P1161 Diagnostic Trouble Code (10 interpretations)

The control module detected a fault associated with the HO2S Heater Control Circuit Bank 2 Sensor 2 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.

The control module detected a fault associated with the HO2S Heater Power Stage Circuit Bank 2 Sensor 2 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.

The control module detected improper operation of the Heated oxygen sensor (HO2S), too rich, bank 1 circuit. This is the manufacturer-specific definition used by Land Rover.

The control module detected a fault associated with the Fuel Trim Additive Bank 2 High circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.

The control module detected that the EGR throttle position copy signal is jammed or locked. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected a short circuit to ground in the Throttle position regulation fault circuit. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected a short circuit to ground in the Throttle position regulation fault circuit. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the Butterfly position check was not coherent with related operating data. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

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

The control module detected an open circuit or short circuit condition in the Manifold Temp Sensor (G72) circuit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17569. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
