TuningBot DTC Database · v4.37.15
11 manufacturer-specific interpretations across 9 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Cylinder Select circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
JaguarThe control module detected a fault associated with the Engine control module (ECM) circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jaguar.
ECM
Land RoverThe control module detected a fault associated with the Engine control module (ECM) - coding circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
Incorrectly coded
Mercedes-BenzThe control module detected a fault associated with the Electrohydraulic Shut - Off Actuator Y11 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mercedes-Benz.
OpelThe control module detected a fault associated with the Fuel pump relay circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Opel.
PSAThe stored code identifies a fault of the ECU internal fault. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The stored code identifies a fault of the ECU internal fault. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The control module detected the fault condition "Safety" for the Incoherence between the various butterfly angle and intake pressure information. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
SuzukiThe control module registered the fault condition described as "Engine control module (ECM) - EEPROM error". This is the manufacturer-specific definition used by Suzuki.
ECM
VAGThe control module judged the Instrument panel, ECT signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Audi.
VolvoThe control module detected improper operation of the Knock control. This is the manufacturer-specific definition used by Volvo.
ECM
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (11 interpretations). The control module detected a fault associated with the Cylinder Select circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
P1622 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Jaguar, Land Rover, Mercedes-Benz, Opel, PSA, Suzuki, VAG, Volvo. 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.
