P1158 Diagnostic Trouble Code (11 interpretations)

The control module detected a fault associated with the Fuel Trim Adaptation Additive Bank 1 Low circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.

The control module detected a fault associated with the HO2S Bank 2 Sensor 2 Rich Or High 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.

The control module detected a fault associated with the Lack of O2 Switches Bank 2 Sensor 2 Indicates Lean 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.

The control module detected that the signal in the Heated oxygen sensor (HO2S) - front circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Honda.

The control module detected a fault associated with the Heated oxygen sensor (HO2S) 2 - cylinders 4,5, 6 - mixture rich circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.

The control module detected a fault associated with the Heated oxygen sensor (HO2S) 2, bank 2 - rich mixture indicated circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.

The control module detected a fault associated with the Engine Compartment Temperature circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.

The control module detected a short circuit to battery voltage in the Motor-driven throttle unit, signal 2 circuit. 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 judged the Manifold absolute pressure (MAP) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Audi.

The control module judged the Manifold Pressure Sensor (G71) signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17566. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

The control module detected a fault associated with the Heated oxygen sensor (HO2S) 2, bank 2 - rich circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volvo.
