The most common cause of C0241 is a faulty left front wheel speed sensor, which typically costs between $150 and $300 to replace. Other causes include damaged wiring, which can cost between $100 and $200 to repair.

Can I drive my car with C0241 or should I stop immediately?

It's not advisable to drive with a C0241 code as it indicates a potential failure in your braking system. Reduced braking efficiency can lead to serious safety risks, so it's best to address the issue immediately.

How can I diagnose C0241 myself using GeekOBD APP?

To diagnose C0241 using the GeekOBD APP, connect the app to your vehicle’s OBD2 port. Retrieve the diagnostic codes and examine freeze-frame data to understand the conditions under which the fault occurred. Check for related codes that might indicate underlying issues.

What vehicles are most commonly affected by C0241?

DTC C0241 is commonly found in vehicles like the 2007-2010 Chevrolet Silverado and GMC Sierra. Owners of these models should be particularly vigilant about potential ABS issues.

How can I prevent C0241 from happening again?

Routine maintenance of your vehicle's braking system, including regular inspections of the ABS components, cleaning electrical connectors, and ensuring the wheel speed sensors are free from debris can help prevent C0241 from recurring.

What is C0241?

DTC C0241 is a diagnostic trouble code that signifies an issue within the Anti-lock Brake System (ABS) of your vehicle, particularly related to the left front wheel speed sensor. This sensor is crucial for monitoring the speed of the wheel, which helps the ABS module determine when to engage and disengage braking to prevent wheel lock-up during sudden stops. When the C0241 code is triggered, it indicates that the ABS module has detected an inconsistency or failure in the left front wheel speed sensor's readings. This can lead to reduced braking efficiency and potentially unsafe driving conditions. Car owners may notice the ABS warning light illuminated on the dashboard, indicating a need for immediate attention. Ignoring this code can lead to compromised vehicle control in emergency situations. In some cases, drivers report a feeling of the brakes pulsing or grabbing unexpectedly, which can be alarming and dangerous. If you're experiencing this code, it's essential to address it promptly to ensure your vehicle's safety and performance.

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

Symptoms

Common symptoms when C0241 is present:

  • The ABS warning light stays illuminated on the dashboard, indicating a malfunction in the system.
  • You may experience unusual brake behavior, such as pulsing or grabbing, especially during hard braking.
  • Drivers often note a reduction in overall braking performance, which can feel like the brakes are less responsive.
  • Increased stopping distances may occur, especially in wet or slippery conditions, posing a safety risk.
  • In some cases, a related symptom could be the traction control system disabling, leading to loss of vehicle stability.
