What is an engine failure hazard in Renault?

This error shows on the vehicle’s dashboard when the car’s computer system, engine control unit (ECU), or sensors detect an engine-related fault. It shouldn’t if you didn’t ignore this fault because it can affect the engine performance badly. Various faults like engine injector faults or faulty sensors might cause this warning.

How to fix the engine failure warning?

Fixing the engine failure issue might be difficult for a man who doesn’t have any mechanical knowledge. However, I will guide you quickly so you can fix it without any mechanic help or service. However, three significant factors mainly cause this error, explained in the video below.

Check coolant system
Check fuel injector
Check battery condition

First, there might be a problem with the coolant system or a coolant temperature sensor that’s loose or damaged. Check nearby parts, such as the radiator and examine hose connections. If you find its leakage, then repair it properly.

Secondly, check the fuel injector to see whether it delivers fuel. If it is not working, then first clean it and try it. In the end, if it still shows a fault, then replace it.

Thirdly, check the car battery because it may trigger the fault codes related to the battery voltage. Be sure to replace the battery if it is 3 to 4 years old or genuine because it becomes weak with time.

After watching the above video, I hope your problem has been resolved. If you’re still facing it, read the article below for a detailed overview of engine failure hazards in Renault vehicles.

Moreover, here is a comprehensive explanation of other possible causes and solutions.

Causes of engine failure hazard

Here are some common causes that can lead to that problem:

Overheating
Thermostat malfunction
Oil contamination
Oil issues
Sensors faults
Electrical issues
Software glitches
Faulty spark plug
Coil pack issues

Overheating

The first and most common factor that causes the engine failure hazard warning is overheating the engine due to filter and coolant leaks. Coolant fluids play an essential role in maintaining the engine’s temperature, which protects it from overheating.

Alternatively, depletion of coolant fluids or leaks of coolant can cause the engine temperature to increase, leading to overheating. However, the engine management system detects whether the engine is standard or not, and in case of overheating, it will indicate it with a symbol on the Renault dashboard.

Thermostat Malfunction

A malfunctioning thermostat or a clogged radiator can cause engine damage and will also affect other components. When the engine temperature exceeds or falls, the thermostat maintains and regulates it.

It also controls the flow of hot and coolant water through the radiator. A faulty thermostat will not function properly and will increase the engine heat level, causing failure hazard issues.

Oil Contamination

The oil becomes contaminated or dirty when Renault vehicles are not regularly repaired and maintained. Additionally, poor quality oil and faulty oil filters that are not manufacturer-recommended will contaminate the oil, affecting engine performance and the exhaust system.

Oil Issues

Oil fluids help to maintain engine temperature and improve its acceleration. However, these oils need to be changed after a specific interval recommended by the technician. Several oil issues, like oil leaks from different points such as seals, oil pans, and low oil fluid levels, can also trigger the hazard warning.

Low Engine Oil Level

Low engine oil level is one of the worst things that badly damage the engine efficiency. It is mandatory to check engine oil daily before starting the Renault to ensure that oil levels are up to the top. In case of low fluid level, top it up quickly and always use high-quality oil that the mechanic suggests.

Sensor Faults

Sensors like oxygen control and monitor exhaust systems, petrol, diesel, and gas emissions. A faulty or malfunctioning mass airflow and oxygen sensors will not work correctly and send the incorrect signals to the engine control unit.

Electrical Issues

Electrical issues like damaged wires, loose connections, and malfunctioning electrical system control the engine’s electrical errors. Sometimes, loose connectors trigger issues that can easily detected with a scan tool that helps to diagnose the current critical issues.

Software Glitches

A glitchy or malfunctioning, old system couldn’t work correctly because of poor maintenance service. A bug in the automotive software will cause complex and critical errors.

Faulty Spark Plug

A faulty or fouled spark plug can trigger the error warning light on the Renault car’s dashboard. An incorrect low-quality spark plug not manufacturer-suggested can also lead to misfires or weak ignition.

Electrical issues in the ignition system, such as a weak battery, damaged spark plug wires and the gap between electrodes, will affect the performance of spark plugs.

Coil Pack Issues

Due to sudden voltage spikes in the electric coil pack, internal components will be damaged, resulting in weak or no spark in the ignition system. Additionally, it would help if you took care of the internal ignition system because water can trigger the electric shorts or ignition system damage when water enters it.

Diesel particular filter blockage

If you own a Renault based on a diesel engine, its filter blockage will have a solid lousy impact on the engine efficiency. It may indicate an hazard issue in your Renault vehicle. A blocked/clogged DPF will reduce the quantity of diesel, which will also reduce car performance.

Engine management system faults

EMS is responsible for monitoring and controlling the whole engine in a car. It is also called the brain of a vehicle. It controls the timing of the ignition system, when it will supply the spark to the engine and when it will break the ignition supply. It also monitors the fuel injector whether it is functioning correctly or not.

Solutions to engine failure hazard

To fix the engine failure errors to hazard on your Renault, follow the breakdown solutions:

Regular oil changes
High-Quality oil filters
Oil leak fixing
Timing belt replacement
Fuel system cleaning
Spark plug replacement
Software updates
Regular diagnosis
Inspect electrical wires
Faulty sensor replacement

Regular Oil Changes

Regular and routine maintenance service of changing the engine oil is essential to the vehicle’s condition and is more reliable. Additionally, try to use the suggested oil that has better quality and is a time performer, which will also maintain the temperature in the engine.

High-Quality Oil Filters

Always use a high-quality oil filter because it will remove contaminant particles from the oil and last longer. Additionally, change the old oil filter when getting regular vehicle maintenance service.

Oil Leak Fixing

Keep an eye on the oil leaks because a minor can cause immense damage to the engine. So, ensure that all the components are cleared from leakage. Inspect and replace the elements like the coolant system, oil filters, hoses, and water pump found in leak condition.

Timing Belt Replacement

When your vehicle has covered a distance of 60,000 to 100,000 miles, you should change the timing belt early to avoid any fear of damage. Timing chains perform longer than timing belts but inspect them to ensure they are in good condition and don’t need any replacement.

Fuel System Cleaning

Regularly clean the fuel system components like fuel injectors to prevent clogging and blockage. However, replace those that can’t be repaired or resurfaced for use again.

Spark Plug Replacement
