Ford Fiesta Wrench Light: What Does It Mean?
A Wrench light Ford Fiesta means a powertrain failure.
If illuminated, it indicates that the computer in the system has detected a malfunction with the vehicle’s four-wheel driving (4WD) system.
This dashboard Wrench warning light can also originate from problems related to powertrain components, such as transmission, engine, or driveshaft.
If your Ford Fiesta sends you this warning light, it requires regular maintenance, such as oil and filter changes.
You should check your system with the support of an authorized dealer in your area.
In addition, this Wrench warning light illuminates periodically related to mileage needs to reset after proper maintenance.
Ford Fiesta Wrench Light: How To Fix?
First, the vehicle may have severely limited acceleration or transmission shifts, so you must pull it over.
Even if the Check Engine Light is not illuminated, the computer may have stored diagnostic trouble codes (DTCs). A pending code will not trigger the Check Engine Light.
Thus, you can get this code if you own an OBD scan tool. Your local parts store will help you scan your computer if you don’t have one.
The engine’s performance has deteriorated; having the stores cannot be easy.
After I turned the engine off and restarted it after a while, the Wrench light went out, and your vehicle then started and ran as normal.
Yet, if the problem persists, the lights can come back on. That’s why it’s critical to scan your computer and address the DTCs soon.
I usually solve the problem temporarily by restarting your engine.
Doing so is a great way to turn off the Wrench light on Ford Fiesta as long as there are no other hidden problems.
Why Does Ford Wrench Light Come On?
Numerous reasons can cause the Wrench light Ford Fiesta to appear on the screen dashboard. There can be problems with the battery, faulty kit wiring, or damaged carburetor.
Besides, the Ford Wrench light also comes on if the transmission gets troubled or the throttle has issues.
So, you can take a deep look at the root causes of the illuminated Ford Fiesta light.
Battery Issues
The Ford Wrench light comes on when messed up or the battery is low. A dead battery can also lead the Wrench warning light on the dashboard to keep flashing.
Thus, a spare battery is the simplest method to confirm if you have a bad battery. I replaced the dead battery with low voltage in less than an hour when detecting any problems with it.
Kit Wiring Damage
A kit of wires in the car is important in connecting to the car’s computer to ensure the constant operation of the system.
Minor damage to your car’s wires may ruin electrical components inside the vehicle.
Besides, a loose connector may also force the automotive computer to display an error code and the Wrench light to illuminate.
Carburetor Problems
A broken or failing carburetor is another culprit behind the flashing Wrench light on the Ford Fiesta’s dashboard.
If there is a failure with the carburetor, the engine overheats, and the Wrench icon flashes. I just did a carburetor cleaning and could start the engine again.
Yet, if the failure persists, you should bring your car to your nearest auto shop or car service center. The expert mechanics will check the problems and rebuild the carburetors.
If the carburetor fails, replacing it with a new one is the best way.
Oil Change Due
A yellow light on a Ford Fiesta vehicle indicates that the oil in your Ford vehicle needs a change. Ford also recommends changing the oil every 3 months.
You must do it accordingly to maintain your vehicle running smoothly. Normally, the light can go off after an oil change.
Throttle Problems
The throttle issue also interferes with the Wrench light. The lights flicker whenever you start your vehicle. The vehicle’s Wrench light may also flash when you park your vehicle in the garage.
Besides, the Electronic Throttle Body (ETB) may be dirty with carbon deposits. Dirt is blocking throttle plate movement, resulting in inconsistent data in the system.
Clean debris from the throttle before going to the mechanic with a proper cleaner.
Faulty Transmission System
Transmission failure is often the primary trigger of a Wrench light.
Symptoms of this failure include slipping gears, the engine not starting, increased fuel consumption, engine leaking fuel, and making noise.
In this case, the two main culprits are the engine control module (ECM) and the powertrain control module (PCM).
The PCM is in the Ford engine’s heart. It manages the vehicle’s efficient movement and gets data from the engine sensors.
Besides, PCM keeps the engine running at peak performance while using less fuel.
FAQs
Can I Drive With Wrench Light On Ford?
Yes, you can. Yet, Ford’s Wrench lights indicate that something goes wrong in your engine system. Sometimes, the problem is so severe that it reduces the engine’s life.
So, you must take the essential steps to fix them properly instead of keeping driving.
What Are the Differences Between a Check Engine Light and Wrench Light on a Ford?
These two lights can flash at the same time. Both hint at a problem with the Ford Fiesta vehicle. Yet, they have a few differences.
A wrench light is a component in the Ford’s warning system to inform the driver of the powertrain malfunction or a failure in the 4WD system.
Meanwhile, the check engine light is important to all vehicles’ standard onboard diagnostics (OBD) systems. It often flashes to warn of a failure with the emission-controlling system.
How To Make Ford Wrench Light Reset?
- Turn the ignition on, but don’t start your engine.
- Press and hold the brake pedals and accelerator simultaneously for 30 seconds.
- After 30 seconds, the Wrench light will go off.
- Again, addressing why this light is on before resetting is important.
Conclusion
