Description of DTC code P2192

The P2192 OBD2 fault code is related to the value delivered by the Oxygen sensor (O2). This sensor helps the car's computer control the amount of fuel that is injected into the engine. The code is set for bank 1, which is at the side of the engine where cylinder 1 is located.

If this code is set, it means that there is a rich condition in the exhaust, during high load conditions. These high load conditions are when the vehicle is driven uphill or when accelerating rapidly.

Symptoms of fault code P2192

  • Check Engine light illumination.
  • Noticeable lack of power.
  • Intermittent misfires.
  • Increased fuel consumption.
  • Poor acceleration.
  • Hesitation or misfiring on acceleration.
  • Black smoke out of the exhaust pipe.

Causes of OBD2 P2192

The reasons for the DTC P2192 OBDII code being set are:

  • The Oxygen Sensor (O2) is possibly faulty.
  • The Mass Air Flow (MAF) sensor may be damaged.
  • PCM error.

Possible solutions of the DTC code P2192

The steps for the proper repair of the P2192 OBD2 diagnostic code are:

  • It is recommended as the first step for a correct diagnosis, to consult the Technical Service Bulletins (TSB). The information contained in them will be very useful.
  • If there are other trouble codes they should be repaired first, especially if they are fuel system codes.
  • Inspect the Air Mass Flow Sensor and Oxygen Sensor, and check their wires and connectors for good condition. Repair burned or frayed wires.
  • Test the voltage signal sent by the MAF sensor to the PCM. To do this, use a scanner with which you can check the voltage of the Mass Air Flow Sensor. If you do not have a scanner, use a DVOM and take voltage readings. Compare with the manufacturer's specifications and if you find inconsistencies, replace the MAF sensor.
  • Perform a test of the O2 sensor. The O2 sensor voltage should change rapidly between 0.1 to 0.9 volts. If not, proceed to replace the Oxygen Sensor.
