Code C1AA3 2013 Toyota RAV4 Description

The C1AA3 diagnostic trouble code (DTC) in a 2013 Toyota RAV4 indicates a problem with the vehicle speed sensor circuit. The vehicle speed sensor (VSS) is a crucial component that monitors the speed of the vehicle and sends this information to the engine control module (ECM) to assist in various functions such as fuel injection, transmission shifting, and ABS operation. When the ECM detects an issue with the VSS circuit, it triggers the C1AA3 code.

Tech Notes for C1AA3 2013 Toyota RAV4

When replacing the Forward Recognition Camera, always replace it with a new one. If a Forward Recognition Camera which was installed in another vehicle is used, the information stored in the Forward Recognition Camera will not match the information from the vehicle. As a result, a DTC may be stored.

If the Forward Recognition Camera has been replaced with a new one, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.
