Your car whether it’s Renault Scenic, Koleos, Laguna 3, or Trafic needs to be serviced if the warning message “Check Injection System” appears on the dashboard. We have discussed the potential reasons for the message on your car as well as how to resolve it in this guide.
What Does “Check Injection System” Mean in Renault?
When the engine management system stops working, a generic warning message known as the Check injection code appears on a Renault. Generally connected to the fuel injection system’s parts, such as the fuel pump and injectors. An improperly functioning injection system can lead to many problems such as smoke coming from the exhaust and power outages. The warning notice is not to be ignored, and the car should be taken to a technician for diagnostic and repair.
6 Main Causes Behind the Check Injection System Renault
If you want to know what are the causes behind the Renault traffic check injection system message on Renault then read below:
1. Battery Problem
A failing battery is one probable reason for a “check injection system,” based on our experience. It has the potential to result in several electrical issues as well as power outages. An old battery might not be able to provide your car with enough power to run it well. If your Renault’s lights dim or flicker when you turn it on, or if other error messages appear you can determine that your car’s battery is the source of the problem.
2. Mass Air Flow (MAF) Sensor Error
The Mass Air Flow (MAF) sensor is an essential part of the engine control system of a car. It transmits data to the engine control unit (ECU) about the volume of air entering the engine’s intake manifold. To maintain the ideal air-fuel ratio for effective combustion, the ECU analyses information from the MAF sensor to determine how much fuel should be injected into the engine.
3. Bad MAP Sensor
The MAP sensor, which keeps an eye on the air intake, is located inside the engine. It transmits data to the ECU, which utilizes it to regulate the timing of fuel injection. The most frequent issues with this part are that it has a poor electrical connection or separates from its harness.
4. Insufficient Fuel
The “Check Injection System” warning light could come on if the gas tank is low or empty. Keeping the fuel tank enough filled is essential to shield the fuel injection system from harm.
5. Faulty Exhaust Pressure Sensor
Another reason is a faulty exhaust pressure sensor. The gas pressure between the PF (particulate filter) intake and exhaust (outtake) is measured by the exhaust pressure sensor. If this sensor malfunctions, the ECU will think that the exhaust system is leaking. This causes the engine control unit to enter limp mode, which limits speed and usually causes you to lose power when accelerating.
6. Unclean Fuel Injectors
The valves responsible for controlling the fuel flow into the engine are called injectors. Their ability to inject the necessary amount of fuel will be limited if they are unclean or obstructed by carbon buildup. Poor acceleration and a loss of power can result from this.

How to Fix the “Check Injection System” Message on Renault
Here are some of the solution
1. Use Renault Clip to Conduct a Diagnostic Test
A diagnostic tool called Renault Clip is available for Renault cars whether it’s Captur, Fluence, or any other, and it can read and interpret engine management system error codes. An automotive expert can perform a diagnostic test using the Clip and the vehicle’s OBD (On-Board Diagnostic) connection to identify the exact problem causing the “Check Injection System” warning.
2. Check the Wiring And Injectors
The wiring connecting the injectors to the engine control system or the injectors themselves could be the source of injection problems in Renault automobiles. Incorrect operation of one or more injectors can result in power outages, smoke emissions, or uneven fuel distribution. In the same way, communication problems between the injectors and the engine control system can result from faulty wiring or connections.
3. Examine The Fuel Pump And Tank
Low petrol pressure or an improperly functioning fuel pump are two potential causes of the “Check Injection System” notice. If the fuel pump is not supplying enough petrol to the engine, it can result in issues like rough running, smoke emissions, or a lack of power. To identify and resolve the problem, make sure the fuel pump is operating properly and that the fuel tank has enough amount of fuel.
Final Thoughts
A certified mechanic or a Renault service center must evaluate the car when the dashboard displays the warning “Check Injection System”. Diagnostic trouble codes (DTCs), which are frequently kept in the ECU of modern cars, can assist in identifying the precise problem.
