Does anyone know if clearing the DTC's also resets the monitors back to where I have to perform the drive cycle all over again? It wont pass smog now with the P1000 and P0541. I've performed the Ford drive cycle several times and cannot get rid of the two codes. I befieve the p0541 is a soft code. I keep clearing the codes but of course they come back so I don't know if I'm clasing my tail by clearing them or not.
