2001 Chevrolet Prizm Parts Questions & Experts Answers

• Q: How to replace the Heated Oxygen Sensor (HO2S) 2 on 2001 Chevrolet Prizm?

  A: Engine temperature must be below 48 when changing the heated Oxygen Sensor (HO2S) 2 because removal becomes difficult at and beyond 120 °f. The first step requires removal of the front floor console and subsequent passenger carpet removal from the console floor region. Start by disconnecting the ho2s 2 electrical connector then extract the wiring from its position under the floor heat duct. Lower the vehicle automatically and position it on a hoist. Then disconnect the wiring and body plug from the Floor Pan. Remove the ho2s 2 from the Exhaust Pipe by following steps which safeguard the threaded section from damage. The new ho2s 2 arrives with pre-applied anti-seize coating so discard the safety instructions regarding its removal before installing. Fasten the ho2s 2 into place on the Exhaust Pipe using 44 n.m torque pressure (32 lb ft). Reattach the wiring and body plug to the Floor Pan while lowering the vehicle before running the ho2s wires under the heater floor duct to complete the connection of the ho2s 2 electrical connector . Last step involves putting back the carpet covering which spans the console area and front floor console.
