What Does P0467 Mean? The P0647 code is a generic OBD-II trouble code that detects a problem with the A/C (air conditioning) clutch relay control circuit. The A/C clutch relay control circuit sends information to the powertrain control module (PCM), and many other control modules, such as the anti-lock brake control module, traction control module, climate control module, and instrument panel control module. When the PCM or one of the other control modules identifies that the A/C clutch relay control circuit is malfunctioning, the P0647 code will be triggered. engine code P0467P0467 fixobd P0467dtc P0467obd code P0467obd2 P0467P0467 car codediagnostic code P0467car code P0467check engine code P0467fehlercode P0467P0467 fiatcodigo P0467codigo falla P0467P0467 kody b??dówcodigo de falla P0467 What are the common causes of P0467 ?
