POST UPDATED IN May, 2021
Description of DTC code P2098 Generic
The O2 sensors indicate the PCM the amount of oxygen that is in the exhaust, which is used to control and determine the air/fuel mixture. If there is a high oxygen content, the mixture is lean. Contrary to this, a rich mixture will be obtained. The Oxygen Sensor has a cycle every second. It provides the PCM with a voltage that varies between 0.2 to 0.8 for a lean or rich mixture respectively.
The DTC P2098 OBDII indicates that the Powertrain Control Module (PCM) detects through the Oxygen (O2) Sensors, a lean condition in the fuel trim system, which is located at the rear of the Catalytic Converter (TWC).
