TuningBot DTC Database · v4.37.14
12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the HO2S Lean Average Bank 2 Sensor 1 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.
DodgeThe control module detected that the Fuel Rail Pressure Malfunction Rail Pressure Is value was above the expected limit. This is the manufacturer-specific definition used by Dodge.
FordThe control module detected a fault associated with the Alternative Fuel Controller 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.
HyundaiThe control module detected improper operation of the Limp Home Valve. This is the manufacturer-specific definition used by Hyundai.
JeepThe control module detected that the Fuel Rail Pressure Malfunction Rail Pressure Is value was above the expected limit. This is the manufacturer-specific definition used by Jeep.
KiaThe control module detected improper operation of the Limp - home solenoid. This is the manufacturer-specific definition used by Kia.
MINIThe control module detected an unstable or intermittent signal in the O2 Sensor Heater circuit. This is the manufacturer-specific definition used by MINI.
NissanThe control module detected improper operation of the Turbocharger (TC) wastegate regulating valve - RH circuit. This is the manufacturer-specific definition used by Nissan.
PSAThe stored code identifies a fault of the Motorised throttle control. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
SubaruThe control module judged the Heated oxygen sensor (HO2S) 1, bank 2 behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Subaru.
VAGThe control module detected a short circuit to battery voltage in the Manifold absolute pressure (MAP) circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to battery voltage in the Manifold Abs.Pressure Sensor (G71): Circ. circuit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17563. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (12 interpretations). The control module detected a fault associated with the HO2S Lean Average Bank 2 Sensor 1 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.
P1155 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Dodge, Ford, Hyundai, Jeep, Kia, MINI, Nissan, PSA, Subaru, 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.
