TuningBot DTC Database · v4.37.15
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
BMWThe control module detected that the Mass air flow (MAF)/vane air flow (VAF) - flow value was above the expected limit. This is the manufacturer-specific definition used by BMW.
ChryslerThe control module detected that the Radiator Temp Sensor Input value was above the expected limit. This is the manufacturer-specific definition used by Chrysler.
FordThe control module detected a fault associated with the Pump Rotor Control Underfueling 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.
JeepThe control module detected that the Radiator Temperature Sensor Voltage value was above the expected limit. This is the manufacturer-specific definition used by Jeep.
MINIThe control module detected a fault associated with the Differential Pressure Sensor Intake Manifold Signal circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
PSAThe control module detected that the Fuel flow regulation electrovalve was below its expected limit. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAGThe control module detected improper operation of the Heated oxygen sensor (HO2S) 2, Bank 1, heater circuit. This is the manufacturer-specific definition used by Audi.
The control module detected improper operation of the Heated oxygen sensor (HO2S) heater circuit. 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 (8 interpretations). The control module detected that the Mass air flow (MAF)/vane air flow (VAF) - flow value was above the expected limit. This is the manufacturer-specific definition used by BMW.
P1198 is a manufacturer-specific code. In this database it is documented for: BMW, Chrysler, Ford, Jeep, MINI, PSA, 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.
