Common Questions

What does C0170 mean and how does it affect my car?

The C0170 code indicates a problem with your vehicle's wheel speed sensor. This sensor is critical for the proper functioning of anti-lock brakes and traction control. If it's malfunctioning, you may experience issues like inconsistent braking and a loss of control during slippery conditions, which can be dangerous.

What are the most common causes of C0170 and how much does it cost to fix?

The most common cause of C0170 is a faulty wheel speed sensor, which can be replaced for $100 to $300. Other causes include damaged wiring, which can be repaired for $50 to $150, and less frequently, a faulty ABS control module, which may cost $200 to $600 to replace.

Can I drive my car with C0170 or should I stop immediately?

While you may be able to drive your vehicle, it is not advisable to ignore the C0170 code. The malfunction could impact your brakes and traction control, making driving hazardous, especially in adverse conditions. It's best to have it diagnosed and repaired as soon as possible.

How can I diagnose C0170 myself using GeekOBD APP?

To diagnose C0170 with the GeekOBD APP, connect it to your vehicle’s OBD2 port. Run a scan to retrieve the trouble codes, then review the freeze frame data to see the conditions when the fault occurred. Check the live sensor data to see if the wheel speed readings are consistent across all wheels.

What vehicles are most commonly affected by C0170?

C0170 is frequently encountered in 2000-2015 Chevrolet Silverado, GMC Sierra, and other General Motors models equipped with similar ABS systems. It's important to check for any recalls or technical service bulletins related to these issues.

How can I prevent C0170 from happening again?

To prevent the C0170 code from recurring, regularly inspect your vehicle's wiring and connectors for signs of wear or damage. Additionally, ensure that your vehicle's ABS system is serviced according to the manufacturer’s recommendations, and keep an eye on the performance of your brakes and tires.

What is C0170?

The DTC C0170 code indicates a malfunction within the wheel speed sensor circuit, which is crucial for functions such as anti-lock braking systems (ABS) and traction control. When the vehicle's onboard diagnostics system detects an issue with this sensor, it triggers the C0170 code, signaling that the wheel speed information being relayed to the vehicle’s control module is incorrect or unreliable. This code is commonly seen in vehicles like the 2000-2015 Chevrolet Silverado, GMC Sierra, and other GM models that utilize similar ABS systems. The implications of ignoring this code can be significant, as a malfunctioning wheel speed sensor can lead to reduced braking efficiency, uneven tire wear, and compromised vehicle stability during slippery conditions. In many cases, a failing wheel speed sensor can cause the ABS warning light to illuminate on the dashboard. Additionally, without accurate wheel speed data, the traction control system may not function correctly, potentially leading to dangerous driving conditions, especially in wet or icy weather. It’s recommended that any vehicle showing this code be diagnosed promptly to ensure safe operation.

Symptoms

Common symptoms when C0170 is present:

  • Check engine light illuminates and remains on, indicating a fault in the ABS or traction control system.
  • ABS warning light activates, which may affect braking performance and overall vehicle safety.
  • Inconsistent braking performance, with possible skidding or loss of control during emergency stops.
  • Decreased fuel economy due to the vehicle's traction control system engaging more frequently.
  • Tire wear patterns may become uneven, leading to the need for more frequent tire replacements.

Possible Causes

Most common causes of C0170 (ordered by frequency):

  1. Faulty wheel speed sensor - 60% likelihood. This is the most common cause, often due to wear and tear or exposure to road debris.
  2. Damaged wiring or connectors in the wheel speed sensor circuit - 25%. Corrosion or physical damage can disrupt the signal.
  3. Faulty ABS control module - 10%. If the module fails, it might misinterpret the signals from the wheel speed sensor.
  4. Software issues within the vehicle's control module - 4%. Rare, but can occur if there are updates or glitches.
  5. Electrical issues with the vehicle's battery or alternator - 1%. A weak electrical system can affect sensor performance.
