Post catalyst fuel trim too lean bank 1. Find out the most popular Mitsubishi fault codes along with what they mean. Learn its causes—exhaust leaks, faulty O2 sensors, fuel system issues—and risks like catalytic converter damage. . This means that the engine is receiving too much air and not enough fuel after the catalytic converter. Given your extensive diagnostic steps, here are a few additional considerations: - MAF Sensor: A faulty or dirty MAF sensor can cause lean conditions. 2 days ago · Jack, P0171 indicates a lean condition on Bank 1. 5 keeps occasionally tossing this code. When I clear it, it'll be off for a few days/week then randomly come back on. The code P2096, post catalyst fuel trim system too lean on bank 1 simply translates to a lean (too much air and not enough fuel) condition the PCM recognized through the signals from the oxygen sensors. However, if the amount of compensation is too much, a P0173 code may set. Often caused by bad O2 readings forcing the car to over-correct the fuel. Essentially, this means that the engine’s computer has detected a deficiency in fuel mix after exhaust gases have passed through the catalytic converter.
