2017 Pilot threw P2096 post-cat bank 1 emissions lean code and I'm attempting to determine if the oxygen sensor is bad or something else. I was surprised to see that the O2 sensor is inaccessible without major disassembly of the exhaust system, so I can't run a simple voltage test with no access to the harness. I was hoping to not take it in and pay through the nose for labor to replace the sensor. Can anybody weigh in on this if you've had a similar issue?
