What is the p2098 OBD-II trouble code?
P2098 is an OBD-II generic code for the engine control module (ECM) detecting the post catalyst O2 sensor fuel trim is testing too lean on a two trip minimum to set the code. What causes the P2098 code?
What does p2098 post catalyst fuel trim system too lean mean?
P2098 Post Catalyst Fuel Trim System Too Lean Bank 2 1 OBD-II Trouble Code Technical Description. What does that mean? 2 Symptoms. The symptoms of a P2098 code will vary depending on the component or system causing the disruption in the fuel trim. 3 Potential Causes. 4 Diagnostic and Repair Procedures. 5 Related DTC Discussions. …
What are the symptoms of a p2098 DTC set?
The symptoms of a P2098 code will vary depending on the component or system causing the disruption in the fuel trim. Not all will be present simultaneously. Malfunction Indicator Lamp (MIL) illumination with P2098 DTC set. Rough idle. Poor fuel economy. Poor acceleration. Misfire. Cherry red hot catalytic converter.
Why is my post catalyst O2 sensor not working?
The ECM is detecting the pre catalyst O2 sensor not working correctly and then monitors the post catalyst O2 sensor to see if the problem correlates to the pre catalyst O2 sensor on a two trip requirement. The exhaust may have a leak or engine problem before the pre catalyst sensor.

When to replace O2 sensors in post catalyst?
Replace O2 sensors for the pre and post catalyst if they are damaged from an issue that has got repaired like a head gasket that leaked coolant into the exhaust Code P2098 will come on only after the ECM has detected the problem to happen for two complete drive cycles.
What does the PCM error code p2098 mean?
Error Code P2098 means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) has determined that the signal voltage input coming from the downstream (post catalytic) O2 (oxygen) converter sensor has indicated that the O2 particle content is too high.

What is the post catalyst O2 sensor p2098?
Code P2098 involves the post catalyst oxygen sensor on bank 2. The post catalyst O2 sensor is the one downstream from the catalytic converter, which is usually referred to as sensor #2. This article outlines the generic code definition from the Society of Automotive Engineers (SAE).
What is the target fuel / air ratio for p2098 Bank 2?
In operation the oxygen sensor will cycle once every second and send a voltage to the computer that ranges from 0.2 rich to 0.8 for a rich mixture. The perfect mixture will average the signals around 0.45 volts. The computer’s target fuel/air ratio is 14.7:1.
