Common Questions

What does C073C mean and how does it affect my car?

The C073C code indicates a traction control system malfunction, which can significantly impact your vehicle's ability to maintain traction on slippery surfaces. If not addressed, it may lead to unsafe driving conditions, especially in inclement weather.

What are the most common causes of C073C and how much does it cost to fix?

Common causes include faulty wheel speed sensors, traction control module issues, and wiring problems. Repair costs can range from $100 for wiring repairs to $800 for module replacement.

Can I drive my car with C073C or should I stop immediately?

While you can technically drive your vehicle with a C073C code, it's advisable to address the issue as soon as possible. Driving without a functioning traction control system can be dangerous, especially in adverse weather conditions.

How can I diagnose C073C myself using GeekOBD APP?

Using the GeekOBD APP, you can scan your vehicle's OBD2 system to retrieve the C073C code. From there, you can access freeze frame data to gain insight into the conditions when the error was recorded, helping you identify potential causes.

What vehicles are most commonly affected by C073C?

The C073C code is frequently encountered in 2015-2020 Ford F-150 models, but it can also appear in other similar vehicles from Ford and other manufacturers with traction control systems.

How can I prevent C073C from happening again?

Regular maintenance, including checking the condition of wheel speed sensors and wiring, can help prevent C073C from recurring. Additionally, keeping your vehicle's software updated can mitigate software-related issues.

What is C073C?

The diagnostic trouble code C073C indicates a malfunction in the traction control system (TCS) of certain vehicles, primarily affecting brands like Ford, particularly the F-150 models from 2015 to 2020. This code signals that the vehicle's onboard diagnostic system has detected an issue that could impact the vehicle's stability and handling. The traction control system works by monitoring wheel speed and applying brakes to individual wheels or reducing engine power to prevent wheel spin during acceleration. When C073C is triggered, it often results in the traction control warning light illuminating on the dashboard. Ignoring this code can lead to diminished traction, especially under slippery conditions, increasing the risk of skidding or loss of control. In some cases, additional codes may accompany C073C, providing further insight into the underlying issues. Drivers may experience symptoms such as decreased performance in wet or icy conditions and potential issues with the anti-lock braking system (ABS). Addressing this code promptly ensures safer driving and optimal vehicle performance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C073C is present:

  • The traction control warning light remains illuminated on the dashboard, indicating a system fault.
  • Drivers may notice a decrease in vehicle acceleration, especially on slippery surfaces, as the traction control system cannot engage properly.
  • Unexpected wheel slip or loss of grip during acceleration could be felt, making it challenging to maintain control, especially in rain or snow.
  • The vehicle might exhibit unusual braking responses, particularly when traction is lost, affecting overall driving safety.
  • In some cases, the anti-lock braking system may also show irregularities, leading to a compromised stopping power.

Possible Causes

Most common causes of C073C (ordered by frequency):

  1. The most common cause of the C073C code is a faulty wheel speed sensor, which can occur in approximately 40% of cases. This sensor measures the rotation speed of each wheel and communicates with the traction control system. If the sensor is malfunctioning, the TCS can't operate effectively.
  2. Another likely cause is issues with the traction control module itself, which can account for about 30% of cases. If the module is not receiving accurate data from the wheel speed sensors, it may fail to engage or disengage properly.
  3. Loose or damaged wiring and connectors are also frequent culprits, making up around 20% of the causes. This can prevent the wheel speed sensors from sending the correct signals to the TCS.
  4. Less common but serious causes include a malfunctioning ABS module, which can impact both the TCS and ABS systems, requiring immediate attention.
  5. Rarely, software glitches in the vehicle’s control modules can lead to the C073C code, necessitating a system update or reprogramming.
