1996 Ford Ranger 4 cyl Two Wheel Drive Manual 155000 miles
Had to replace O2 sensor and reset the computer, I then drove it for two days, on and off the freeway without getting a check engine light. So I went to get a smog check and it failed do to the computer not completing it's diagnostic testing. How do you have to drive it so the computer will perform their diagnostic testing so all the monitors get checked. I ran it through my INNOVA 3100 OBD2 code reader when I got home and it shows catalyst monitor, oxygen sensor monitor, oxygen sensor heater monitor, haven't ran yet. What can I do to get it to reset so it will smog. Michael L. Worstman
