Computer diagnostics of errors in Chevrolet Cruze, codes and decoding

When strange numbers or symbols appear on the Chevrolet Cruze instrument panel, this means an error due to a car malfunction, which is important to be able to decipher, reset and correct the condition of your vehicle. With each new version of the Chevrolet Cruze it becomes more and more difficult to read the codes, because... their number increases significantly. But let's look at how to behave in a situation where an error appears on the panel, how to clear the code yourself, when computer diagnostics of a car at a service station cannot be avoided, what PC programs will help you with self-diagnosis and a complete list of codes for the 2014 Chevrolet Cruze.

What to do when the main error messages come on

Symptoms of malfunction

The main driver symptom of P0123 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”.

They can also appear as:

1. The “Check engine” warning light on the control panel will light up.
2. Unstable or low idle speed.
3. Increased engine speed at idle.
4. The engine stalls or has trouble starting.
5. The motor does not operate smoothly (pulsates).
6. There is no response to the gas pedal.

Other symptoms may also be present.

How to Troubleshoot or Reset Trouble Code P0123

Some suggested steps to troubleshoot and fix error code P0123:

1. Read all stored data and error codes using an OBD-II scanner. To find out when and under what circumstances the error appeared.
2. Clear the error codes from your computer's memory and test drive the vehicle to see if the problem reappears.
3. Visually inspect the electrical wires and connections related to the throttle position sensor “A” for looseness or damage.
4. Compare the readings of the throttle position sensors “A” and “B” using a scanner, and if necessary, replace the faulty sensor.
5. Clear the error code from your computer memory again and test drive the vehicle to find out if the problem is resolved.

Decoding error code 89 in a Chevrolet Cruze

Hello! I have a 2013 Chevrolet Cruze. It gives an error: code 89. Help me figure out what this means! (Michael).

Mikhail, hello, we have analyzed your question and are ready to answer it.

What does code 89 mean?

This error code can be called a disease for Chevrolet Cruze cars. Over the past few years, hundreds of motorists have encountered this problem. We have turned to an official source for help with your question. Here's what we learned: combination 89 means the need for vehicle maintenance. Regardless of the mileage on your car, unfavorable conditions for operating a Chevrolet Cruze may periodically arise. It is these conditions that cause the need for maintenance.

Red Chevrolet Cruze

Unfortunately, the manufacturer does not provide more specific information to solve this problem, and it is clear why. Who wants to lose extra money? Diagnostics from an official dealer costs about 600-800 rubles, and this is only the test itself, without solving the problem. Plus, you must come to the “official” with a burning “check” of the error. But in practice, code 89 tends to appear and disappear on the screen. Therefore, if you decide to be serviced by a dealer, then you need to go to him when the code is always on, without disappearing. Of course, this option is not the most acceptable, but, unfortunately, the Chevrolet concern has determined such a car diagnostic policy.

Everyone knows that service at the dealer in most cases costs a pretty penny. We can recommend another option: diagnose your vehicle yourself. To do this, you will need a laptop with the necessary software for this and a special adapter for testing. The laptop is connected via an adapter to the diagnostic connector (its location is indicated in the service manual), and the diagnostic procedure is launched on the computer. The program reads all fault codes and displays them on the screen. In this case, the codes will not be two-digit and can be deciphered using technical documentation. And based on the information received, it will be possible to draw some conclusions.

But keep in mind that in this case you can save money only if you do the diagnostics yourself. If you contact specialists at any service station, the cost of the inspection will cost approximately the same amount that you will need to pay to the dealer. Therefore, how to act in such a situation is up to you to decide.

Diagnosis and problem solving

Carefully check the Throttle Position Sensor (TPS), wiring connector and wiring for opens, etc. Repair or replace as necessary to resolve P0123.

Check the voltage at the TPS (see your vehicle's service manual for more information). If the voltage is too high, this indicates a problem. Replace the sensor if necessary.

If recently replaced, the TPS may need to be adjusted. On some vehicles, installation instructions require proper adjustment (see repair manual for details).

If there are no symptoms, the problem may be intermittent and cleaning the code may temporarily resolve it. In this case, you should definitely check the wiring to make sure that it is not rubbing, worn out, etc.

Fuel system

There are several weak points in the fuel system that can make the power plant unable to start. The reasons for their failure are most often associated with the use of low-grade fuel. Typical fuel system problems are shown in the table below.

To eliminate a malfunction in the fuel system, it is recommended to first check the condition of the fuel injectors. If diagnostics show a violation of the spray pattern, then ultrasonic cleaning is recommended.

It is also necessary to check the condition of the fuel pump and fuel filter. The Chevrolet Cruze does not have a special access hatch under the rear seats, so the gas tank will need to be removed. During this event, you can assess the condition of its internal walls and visually check the quality of the filled fuel.

Before writing why the Chevrolet Cruze won’t start, I thought about describing serious problems. However, after reading the Chevrolet Cruze Club forum, I realized that people do not know the most basic things, and car owners are faced with problems that it is indecent for a more or less experienced driver to even talk about. So let's begin.

Frequently asked questions about auto diagnostics via a computer or smartphone
