problems in the operation of the vehicle systems, therefore, to obtain accurate information about the breakdown, diagnostics should be carried out.
To carry out self-diagnosis, perform the following steps:
- The driver inserts the key into the lock and activates the ignition system. There is no need to start the power unit.
- The daily mileage reset button is pressed on the dashboard; it is located on the odometer. The key must be pressed.
- At the same time, the key in the lock is rotated to position II.
- The “Test” indicator will appear on the control combination screen, then the button will be released. Errors will begin to be displayed that must be decrypted.
Ford self-diagnosis is a less accurate testing option; to obtain complete information about errors, it is better to use a computer with a program or a scanner.
Computer diagnostic process:
- The OBD output is prepared in the car for testing. Depending on the Ford model, the block may be installed under the steering wheel, car radio, behind the glove box or under the hood. On some versions the connector is located in the luggage compartment.
- An adapter is connected to the diagnostic output. Its second part is connected to the USB port of the computer.
- The ignition is activated, but the power unit does not start.
- A diagnostic utility is launched on the computer or laptop. The verification process begins. After testing, a list of errors that need to be deciphered will be displayed on the computer display.
How to reset the error?
There are several options that allow you to “treat” Ford errors:
- Using an ELM 327 scanner or another equivalent. Using the device, you can directly delete combinations of faults from the control unit memory.
- Battery disconnection. You need to disconnect the negative terminal from the device for a few minutes, then connect it back. But this option does not always help resolve the problem.
- Use of a computer with appropriate software. If the utility allows you to read errors, then it should have a function for deleting information.
