I've seen conflicting statemens which is why need to ask. How many O2 Sensors are on a 1990 4WD Toyota Pickup, 4 cyl., that isn't in/from California. The manuals at Autozone mention only one but when you search for O2 Sensors at Autozone they prompt you for a front or rear, even if it's only Feneral Emissions and not CA emissions. Please Help!
