Why Is Engine Fault Repair Needed?

Why Is Engine Fault Repair Needed

It is a warning that the engine is not functioning properly when Peugeot displays “Engine Fault Repair Needed”. An emission control system issue or simply a need for an oil change could cause your vehicle to display the error on the dash. There are many reasons your vehicle could display this error.

This message is most commonly caused by:

Engine Fault Repair Needed Peugeot Causes

Your Peugeot car may be suffering from one of these common engine problems if it keeps telling you that your engine is faulty:

Failure of the high-pressure fuel pump

Failure of the high-pressure fuel pump is the most common cause of this light. Fuel is supplied to the engine under high pressure via the high-pressure fuel pump in the engine bay.

An engine that does not start or run properly, the check engine light or difficulty accelerating are the most common symptoms of a failing high-pressure fuel pump

High pressure fuel is delivered to the engine through this part of the vehicle. Failure to do this will result in the check engine light flashing and the car not starting. As soon as possible, you should resolve this issue because if left unattended, it can severely damage other engine parts.

A bad spark plug or ignition coil

Your engine relies on these two parts to ignite the gasoline so that it can burn properly within its cylinders. Usually, they are located near one another on the top of the cylinder head, which in turn is located directly above the position at which your pistons will be located inside your cylinders, which is what we refer to as the cylinder head.

It will also be difficult for your car to start (even after replacing them) or perform at its best if these parts become damaged or malfunction. As a result of this issue, you might also experience smoke coming from your Peugeot’s hood, or your engine light misfire, resulting in power loss.

Faulty recirculation valve

It is possible for the “engine fault repair needed” message to be displayed due to a faulty recirculation valve. An air flow control valve is located on the side of the engine near the air filter and controls the flow of outside air into the engine bay.

In addition to losing power and making your car difficult to start, a faulty valve can also cause a rough idle. The recirculation valve of your heater or air conditioner could need to be replaced if you hear rattling when you turn it on.

Battery failure

Having a dead battery means your car’s computer can’t receive power, which in turn means other components can’t communicate. In the result, when you turn on the engine, you’ll see an error message.

Turbo failure

Boosting the amount of air entering an engine is accomplished using turbochargers. As a result, fuel is able to be added to the engine more efficiently, thus producing more power for the same amount of fuel consumed. Your engine fault code may be caused by a problem with the turbocharger, which is driven by exhaust gases from inside your engine.

Low engine oil

If the oil level is low, the engine can overheat, causing pistons and cylinders to be damaged. If you cannot change the oil yourself and have an older Peugeot, keep an eye on the oil level regularly. You should check other possible causes of the “Engine Fault Repair Needed” message if you are sure that your car has enough oil.

A faulty camshaft position sensor

Each cylinder is monitored by the camshaft position sensor, so that each cylinder’s ignition timing can be adjusted accordingly. The engine fault message displayed on your dashboard will indicate that you need to repair the camshaft position sensor if the sensor is bad.

Clogged catalytic converter

It is almost certain that if your catalytic converter becomes clogged over time, it can cause poor fuel economy problems, performance problems, and may even damage your ignition coil over time if left unattended. Your catalytic converter needs to be repaired if you receive an “Engine Fault Repair Needed” message.
