When is the Code Detected?

The P1147 code is triggered when the sensor’s maximum voltage is not reached at the specified voltage.

Possible Symptoms

  • Check engine light on (or engine warning light about to activate)
  • Possible high fuel consumption
  • Possible excessive smoke from exhaust gases

P1147 NISSAN Meaning

The Heated Oxygen Sensor 2 (HO2S) (rear O2 sensor), located after the three-way catalyst (manifold), monitors the oxygen level in the exhaust gases in each bank. For optimal catalyst operation, the air-fuel mixture (air-fuel ratio) must be maintained near the ideal stoichiometric ratio. The HO2S output voltage changes abruptly near the stoichiometric ratio. The Engine Control Module (ECM) adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. The HO2S generates a voltage between 0.1 and 0.9 V in response to the oxygen in the exhaust gases. If the oxygen in the exhaust gases increases, the air-fuel ratio becomes lean. The ECM interprets a lean mixture when the HO2S voltage is below 0.45 V. If the oxygen in the exhaust gases decreases, the air-fuel ratio becomes rich. The ECM interprets a rich mixture when the HO2S voltage is above 0.45 V.

P113C Chrysler Meaning

The oxygen sensor is controlled by the intelligent oxygen module (Smart O2 Module). This module is an intelligent device that receives information from the main engine electronic control module (ECM), such as dew point indicator, engine speed, etc. It provides oxygen concentration signals to the ECM. Simultaneously performs self-diagnostic functions and reports faults to the main engine ECM. The ECM then decodes the error information and converts it into a trouble code.
