To learn more about catalysts on today’s vehicles and how they can trigger OBD-II codes like p2098, read our explanation here.ĭuring the course of watching the upstream O2 sensor, the ECM/PCM also watches the downstream sensor for indications that the mixture is too lean – and if the upstream O2 sensor on that bank becomes unreliable, the ECM/PCM will actually begin to adjust fuel trims based on rear O2 sensor input. The O2 sensor behind the catalyst monitors O2 storage capacity that being said, the ECM/PCM factors in readings of both the front and rear (upstream and downstream) sensors to determine proper exhaust stream composition. This is the only catalyst that is monitored by the ECM/PCM. The catalyst brick nearest the engine takes care of NOx emissions and is referred to as the “light-off cat.” This catalyst has to reach a certain temperature to begin the catalytic process of separating NOx into its nitrogen and oxygen components. This code points to a too-lean reading from the downstream sensor. ” It means the exhaust stream on the bank 2 side contains higher oxygen levels exiting the converter than it should. What Does the P2098 Code Mean?ĭiagnostic trouble code (DTC) stands for “P2098 Post Catalyst Fuel Trim System Too Lean (Bank 2).
The catalytic converter helps control your car’s emission levels by breaking down noxious gases into less harmful pollutants before they leave your exhaust. When the bank 2 oxygen sensor 2 unit reports a lean condition in the exhaust stream leaving the converter, the engine’s computer stores a code P2098. Hurry, deals going fast!
