HO2S Bank 2 Sensor 3 Lean System Or Low Voltage Chrysler · emissions Data confidence 62%

The control module detected a fault associated with the HO2S Bank 2 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 Chrysler.

Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Confirm the exact vehicle, ECU and software context
  • Inspect relevant wiring and connectors
  • Check applicable OEM service information

PSA

1 interpretation
P1163
Injectors control : The engine has not encountered the conditions to reset the injector dead times (Rail pressure low) PSA · fuel Data confidence 72%

The control module detected the fault condition "The engine has not encountered the conditions to reset the injector dead times (Rail pressure low)" for the Injectors control. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

Applies to Peugeot Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi)

VAG

2 interpretations
P1163
Fuel temperature sensor - open circuit/short to positive VAG · fuel Data confidence 62%

The control module detected an interruption (open circuit) in the Fuel temperature circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.

Possible causes

  • Wiring open circuit/short to positive
  • fuel temperature sensor
Applies to Audi
P1163
Fuel Temp Sensor (G81): Open or Short to Plus VAG · engine Data confidence 88%

The control module detected a short circuit to battery voltage in the Fuel Temp Sensor (G81): Open or circuit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17571. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
