Once we have diagnosed the issue, our experienced mechanics can offer you a fast and affordable Ford Wrench Light repair solution. Let’s explore the Ford Wrench Light and our approach to repairing it. 

If you have further questions, contact Branch Automotive today. 

What Is the Ford Wrench Light? 

The Ford Wrench Light is a dashboard indicator used exclusively on Ford vehicles. This light can be triggered whenever your onboard diagnostics II(OBD II) system detects a throttle control system or transmission-related problem. Contrary to popular belief, the Ford Wrench Light can save you money and help you remain safe by alerting you of a potential problem. 

However, you should never ignore the Ford Wrench Light. If you see this dashboard indicator, you should have your vehicle diagnosed as soon as possible by the experts at Branch Automotive. Failure to do could turn a minor problem into a much more expensive affair or cause your vehicle to go into Limp Mode. 

What Is Limp Mode?

Ford Limp Mode, also known as “safe mode” or “reduced power mode,” is a safety feature on Ford vehicles that helps protect the engine and transmission from damage. When a Ford vehicle enters Limp Mode, it limits the engine RPM and slashes power to the wheels, which can make it impossible to drive at normal speeds. The only way you can take your vehicle out of Limp Mode is to repair the underlying problem. 

What Are Common Ford Wrench Light Triggers? 

The Ford Wrench Light can be triggered by many problems. However, the underlying cause will usually be related to your transmission or electronic throttle control system. Some of the most common reasons your Ford Wrench Light is on include: 

  1. Faulty throttle body
  2. Transmission issues
  3. Failed sensors
  4. Electronic control module (ECM) failure
  5. Low battery voltage
  6. Loose or damaged electrical connections

What’s the Process for Ford Wrench Light Diagnosis? 

Once this dashboard indicator is illuminated, you will need a comprehensive Ford Wrench Light diagnosis by Branch Automotive. The most common steps involved with performing Ford Wrench Light diagnosis include: 

  1. Connect diagnostic scan tool: As the first step in Ford Wrench Light diagnosis, we will connect your vehicle’s OBD II to our state-of-the-art diagnostic scan tool. We will retrieve the diagnostic trouble codes (DTCs), which offer additional information about the issue that triggered the wrench light.
  2. Inspect sensors and connections: Once we have the DTCs, our mechanic will inspect the sensors and connections related to the transmission or throttle control system to ensure proper function. 
  3. Test the throttle body: If the issue is related to the electronic throttle control system, we will test the throttle body to ensure proper performance. 
  4. Test the transmission: If the problem is related to your transmission, we will inspect and test this component, including solenoids, torque converter, and valve body.
  5. Inspect the wiring harness: Depending on the cause, we may also inspect wiring harnesses to ensure no damaged connections or wires. 

While most people assume Ford Wrench Light diagnosis only includes connecting the scanner to your ODB-II, there are several additional steps that require training and expertise. Failure to explore all factors can result in misdiagnosis. Simply put, the DTCs —alone— don’t provide sufficient information. 

What’s the Process for Ford Wrench Light Repair? 

Once we isolate the underlying cause, our Ford mechanics will perform the necessary repairs. These repairs may include replacing parts like the:

  • Throttle body, 
  • Throttle position sensor, or 
  • Accelerator pedal sensor. 

Next, we will clear the codes from your vehicle’s computer system. Clearing the codes will turn off and reset your Ford Wrench Light and allow your vehicle to perform normally. The last step involves a test drive where we will: 

  • Ensure the initial issue is resolved,
  • Make sure the Ford Wrench Light doesn’t come back on,
  • Examine the performance of your vehicle, and
  • Make sure no other issues are present.
