Trouble codes for left front and left rear tpms sensors.Replaced both sensors with aftermarket (DORMAN) sensors. Proceeded to program sensors using ipc . Horn sounded for each wheel but when driving vehicle ipc does not display a pressure reading for either l/f or l/r wheels. Is it the aftermarket sensors that aren't compatible with the RFA transmitter? Need input . Thanks
