Meanwhile, the PCM uses data from the downstream O2 sensor (the one after the converter) to determine converter ...
How To Diagnose High Negative Long Term Fuel Trim - Garatos
The downstream sensor should stay relatively similar to the upstream sensor. If it does not, then the catalytic converter has a problem. If all is functioning properly, the long-term fuel trim is balanced and adjusted correctly. Short-term fuel trim happens with the oxygen in the exhaust changes. This trim is monitored by the upstream exhaust ...
