• Q: How to replace the Heated Oxygen Sensor (HO2S) 1 on 2004 Chevrolet Venture?

  A: The replacement of Heated Oxygen Sensor (HO2S) 1 requires the use of J 39194-B Heated Oxygen Sensor Wrench (J 39194-B). Among handling steps for the oxygen sensor you should maintain gentle treatment to prevent drops and preserve an uncluttered state for electrical connections and the louvered end. Both the HO2S and O2S should maintain their pigtail attached during any operation because removing them would cause damage to the sensors. Replace the oxygen sensor altogether when you identify wiring or connector or terminal damage in the pigtail system because any fixes at this stage will not succeed. Keep the sensor and all lead wires straight while also protecting both sensor connectors from contact cleaners and vehicle connector materials. Follow this procedure to remove heated oxygen sensors: stop the ignition then lift the vehicle and unplug the electrical connector before gently using the J 39194-B to extract the heated oxygen sensor. Before sensor installation use GM P/N 5613695 anti-seize compound (or equivalent brand) on the heated oxygen sensor/catalyst monitor thread. Next install the HO2S 1 (pre-catalytic converter) at 41 N.m (30 lb ft) torque while you connect its sensor electrical connector and bring down the vehicle.
