What vehicles are most commonly affected by C07E3?

DTC C07E3 is commonly found in vehicles like the 2016-2020 Chevrolet Malibu, 2017-2021 GMC Acadia, and 2015-2020 Buick Enclave, among others.

How can I prevent C07E3 from happening again?

Regular maintenance, including checking wiring and connections, keeping the steering system clean, and ensuring software updates are done, can help prevent C07E3 from reoccurring.

What is C07E3?

DTC C07E3 is a diagnostic trouble code that indicates a fault in the Steering Angle Sensor (SAS) or related systems. This code typically appears in vehicles equipped with advanced driver-assistance systems (ADAS), which utilize the steering angle sensor to help with features like electronic stability control and lane departure warnings. When the C07E3 code is triggered, it can mean that the vehicle's steering angle data is not being processed correctly, which may affect the performance of these safety features. For instance, if you're driving a 2016-2020 Chevrolet Malibu, the C07E3 code might lead to warning lights on your dashboard, including the check engine light, and could potentially compromise your vehicle's handling and stability. Ignoring this code can lead to issues such as decreased fuel efficiency, uneven tire wear, and in severe cases, a loss of steering control. Therefore, it's crucial to address the C07E3 code promptly to ensure both your safety and the longevity of your vehicle.

Symptoms

Common symptoms when C07E3 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the steering angle sensor.
  • Steering feels unresponsive or overly sensitive, leading to difficulty in maintaining control while driving.
  • Vehicle experiences erratic stability control activation, such as the traction control light flashing during normal driving conditions.
  • Increased tire wear, particularly on the front tires, which can be a sign of improper wheel alignment linked to the SAS.
  • Reduced fuel economy, potentially decreasing by 10-15% due to the vehicle's systems compensating for the faulty sensor.

Possible Causes

Most common causes of C07E3 (ordered by frequency):

  1. Faulty Steering Angle Sensor - 60% likelihood. This is the most common cause, often due to wear and tear or electrical issues.
  2. Wiring Issues - 25% likelihood. Damaged or corroded wiring connected to the SAS can disrupt signal transmission.
  3. Calibration Problems - 10% likelihood. The SAS may require recalibration after repairs or battery disconnection to function correctly.
  4. Faulty Electronic Control Unit (ECU) - 4% likelihood. In rare cases, the ECU that interprets the SAS signal may malfunction.
  5. Software Glitches - 1% likelihood. Occasionally, software updates or bugs can cause the SAS to send incorrect signals.
