TuningBot DTC Database · v4.37.15
7 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the HO2S Bank 1 Sensor 3 Lean System or Low Voltage 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 a fault associated with the Fuel Rail Pressure Malfunction Positive Pressure Deviation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Dodge.
JaguarThe control module judged the Air Assisted Injector Control Valve behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Jaguar.
JeepThe control module detected a fault associated with the Fuel Rail Pressure Malfunction Positive Pressure Deviation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jeep.
NissanThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 1, bank 1 - lean shift 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 Load calculation value was above the expected limit. This is the manufacturer-specific definition used by Audi.
The control module detected that the monitored Load Calculation Cross Check: 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 17551. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (7 interpretations). The control module detected a fault associated with the HO2S Bank 1 Sensor 3 Lean System or Low Voltage 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.
P1143 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Dodge, Jaguar, Jeep, 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. 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.
