Tacoma Hybrid cruise control failure

A malfunctioning cruise control system in your 2023 Tacoma Hybrid could stem from a few sources. Given the error code, I'd initially suspect a fault in the electrical circuit. Have you checked the fuse box for any blown fuses related to the cruise control system? Furthermore, the throttle position sensor or speed sensors are crucial for cruise control operation; a defect there could also trigger these symptoms. Any recent work on the vehicle?

Where exactly is the fuse box located, and is there a diagram to check which fuse is for the cruise control? Also, would a bad speed sensor throw a dashboard light?

The fuse box is typically located either under the dashboard or in the engine compartment. Your owner's manual should contain a fuse box diagram indicating the specific fuse for the cruise control system. Moreover, a faulty speed sensor commonly does illuminate the check engine light (malfunction indicator lamp) on the dashboard, and could potentially affect other systems beyond cruise control. Given the defective cable or plug is the likely cause according to the error, professional diagnostics at a workshop would be prudent to pinpoint the exact component before replacing parts.

Thanks. Took it to the shop; it was a loose connection like you said. Cost 95€ to fix. Appreciate the advice!
