Seen this on a manufacturer flow chart. Does anyone know of a ltft post cat data pid. Some vehicles take into consideration rear 02 sensors. This flow chart on a p2096. Can be anything from exhaust leak to lean or rich condition. Code says low limit but says lean or rich conditions can trigger this code. Anyone know anything about this? Is there such a data pid for rear 02 ltft? Ty.
Some will have downstream fuel trim PIDs, some won't. :silly: GM doesn't. You find out that you hit the rich/lean limit when the code sets. Nissan has its A/F ADJ PID. Ford has an actual Rear O2 Fuel Trim PID.
