Q: What does code P2DE7 mean?

Cold Start Engine Coolant Bypass Valve C Range/Performance. P2DE7 indicates that the powertrain control module (PCM) has detected an out-of-range or performance fault in the cold start engine coolant bypass valve circuit, specifically on the 'C' control circuit. The PCM monitors the valve's electrical response and its effect on coolant flow during cold-start warm-up, and it sets this code when the circuit's behavior falls outside the expected range for the commanded position.
