TuningBot DTC Database · v4.37.15
7 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected that the Battery voltage state or value did not match what was expected. This is the manufacturer-specific definition used by Alfa Romeo.
ChevroletThe control module detected an unstable or intermittent signal in the Mass Air Flow circuit. This is the manufacturer-specific definition used by Chevrolet.
ChryslerThe control module detected an unstable or intermittent signal in the Mass Air Flow circuit. This is the manufacturer-specific definition used by Chrysler.
DodgeThe control module judged the Crankshaft position (CKP) sensor/camshaft position (CMP) sensor 2, bank 1 behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Dodge.
FordThe control module detected a fault associated with the Injector Control Pressure Sensor Above / Below Desired circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
VAGThe control module detected an interruption (open circuit) in the Intake Valves For Cylinder Shut Off circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
The control module detected an interruption (open circuit) in the Intake Valves For Cylinder Shut Off circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Volkswagen.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (7 interpretations). The control module detected that the Battery voltage state or value did not match what was expected. This is the manufacturer-specific definition used by Alfa Romeo.
P1211 is a manufacturer-specific code. In this database it is documented for: Alfa Romeo, Chevrolet, Chrysler, Dodge, Ford, VAG. The same number can mean something different on other brands.
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.
