TuningBot DTC Database · v4.37.14
4 manufacturer-specific interpretations across 3 manufacturers in the TuningBot DTC database.
Mercedes-BenzThe control module detected improper operation of the Engine coolant temperature (ECT) sensor(s). This is the manufacturer-specific definition used by Mercedes-Benz.
NissanThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 2, bank 1 - maximum voltage monitoring circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Nissan.
VAGThe control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Heated oxygen sensor (HO2S) 1, Bank 2 - lambda regulation, system). This is the manufacturer-specific definition used by Audi.
The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Heated oxygen sensor lambda regulation, system). 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 (4 interpretations). The control module detected improper operation of the Engine coolant temperature (ECT) sensor(s). This is the manufacturer-specific definition used by Mercedes-Benz.
P1147 is a manufacturer-specific code. In this database it is documented for: Mercedes-Benz, Nissan, 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 and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
