TuningBot DTC Database · v4.37.14
7 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected that the Fuel Injection Pump Battery Voltage value was outside the valid range. This is the manufacturer-specific definition used by Chrysler.
DodgeThe control module detected that the Fuel Injection Pump Battery Voltage value was outside the valid range. This is the manufacturer-specific definition used by Dodge.
HyundaiThe control module detected a fault associated with the Direction Potentiometer Short (High) - Auto Defog circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.
JeepThe control module detected that the Fuel Injection Pump Battery Voltage value was outside the valid range. This is the manufacturer-specific definition used by Jeep.
MINIThe control module detected that the Switching Solenoid for Air Assisted Injection Valves Bank 1 Control signal stayed below the expected range. This is the manufacturer-specific definition used by MINI.
NissanThe control module detected a fault associated with the Heated oxygen sensor (HO2S), bank 2 - rich mixture 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 an interruption (open circuit) in the Fuel Injection Air Control Valve circuit, so the expected electrical continuity was not present. 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 that the Fuel Injection Pump Battery Voltage value was outside the valid range. This is the manufacturer-specific definition used by Chrysler.
P1284 is a manufacturer-specific code. In this database it is documented for: Chrysler, Dodge, Hyundai, Jeep, MINI, 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 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.
