Code P060B Lexus Description

The P060B diagnostic trouble code (DTC) for Lexus vehicles indicates a problem with the internal control module A/D processing performance. The control module, also known as the engine control module (ECM) or powertrain control module (PCM), is responsible for monitoring and controlling various systems within the vehicle, such as engine performance, emissions, and transmission. The A/D processing performance refers to the module's ability to accurately convert analog signals to digital signals for processing and control purposes.
