TuningBot DTC Database · v4.38.5
7 manufacturer-specific interpretations across 5 manufacturers in the TuningBot DTC database.
BMWThe control module detected an interruption (open circuit) in the Heated oxygen sensor (HO2S) 1, bank 1 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by BMW.
DodgeThe control module judged the Heated oxygen sensor (HO2S) 1, bank 1 behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Dodge.
MINIThe control module detected a fault associated with the Valvetronics Actuator Motor Activation 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 the fault condition "Short circuitto earth" for the Fault in the variable valve lift system. 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.
The control module detected the fault condition "Short circuitto earth" for the Fault in the variable valve lift system. 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.
VAGThe control module detected a short circuit to battery voltage in the Camshaft position (CMP) actuator, exhaust/ right/rear, Bank 1 circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to battery voltage in the Camshaft position (CMP) actuator, exhaust 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 (7 interpretations). The control module detected an interruption (open circuit) in the Heated oxygen sensor (HO2S) 1, bank 1 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by BMW.
P1048 is a manufacturer-specific code. In this database it is documented for: BMW, Dodge, 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.
