The Ford Focus has been touted as one of the best hatchback models from the Ford manufacturer. It has been incrementally improving the engine with each model and when you see the sports models like the ST and RS, you can see the level of performance force has on offer.

However, the “Ford Focus engine service now loss of power” is something a few drivers have been plagued by.

When your “engine service now” light comes on and your vehicle immediately drops power, it will be a major reason for concern. What tends to happen is the engine will spew out an error code and depending on the severity of the error in the engine, it will go into limp mode, which explains the loss of power.

There are a couple of reasons for this including the clutch slipping and low fuel pressure.

While the best thing you do is to either visit your mechanic or invest in a code scanner to help you identify the codes, the vehicle should not be doing this often.

Having done some solid research, we have come up with a few things that could be causing the sudden loss of power. Unfortunately, the problem rarely occurs at home and often on the road.

Why Does My Ford Focus Read “Engine Service Now & Have A Loss Of Power”?

If you encounter this frustration with your Ford Focus, and you don’t have a code scanner, you will need to take it to a professional mechanic to figure out what is wrong.

Fortunately, we have identified the most common reasons for this rare Ford Focus phenomenon to give you an idea of what could be causing the problem:

1.      Clutch Slipping

Problem: While your clutch slipping is not a common reason for your car to activate the limp mode, it could happen as the clutch damage is aggravated. If your clutch is beginning to deteriorate, you will notice the slipping as you accelerate.

The revs might also climb much higher without the speed of the vehicle changing on the open road. A jerking sensation in the car might also be felt.

Solution: Depending on the severity of the clutch slipping, it could be worn or might only be on the way to wearing out. You will need to discuss this with your dealer or mechanic and hopefully, find the best way forward. One tip we could give you is to change your driving style.

Many manual drivers tend to “ride the clutch”.

If you do however have some experience in repairing cars yourself, then we do have an option to purchase the entire Clutch kit to DIY :

2.      Crankshaft Position Sensor Failed

Problem: While many people have reported that turning the vehicle off and turning it back on has solved the problem, the loss of power is something you should be concerned about.

This could be a variety of reasons for a Ford loss of power, but a crankshaft position sensor or cracked soldering on the cluster panel could also be the reason.

Solution: If you manage to restart your vehicle without issue, it should not be any reason for concern. However, if the loss of power continues, it could be a variety of reasons. You should consider visiting your dealership to have them look over any possible issues.

If you would like to save some cash, you could also potentially purchase the sensor yourself on Amazon and then get your mechanic to install it for you. Check the price out here.

3.      Obstructed Air Filter

Problem: While the obstructed air filter does not activate specific error codes or force the “service engine now” to display, it is one of the reasons your Ford Focus might lose power when you are driving.

The air filter will eventually be obstructed the more you drive without having it cleaned. Once the air pressure is too low, it will cease to ignite the fuel.

Solution: The great thing about an air filter is that it is one of the easiest components to fix. You can take apart the air filter at home and give it a good cleaning. If you notice any damage to the component, you can source a new air filter as a replacement.

Fortunately, this is not one of these hyper-expensive components to fix.

4.      Low Battery Voltage

Problem: Once the battery starts giving you issues, you will notice a host of different things go wrong. However, many of these errors are only on the display and could only give you a good scare.

The battery is responsible for running the electronics of your vehicle. This also means that it controls the onboard computer and software.

Solution: We have noticed that many people who get errors like this only have to give the battery a good charge. Fortunately, you can test the charge of the battery yourself at home. I

f the voltage is too low, it will be one of the reasons for this issue.

5.      Software Bug

Problem: Once you have gone through basic diagnostics, you might take your vehicle to the local dealership.

We have seen a few cases where the code scanners do not turn up any real code and the loss of power is related to the software bug. The issue is most common in the Ford Focus models from 2010-2014.

Solution: If this is a software bug, you have two options. The first option would be to take the vehicle to the dealership and have them reset or update the software on your Ford Focus.

However, by pressing the brake and gas pedal simultaneously, you can reset the dashboard. Keep in mind that you should hold them both for at least one minute to reset.

6. Faulty Oxygen Sensor

Problem: The oxygen sensors in your Ford Focus play a crucial role in controlling the fuel and ignition systems that keep your car running smoothly.

If these sensors are faulty, they can impact your car’s performance, fuel efficiency, and emissions. You might also notice that your “Engine Service Now” light has turned on.

Solution: If you’ve identified or suspect a faulty oxygen sensor, the best course of action is to replace it. These sensors can be purchased independently and replaced with some mechanical know-how, or you can have a professional mechanic do the job.

7. Damaged Spark Plugs

Problem: Spark plugs are essential to your car’s ignition system. If your spark plugs are damaged or worn out, they can cause your car to misfire, decrease your fuel efficiency, and possibly trigger your “Engine Service Now” light.

Solution: To fix this issue, you’ll need to replace your damaged spark plugs. While this can be a DIY task for those with some mechanical skills, you can also bring your car to a professional mechanic.

8. Bad Catalytic Converter

Problem: The catalytic converter plays a vital role in controlling the emissions from your car. If it’s not functioning properly, it can lead to decreased performance, increased fuel consumption, and might trigger your light.

Solution: If your catalytic converter is bad, it will need to be replaced. This can be a costly repair, but it’s essential for your car’s performance and to stay within emission standards. A professional mechanic can perform this replacement.

9. Faulty Fuel Cap

Problem: A faulty fuel cap might not seem like a big deal, but it can lead to a variety of problems with your car. It can cause fuel to evaporate more quickly, potentially causing your car to fail an emissions test.

Solution: Replacing a faulty fuel cap is a simple and inexpensive fix. It can be easily done at home, and the replacement caps can be purchased from many automotive parts stores or online.

10. Faulty Accelerator Pedal

Problem: The accelerator pedal in your Ford Focus controls the throttle valve, which in turn manages the amount of air entering the engine. A faulty accelerator pedal can lead to issues with acceleration, erratic engine behavior, and can trigger the “Engine Service Now” light.

Solution: If you suspect a faulty accelerator pedal, it is recommended to get it checked and replaced by a professional mechanic.

11. Fuel Pump Failure

Problem: The fuel pump in your Ford Focus ensures the right amount of fuel is delivered to your engine. A failure in the fuel pump can result in insufficient fuel supply to the engine, leading to loss of power, stalling, and the triggering of the “Engine Service Now” light.

Solution: A failed fuel pump needs to be replaced. This is a complex job that requires professional skills, and should be carried out by a qualified mechanic.

12. Sensor and Wiring Issues

Problem: Sensor and wiring issues in your Ford Focus can result in incorrect data being sent to the engine control unit (ECU), causing engine malfunction, power loss, and the “Engine Service Now” warning.

Solution: Sensor and wiring issues can be complex and are best diagnosed and fixed by a professional mechanic. If a specific sensor is faulty, it will need to be replaced. Wiring issues might require partial or complete re-wiring.

13. Clogged Fuel Injectors

Problem: The fuel injectors in your Ford Focus deliver fuel to the engine. Over time, they can become clogged, affecting the fuel-air mixture in the engine. This can lead to engine malfunction, power loss, poor fuel efficiency, and the warning light.

Solution: Clogged fuel injectors can be cleaned or replaced. Cleaning can be done using a special cleaning solution, while replacement should be carried out by a professional.
