What is C0A67?

DTC C0A67 is a diagnostic trouble code that indicates an issue with the vehicle's power steering system, specifically relating to the power steering control module. When this code appears, it typically means that the system has detected a malfunction in the communication between the steering wheel and the vehicle's electronic systems. This could be due to various reasons, including faulty wiring, a malfunctioning power steering motor, or issues with the control module itself. For vehicle owners, this can lead to several noticeable symptoms such as difficulty steering, a warning light on the dashboard, or even complete loss of power steering assistance. It is crucial to address this code promptly, as neglecting it can lead to increased wear on other steering components and potential safety hazards while driving. Commonly found in vehicles like the 2016-2020 Toyota RAV4, it's essential for owners to understand that ignoring DTC C0A67 could lead to more costly repairs down the line and may affect overall vehicle performance.
