TuningBot DTC Database · v4.37.15
Generic (OBD-II) interpretation + 1 manufacturer-specific in the TuningBot DTC database.
FordThe control module detected an interruption (open circuit) in the Exhaust Flow Control Valve A Control circuit, so the expected electrical continuity was not present.
FordFord documents P26C5:11 (circuit short to ground) for its 2024-2025 gasoline-engine OBD monitor strategy as exhaust flow control valve “a” control circuit low. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Ford documents P26C5:12 (circuit short to battery) for its 2024-2025 gasoline-engine OBD monitor strategy as exhaust flow control valve “a” control circuit high. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Ford documents P26C5:13 (circuit open) for its 2024-2025 gasoline-engine OBD monitor strategy as exhaust flow control valve “a” control circuit/open. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Powertrain: engine, transmission and driveline systems.
Generic SAE-standard code: same meaning on every make.
Specific fault index within the subsystem.
Diagnostic Trouble Code (3 variants). The control module detected an interruption (open circuit) in the Exhaust Flow Control Valve A Control circuit, so the expected electrical continuity was not present.
P26C5 exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
