Description of DTC code P2096

The Powertrain Control Module (PCM) controls the amount of oxygen present in the engine exhaust. The lower the oxygen content, the richer the air/fuel mixture, and the opposite occurs when the oxygen content is higher. This process is monitored by the Powertrain Control Module (PCM) through Oxygen (O2) Sensors, which send reference signals to determine the amount of oxygen.

When the PCM detects that the fuel system's ranges are excessively rich, the DTC code P2096 OBDII will be set and the Check Engine service light will be illuminated.

Symptoms of fault code P2096

  • Fault Indicator Lamp (MIL) on.
  • Low fuel economy.
  • General engine problems.
  • Excessively high temperature in the catalytic converter (TWC).

Causes of OBD2 P2096

The reasons for storing the diagnostic code P2096 OBD2 are

  • Possibly the Catalytic Converter (TWC) is malfunctioning.
  • The MAF (Mass Air Flow) Sensor may be damaged.
  • The electrical circuit of the fuel compensation system may be short due to damage to its wires.
  • The fuel pump may be blocked.

Possible solutions of the DTC code P2096

Take the following steps to correct the fault code P2096 OBDII:

  • Verify that the cable harness and connectors associated with the system are in good condition. If you notice that the wires running near the exhaust are damaged or worn, you should make the necessary repairs or changes.
  • By using a DVOM, perform voltage and ground tests on the O2 Sensor. If the reading is different from the specified by the manufacturer, check on the electrical connections. Make repairs as required and replace the Oxygen Sensor if necessary.
  • Check the fuel pump and filter for blockages. If some elements are blocking their operation, perform proper maintenance.
  • Check that the components of the Mass Airflow Sensor circuit are not damaged. If you find any open or shorted circuits, take the necessary measures.
