What does code P26C7 mean?

Q: What does code P26C7 mean?

Exhaust Flow Control Valve A Control Circuit High. P26C7 is a generic powertrain code indicating that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for Exhaust Flow Control Valve A. The PCM commands the valve to a specific position and monitors the circuit; a high voltage reading, typically near battery voltage when the valve is commanded off or at a level outside the expected range, triggers this code.
