TuningBot DTC Database · v4.37.14
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected improper operation of the Brake pedal position (BPP) switch. This is the manufacturer-specific definition used by Alfa Romeo.
ChevroletThe control module detected a fault associated with the Electronic Variable Orifice Output 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.
ChryslerThe control module detected a fault associated with the Electronic Variable Orifice Output circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
HondaThe control module detected that the signal in the Hybrid battery pack temperature sensor 2 circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Honda.
LexusThe control module detected that the signal in the Reactor Temperature circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Lexus.
OpelThe control module judged the Throttle position (TP) sensor A / mass air flow (MAF) signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Opel.
PorscheThe control module detected a fault associated with the Charge Pressure Characteristics circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
ToyotaThe control module detected that the signal in the Reactor Temperature circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected that the monitored Turbocharger (TC) pressure - upper limit value exceeded the calibrated threshold. This is the manufacturer-specific definition used by Audi.
The control module detected that the monitored Boost Pressure Control: Upper Limit value exceeded the calibrated threshold. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17963. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
VolvoThe control module detected improper operation of the Engine control relay. This is the manufacturer-specific definition used by Volvo.
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 improper operation of the Brake pedal position (BPP) switch. This is the manufacturer-specific definition used by Alfa Romeo.
P1555 is a manufacturer-specific code. In this database it is documented for: Alfa Romeo, Chevrolet, Chrysler, Honda, Lexus, Opel, Porsche, Toyota, 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 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.
