Engine Fault Repair Needed Peugeot Causes

There are several common engine problems that your Peugeot car may have if it keeps telling you that your engine is malfunctioning:

Failure Of The High-Pressure Fuel Pump

In most cases, this light indicates a problem with the high-pressure fuel pump. Within the engine bay, a high-pressure fuel pump supplies fuel under high pressure to the engine.

Symptoms of a failing high-pressure fuel pump include difficulty starting or running the engine or the check engine light

The vehicle’s engine receives high-pressure fuel from this part. In the absence of this step, the check engine light will flash and the car will not start. Please resolve this issue as soon as possible, as if left unattended, it could severely damage other engine components.

A Bad Spark Plug Or Ignition Coil

The two parts of your engine ignite the gasoline inside its cylinders in order to burn it properly. It is typically located on top of the cylinder head, which is located directly above where the pistons will be positioned inside the cylinders, and which is also called the cylinder head.

If these parts become damaged or malfunction, your car will also have trouble starting (even after replacing them). In addition to experiencing smoke coming from your Peugeot’s hood, you may also experience power loss as a result of engine misfiring.

Faulty Recirculation Valve

There is a possibility that the “engine fault repair needed” message will appear if the recirculation valve is faulty. Controls the flow of outside air into the engine bay through an air flow control valve located on the side of the engine near the air filter.

You may lose power and have difficulty starting your car when you have a faulty valve. A rough idle may also result from a faulty valve. If you hear rattling when your heater or air conditioner is on, you may need to replace the recirculation valve.

Battery Failure

Dead batteries prevent your car’s computer from receiving power, which inhibits other components from communicating. You’ll see an error message when you start the engine.

Turbo Failure

With turbochargers, air is pumped into an engine at a higher rate. This allows fuel to be added more efficiently to the engine, which produces more power for the same amount of fuel. Turbochargers are driven by exhaust gases from inside your engine, which could cause your engine fault code.

Low Engine Oil

A low oil level can cause the engine to overheat, damaging the pistons and cylinders. If you can’t change the oil yourself and own an older Peugeot, you should monitor the oil level regularly. In case your car doesn’t have enough oil, you may need to check other possible causes.

A Faulty Camshaft Position Sensor

An ignition timing adjustment can be made for each cylinder using the camshaft position sensor. In the event that the camshaft position sensor is bad, you will see an engine fault message displayed on your dashboard.

Clogged Catalytic Converter

Clogged catalytic converters can cause poor fuel economy, performance problems, and may even damage your ignition coil if left unattended for an extended period of time. You need to repair your catalytic converter if you receive a message that says “Engine Fault Repair Needed.”.
