You’ve been driving for over half an hour when all of a sudden the engine light on your dashboard starts to panic. We will determine all the options and analyze them to help you. First of all, you should know that in most situations, there must be a significant problem on your Ford F 250, so be very careful.
First, you need to figure out what problem you are facing and especially how severe it is. This can be established by the behaviour of the Ford F 250’s indicator light, as outlined by the different categories listed below. Therefore, look up to the right situation in order to react accordingly.


What to do if the engine light is on when using my Ford F 250

Among these options, here are the ones for which you need:

Drive at once to the garage in your Ford F 250 :

– The engine light turns on and off, or flashes: the triggers can be multiple, but you will need to check with a mecanic .

– The light comes on and stays on: this is most likely due to the pollution control system which has faults, so go to a nearby garage.

Stop your Ford F 250 as soon as you can and contact a mecanic for a tow to the garage, do not take chance of driving with it:

– The engine light stays on and the car has performance disorders: If a serious problem is discovered by the on-board computer, the safety mode is activated. This makes it possible for you to drive in degraded mode (loss of available power), which reduces the risk for more serious problems (engine failure). In this situation, we strongly suggest you to use a garage for your Ford F 250.

– The light stays on AND flashes: This is the most dangerous situation. This suggests that that the catalytic converter is too hot because it is damaged, which suggests that that at any time it can ignite. Stop your car urgently.

Probable causes of the ignition of the engine warning light
The potential causes of failure of your Ford F 250’s engine management system are diverse, but categorized into 2 groups:
– material problem: injection system (vacuum hoses, flow meter, injection pump, turbo), emission control system (EGR valve, catalytic converter),…
– electronic problem: defective or disconnected sensor, lambda sensor to change, computer,…

All the causes that could entail the ignition of the engine light on your Ford F 250

There could then be a problem with a dirty engine injector on your Ford F 250. We therefore encourage that you clean it. It will operate as usual, but the air and/or fuel will have problems circulating.

A faulty injector on your Ford F 250 can possibly send too much fuel and cause over-pollution, which will cause the catalyst to clog up (+ FAP (Particulate Filter) on diesel).
If the catalyst of your Ford F 250 is too dirty, (there is no longer the right balance of chemical components to transform the exhaust gases) hence the light will come on.
Ditto if the injection pump has a particular problem.
A HS lambda sensor will no longer be able to check the exhaust gases of your Ford F 250 and the ECU will therefore no longer be able to modulate the injection to reduce emissions.
If your Ford F 250 has a petrol engine, an ignition issue (coils or spark plugs) can lead to increased pollution and as a result to the ignition of the engine indicator light.
Also, an overheated catalyst (if you were driving more aggressively, or the presence of fuel in the exhaust system that heats up everything) may cause the engine light on your Ford F 250 to flash.
A throttle position sensor (a housing that deals with the volume of air entering the engine) no longer enables the ECU to produce a balanced mixture between fuel and oxidizer (an oxidizer is a chemical substance that has the property of allowing a fuel to burn. An appropriate mixture of oxidizer and fuel can lead to combustion): The combustion is not anymore correct and the engine is disturbed, which causes the engine indicator light on your Ford F 250 to light up.

A clogged FAP (Particulate Filter) will therefore also logically be a cause, but usually another indicator representing the filter also lights up in addition.
Poor quality or unsuitable fuel (this sometimes happens with the E10) can cause this light on your Ford F 250 to light up. It can then shut itself off once you have driven with some other fuel. This can happen due to an different pump change. If you are still taking fuel at the same place, ask the person who runs the gas station.
A dirty engine may cause the light to turn on . Indeed, soot can make some parts of the engine less airtight (e.g. val)
