Engine light that lights up on my Citroen Jumper, what should I do?

You have been driving peacefully for half an hour when suddenly the engine light begins to light up on your dashboard. Several cases are available to you when this is the case, we will identify and analyze them in order to help you. Before starting, it is important to know that in the vast majority of cases, an engine light that comes on represents a major problem on your Citroen Jumper so be very careful.
First of all, you need to know what problem you are facing and in particular the seriousness of it. This can be determined by the behavior of the engine light of your Citroen Jumper, according to the different categories listed below. So refer to the corresponding situation to act accordingly.

Different options when the engine light comes on on your Citroen Jumper

Get to the garage as soon as possible with your Citroen Jumper:

  • The engine light comes on and goes off, or flashes : The causes can be multiple, but it is important to go and check this at a garage.
  • The indicator light comes on and stays on : this most likely comes from the antipollution system which has anomalies, it is better to go to a garage nearby.

Stop your Citroen Jumper as soon as possible and call a mechanic for towing to the garage, no need to take risks by driving with:

  • Engine light stays on and car has performance issues : If a serious problem is detected by the onboard computer of your Citroen Jumper, the security mode is engaged. This therefore allows you to drive in degraded mode (loss of available power), which saves you from major problems (engine failure). In this situation, we strongly recommend that you call a garage for your Citroen Jumper.
  • The LED stays on AND blinks : This situation presents the greatest risk. This means that the catalytic converter is overheated because it is damaged, which means that at any time it can ignite. Stop your car urgently.

Probable causes of the engine light on your Citroen Jumper

The possible causes of failure of the engine management system of your Citroen Jumper are multiple, but divided into 2 groups:

  • Hardware problem : injection system (vacuum hoses, flowmeter, injection pump, turbo), antipollution / emissions control system (EGR valve, catalytic converter), etc.
  • Electronic problem : defective or disconnected sensor, lambda probe to be changed, computer, etc.

All the causes that could cause the engine light to come on on your Citroen Jumper

Then there may be a problem engine injector clogged on your Citroen Jumper. We therefore recommend that you clean it. It will operate as usual, but air and / or fuel will have difficulty circulating.

Un faulty injector on your Citroen Jumper can potentially send too much fuel and cause over pollution which will result in clogging of the catalyst (+ DPF (Particulate Filter) on diesel).
If ever catalyst of your Citroen Jumper was too dirty, (there is no longer the right balance of chemical components which gives the possibility of transforming the exhaust gases) of any logic the warning light will come on.
Same if the injection pump has a particular concern. Its role is to better control combustion, and therefore the consumption of an engine. Directly linked to the engine, if it were to stop working, the warning light on your Citroen Jumper would come on as well.
In addition, if your Lambda probe no longer works, it will no longer be able to check the exhaust gases of your Citroen Jumper and the computer will therefore no longer be able to modulate the injection in order to be able to reduce emissions.
If your Citroen Jumper has a petrol engine, an ignition problem (coils or spark plugs) can induce an increase in pollution and therefore the engine warning light coming on.
Also, a overheated catalyst (if you were driving more aggressively, or the presence of fuel in the exhaust line which heats everything) can potentially turn on the engine light of your Citroen Jumper.
Un throttle position sensor (unit whose mission is to channel the volume of air entering the engine) no longer allows the computer to produce a balanced mixture between fuel and oxidizer (an oxidizer is a chemical substance which has the property of allowing the combustion of a A suitable mixture of oxidizer and fuel can cause combustion): Combustion no longer takes place correctly and the engine is disturbed, which causes the ignition of the engine warning light of your Citroen Jumper.

A clogged DPF (Particulate Filter) can also cause the engine warning light to come on, but usually another warning light representing the filter also lights up.
Un poor quality or unsuitable fuel (this sometimes happens with the E10) may cause this light to come on on your Citroen Jumper. It can then go out on its own once you have put another fuel in your Citroen Jumper. This can happen right after an unusual pump change. If you always take fuel from the same place, ask the person who manages the gas station.
A dirty engine can turn on this light. Indeed, soot can reduce the tightness of certain parts of the engine (eg: clogged valves which no longer ensure perfect sealing of the cylinders of your Citroen Jumper).
A blocked EGR valve (usually by soot) sends too much of the exhaust gas back into the engine, combustion is therefore disturbed and is no longer under control: the engine warning light on your Citroen Jumper comes on.
Also involved, injector leaks. There are several types, depending on whether your Citroen Jumper runs on diesel or petrol: For petrol Citroen Jumper, the leak is located on the upper or lower part of the engine injector. With regard to Citroen Jumper diesel, the leak may be located at the arrival, the base, or at the injector return hose.
Finally, the injector may also be clogged. If this is the case, it is possible to clean it yourself. There are different solutions to perform the manipulation. However, the operation can be meticulous, we advise you to seek professional help or replace it if you also notice signs of wear.
Here are the main causes of the engine light of your Citroen Jumper coming on, as you have noticed, this concerns sensitive parts of your vehicle, do not take any risk with regard to this light this can have serious repercussions. .
