Ford Focus 2 error codes in Russian

Every complex mechanism, and especially such as a modern car, consists of many systems, components and assemblies. Most of them are constantly under load and the influence of various forces that can gradually destroy the materials from which the parts are made. Not a single high-quality mechanism lasts forever and is not guaranteed against periodic breakdowns. It is very convenient if such a breakdown can be quickly found and repaired.

Ford Focus 2 is equipped with a modern on-board computer, which, based on a set of symptoms, is able to determine the presence of breakdowns and recognize their causes. The computer informs the driver about detected problems using special short codes, each of which indicates a specific malfunction or error in the operation of a particular vehicle system. Therefore, it is extremely important to know what these codes mean in order to respond in time and fix the problem.

Determine the breakdown

Correctly deciphering the codes is the key to quickly identifying the cause of the problem and eliminating it. If an error code appears on your computer screen, you can contact a specialized automotive service center, where professional technicians, using specialized equipment, will carry out the necessary procedures to diagnose your Ford Focus 2. Comprehensive diagnostics will help identify the real causes of the problem. The fact is that it cannot be ruled out that problems with electronics may also provoke computer errors.

This procedure, however, is very expensive. There are several recommendations that will help you save money by diagnosing yourself. It is also worth noting that self-diagnosis is not as accurate as professional diagnostics.

So, to identify the causes of 2 problems found in your Ford Focus:

Turn on the car ignition, but do not start the engine.
Press and hold the button that resets the daily mileage on the car’s dashboard.
Hold the button down for several seconds.
Move the key to the next position without pressing the reset button.
Wait until the word “Test” appears on the odometer display.
Release the button. Pressing the key for more than 3 seconds between tests will reset the self-test process. In order to return to it, you need to start the car. During startup, the starter will automatically turn off and after a couple of seconds the computer will resume self-diagnosis.

To interrupt the self-diagnosis of the Ford Focus 2, you need to turn off the ignition and press the reset button on the odometer display for more than 3 seconds.

As a result of self-diagnosis, the on-board computer will issue cipher codes, according to which you can determine how the computer recognizes any breakdowns or malfunctions in the vehicle. Experts say you shouldn't expect highly accurate results. Thus, if the owner of a Ford Focus 2 is concerned that significant problems have occurred with the car, it is still worth seeking the help of professionals who can correctly read error information using special equipment.

How to diagnose a car?

You can check the automotive systems of vehicles used on Russian roads, regardless of the type of fuel (gasoline or diesel), using several methods:

using the odometer button;
using the OBDII diagnostic electronic connector;
using a jumper.

The described methods for checking “European” and “American” Ford 2000, 2006 and other model years are suitable for the following models:

Fusion;
Transit;
FF3 (Ford Focus 3) restyling and pre-restyling;
Kuga 2005, 2007, 2008 and other years of production;
Ranger;
Cargo;
Fiesta 2011, 2013;
Escape, etc.

Using the “Reset daily mileage” button

Diagnosis of problems in the operation of diesel and gasoline engines of the Ford Ranger, Kuga 1.6 liter and other models using the odometer button is done as follows:

The user inserts the key into the ignition switch and turns it to position “1”; there is no need to start the engine.
On the instrument panel of the S Max, Transit or Fusion, press the reset button for daily mileage; it is located under the display. The control element must be pressed and held in this state for several seconds.
By holding the button, the car owner turns the key to position “2”.
A message will appear on the instrument panel screen indicating that the menu test has begun, after which the key can be released. The letter symbols on the dashboard of Ford Focus, Mondeo and other models must be deciphered. Breakdowns and their causes are eliminated.
To automatically turn off the diagnostic mode, you need to hold down the daily mileage button for three seconds. To perform this task, you can also turn off the ignition, then turn it on and start the engine.

The “A Couple of Useful Things” channel talked about self-diagnosis of Ford cars using the daily mileage reset button.

Using a PC or scanner

Diagnostics of Ford Fusion cars and other models using a computer and OBD connector is the most accurate way to obtain information about faults.

To check, perform the following steps:

The tester is connected to a computer or laptop; its second contact must be connected to the diagnostic socket. In Ford cars, the outlet is usually installed to the left of the steering wheel and can be hidden by plastic decorative trim.
The key is turned in the lock to turn on the ignition. In some car models it is not necessary to activate it; this point should be clarified in the service book.
A utility for diagnosing faulty systems is activated on the laptop. Typically, programs allow you to select the type of node to be scanned. The user can separately test a manual transmission or automatic transmission (manual and automatic transmission, respectively), sensors or electrical circuits.
The car check begins; the procedure may take some time. After testing, the display will display information about any problems present in the vehicle. The combinations are deciphered so that the user can repair faulty components.

By jumper

To check the operation of systems using a jumper, a piece of wire must be equipped with an LED:

The connection of contact elements to the pins of the block is carried out taking into account the diagram. The negative output is connected to the third socket, and the positive output is connected to the positive terminal of the car battery.
The power unit of the machine is started.
The user waits 4 seconds, after which he closes contact elements 1 and 2 on the connector. Over the next few seconds, the LED will begin to display two-digit codes. The user must count the number of flickers that occur in each series, and also write down the resulting combinations.
DTC, EEC and other system error codes are displayed continuously as long as the vehicle engine is running.

If a Ford car is equipped with a catalytic converter, then diagnostics using a jumper in the car will not work.

Description of error codes

Without special help, it is difficult to decipher the codes that appear. To help the owner of FordFocus 2, a table is offered that explains the meanings of the codes in Russian that indicate problems with your car.

Design and repair of the rear suspension of Ford Focus 1

All error codes that are generated by the on-board computer of your Ford Focus 2 can be divided into 4 groups:

sensor errors;
car engine problems;
problems in the electrical circuit;
other breakdowns.

Below are the transcripts of the most popular errors, the codes of which are presented by the on-board computer in the Ford Focus 2.

How to reset errors?

Removing an error code from the memory of the Ford control unit is allowed only after the fault has been eliminated, otherwise the problem will remain.

There are three options for resetting combinations:

Using a diagnostic tester. The device has a special button that allows you to erase information.
Using a battery. The negative terminal is disconnected from the device for 30 s, after which it is connected back. However, this should only be done with the power unit turned off but warmed up.
The control microprocessor can independently delete error codes after a certain time after they have been eliminated. This occurs when the module is calibrated.

Errors that indicate malfunctions of sensors of different systems

P0100 - P0105 - correspond to an incorrect signal received from the air flow monitoring device, or its breakdown.
P0106 - P0108 - report incorrect operation of the sensor that controls air pressure, and, in addition, an inappropriate signal from the device to the on-board computer of your Ford Focus 2.
P0110 – P0114 – the on-board computer receives incorrect data from the incoming air temperature sensor, indicating a malfunction in its operation or a malfunction of the device, and the need to change it.
P0115 - P0118 - an incorrectly detected signal from the antifreeze temperature sensor, indicating a malfunction or breakdown of the device, which can be eliminated by checking the quality of the corresponding fluid in the system or replacing a malfunctioning device.
P0120 - P0123 - indicate the need to check or replace sensor “A”, which controls the location of the throttle valve of your car.
P0130 – P0167 – error codes that describe the on-board computer receiving an inappropriate signal from the oxygen sensors. The codes indicate that at least one of the three devices is out of order or not working correctly. As a rule, an error requires a more detailed diagnosis of components with the possible subsequent replacement of failed units.
P0176 - P0179 - appear on the monitor if an incorrect signal comes to the system from the emission sensor. The problem can also be resolved by installing a new device.
P0180 - P0188 - report a breakdown of the fuel temperature monitoring device. A more detailed study and diagnosis of the problem will help identify which of the two sensors is the problem and whether it is worth changing.
P0190 - P0194 - it is necessary to check the fuel pressure sensor in the fuel rail and, if necessary, replace it with a new one.
P0195 - P0199 - they say that the device measuring the temperature of the engine fluid does not work; errors may also indicate the presence of a short circuit or possible breaks in the circuit.
P0220 – P0229 – interruptions in the operation of the throttle position sensor “B” or “C”.
P0235 – receipt of an incorrect signal from the turbocharger pressure sensor. If an error occurs, it is recommended to diagnose the circuit for opens and short circuits.
P0236 – P0242 – error codes warning about the need to replace the sensors of the first and second turbines.
P0326 - P0329 - the knock sensor transmits an incorrect signal to the FordFocus 2 on-board computer, indicating the need for additional diagnostics or replacement of the unit.
