• Q: How to Replace a Heated Oxygen Sensor (HO2S) 2 on 2002 Chevrolet Prizm?

  A: Replacement of the heated Oxygen Sensor (HO2S) 2 requires a cool engine because temperatures above 48°c (120°F) create difficulties during removal. Start by taking off floor console in front then reach behind passenger side carpet to expose the console floor area. Unplug the electrical connector of ho2s 2 before you detach its wiring beneath the floor heat duct. Raise the vehicle while properly supporting it and eliminate the wiring and the floor pan body plug. Proceed to take the ho2s 2 sensor out of the Exhaust Pipe. When installing the sensor users must retain the original anti-seize coating on the new device. Tighten the ho2s 2 Exhaust Pipe installation to 44 n.m (32 lb ft). Start by placing the wiring and body plug back inside the floor pan and lowering the vehicle before passing the ho2s wiring beneath the heater floor duct for final connector installation. Reposition the passenger side carpet across the console area and front floor console.
