Check Injection System Renault: Reasons & Solutions

In the case that the “Check Injection System” message appears on the dashboard of your Renault Scenic, Koleos, Laguna 3, or Traffic, you should have your vehicle serviced. Our goal in this guide has been to provide you with potential solutions to the car message and potential causes that may lead to it.


What Does “Check Injection System” Mean In Renault?

Whenever the engine management system stops working on a Renault, the Check injection code appears. There are generally several components of the fuel injection system attached to this part, including the fuel pump and injectors. There are several symptoms of a malfunctioning injection system, including smoke coming from the exhaust pipe and power outages. Your car should be diagnosed and repaired by a technician as soon as possible if you disregard this warning notice.


Keeping Checkups Regular

Maintaining injection systems on a regular basis is crucial to preventing injection system problems. A regular check-up not only helps identify potential problems early, but it is also cost-effective over the long run. Identifying potential problems early can be achieved by performing regular maintenance, according to Renault.


Reasons For The Check Injection System Renault

For further information on what is causing Renault traffic check injection system messages, please see the following:

Battery Problem

“Check injection systems” are often caused by failing batteries. A dead battery can cause electrical problems as well as power outages. A car with an old battery may not be able to perform as it should if it has an old battery. Whenever you turn on your Renault, you may notice that its lights dim or flicker, or other error messages may appear, which indicate a bad battery.

Error With The Mass Air Flow (MAF) Sensor

It is crucial that the Mass Air Flow (MAF) sensor plays a crucial role in the engine control process of a car. A data transmission system informs the engine control unit (ECU) about the volume of air entering the intake manifold. Fuel injection is calculated based on the information collected by the MAF sensor so that the engine can burn efficiently based on an optimal air-fuel ratio.

A faulty MAP sensor

A MAP sensor monitors the air intake on engines. This data is transferred from the ECU to the sensor in order to regulate fuel injection timing. These parts are most commonly damaged by poor electrical connections or separations from their harnesses.

Low Fuel Supply

In some cases, the “Check Injection System” light will illuminate if the gas tank is empty or low. It is essential that the fuel tank is filled with enough fuel in order to ensure proper operation of the fuel injection system.

Defective Exhaust Pressure Sensor

There is also the possibility of a faulty exhaust pressure sensor. A particle filter (PF) pressure sensor measures the difference between gas pressures at inlet and exhaust. It is likely that this sensor will malfunction, causing the ECU to believe that the exhaust system has a leak. Your engine control unit usually enters limp mode when you accelerate, which causes you to lose power.

Dirty Fuel Injectors

A fuel injector controls the amount of fuel that is injected into an engine. A dirty injector or one that has been clogged with carbon will not be able to inject the necessary amount of fuel. In such cases, power can be lost and acceleration can be poor.

Fixing The Renault “Check Injection System” message

Fixing the message that appears when the check injection system is not functioning can be done on Renault models like the Grand Scenic and Kadjar.

Perform A Diagnostic Test Using Renault Clip

In addition to reading and interpreting engine management system error codes from Renault models including Captur, Fluence, and others, the Renault Clip diagnostic tool can also diagnose fuel economy problems. Auto experts can perform diagnostic tests using the Clip’s OBD (On-Board Diagnostic) connection to identify the exact cause of this warning.

Inspect The Wiring And Injectors

There are a number of causes of injection problems in Renault automobiles, either because of wiring between the injectors and the engine control system or because of the injectors themselves. The improper operation of one or more injectors can result in power outages, smoke emissions, and uneven fuel distribution. The communication between injectors and engines can also be interfered with by faulty wiring or connections.

Take A Look At The Fuel Pump And Tank

There may be a problem with the fuel pump or low petrol pressure which causes a notice saying “Check Injection System.”. An insufficient amount of petrol can cause rough running, smoke emissions, and a lack of power if the fuel pump does not deliver enough fuel to the engine. In order to determine and fix the problem, make sure that the fuel pump is working properly and there is enough fuel in the fuel tank.
