Chevrolet Cruze error codes: what the faults on the display mean, explanation

Standard Chevrolet Cruze fault codes are designed to notify the driver of existing faults in the vehicle's on-board circuits. Typically, general codings are displayed on the dashboard. The on-board computer has a self-diagnosis option that allows the car to independently find problems. It is also possible to read codes when connecting an external scanner. This usually makes it possible to find a more accurate solution to the problem on the car. OBD2 data is highly accurate, which is a great help when repairing a car.

Diagnostics

So, an icon with or without an inscription appeared on the instrument panel. What to do - go to a car service? No, you can just look in the service book, where the symbols are written. Here's a breakdown of the icons:

Chevrolet Cruze.

Meaning	Translation	What to do
Change Engine Oil Soon	The time to change the engine oil is approaching (less than 5% service life)	Fill the oil and reset the readings of this resource
Low Engine Oil Level	Low engine oil level	If after filling the oil the message does not disappear, then let the power unit operate in the thermodynamic cycle, because instrument cluster is ok
Oil Pressure Low - Stop Engine	Low engine oil pressure - stop the engine	Bringing the indicator into line
Program Cluster	Program the instrument cluster	Performed after replacing devices or when information appears on the display. the center of such a message. We recommend carrying it out using the SPS system
Service Vehicle Soon	The next vehicle maintenance is approaching	The error is displayed when a problem is detected by the ECM engine control unit
Vehicle Overspeed	Speeding car	Reduce speed

Scanners are used to carry out diagnostics. There are laptops and computers. So, the latter includes a laptop or tablet, from which all operations can be carried out if you have the appropriate software.

Portable or display ones are very expensive, but their operating principle is the same - to identify errors and malfunctions in the electronic engine control unit.

Diagnosis of car faults using a scanner.

After connecting through a special connector, a test scan is carried out, which shows the presence of errors. Based on the errors, you can determine in which node the fault is hidden.

How to Troubleshoot or Reset Trouble Code P2723

Some suggested steps to troubleshoot and fix error code P2723:

Replacing ATF fluid and filter.
Filling transmission fluid to the required level.
Flushing to clean the internal transmission channels.
Testing and, if necessary, replacing a faulty pressure control solenoid valve.
Repair or replace the faulty transmission pump and transmission valve body.
Checking connectors and wiring.
Firmware update or replacement of PCM.

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.

Cause of malfunction	Manifestation
Refueling with low-grade fuel	Almost immediately after visiting the gas station
Fuel injectors	Starting becomes more difficult each time depending on the degree of clogging of the sprayer.
Gasoline pump	Failure to start the engine is usually preceded by a situation where the car stalls while driving.
Fuel filter	Clogging can occur either gradually or suddenly after refueling with low-grade fuel.

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.

Comments and reviews

Precisely a smart one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap ELM type scanner, then it simply may not detect the error! SO, what problems there may be, I’ll start with, perhaps, the most harmless one: But for a couple of people, after replenishing the antifreeze, the errors went away.

Chevrolet Aveo T300 Sensor replacement error 89

I attribute this to the fact that the coolant pipes pass through the throttle; it can be seen that if air begins to appear there, this causes an error. I did the same, my level was really low, but it didn’t help me! The position of the damper differs from the normal angle, the ECU sees this and is visible, therefore errors 84 and It is these conditions that cause the need for maintenance.

Red Chevrolet Cruze Unfortunately, the manufacturer does not provide more specific information on solving this problem, and it is clear why. Who wants to lose extra money?

Diagnostics from an official dealer costs about rubles, and this is only the test itself, without solving the problem. But in practice, code 89 tends to appear and disappear on the screen.

Chip tuning

Some drivers do chip tuning of the Chevrolet Niva in order to increase engine power. The essence of this procedure is to remove the established restrictions by adjusting the optimal factory settings in the electronic control unit. This procedure helps to extract the additional performance inherent in the motor.

The whole process can be divided into several stages:

The main advantage of this procedure is:

The disadvantages include:

Each specialist has a different attitude towards chip tuning, some consider it useful, while others think that this procedure can negatively affect the performance of the car, while reducing its service life.

How to do a self-diagnosis on a Chevrolet Cruze

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 codes, as 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.

Poor or does not start at all when cold

This is a very large layer of faults that have the same symptoms - the Chevrolet Cruze does not start when cold or starts very poorly. There will be several reasons:

The insulation of high-voltage wires is damaged. The treatment option is to replace the wires.
The life of the spark plugs has expired. Elimination - replacement of the candle.
The intake temperature sensor is faulty. Repair - replacement of the sensor.
The air filter is clogged. Not everyone changes the air filter during routine maintenance. In this case, it may become clogged.
The injector is clogged. The treatment option is to clean the injector.
Low quality fuel. This problem can be eliminated by adding good gasoline. If you fill the tank full, you can add an additive to it so as not to spill gasoline.
