Jeep Code P0223 is a diagnostic trouble code (DTC) that is stored when the electronic throttle control system has detected an abnormally high voltage on the throttle position sensor 2 circuit. This code is triggered when the Powertrain Control Module (PCM) receives a signal voltage that is higher than what is expected during normal operation. This code can cause a wide range of issues, from a faulty throttle position sensor, to a short in the 5-volt supply circuit, or an open/high resistance in the signal circuit. In order to properly diagnose and fix the issue, it is essential to understand the underlying causes of P0223 and the solutions to rectify it.
