What does code P26C6 mean?

Q: What does code P26C6 mean?

Exhaust Flow Control Valve A Control Circuit Low. P26C6 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for Exhaust Flow Control Valve A, which is used to manage exhaust gas flow for purposes such as noise reduction or thermal management. The PCM commands the valve to a certain position but sees the circuit voltage stay below the expected threshold, indicating a short to ground, an open circuit, or a faulty valve actuator.
