• Q: How to replace the Heated Oxygen Sensor (HO2S) 2 using the J 39194-B Heated Oxygen Sensor Wrench on 2005 Chevrolet Venture?

  A: Use J 39194-B heated oxygen sensor wrench (J 39194-B) when replacing heated oxygen sensor (ho2s) 2 but keep the pigtail connected to prevent sensor operation failure. Handle the oxygen sensor gently while keeping the in-line electrical connector and louvered end clean from grease and dirt and contaminants. Clean all components by using only specified cleaning solutions then check if the oxygen sensor pigtail or connector or terminal needs cheaper replacement over small repairs. Any repairs to wires connectors or terminals which affect air reference performance should be avoided to preserve the sensor's functionality. Service procedures should include avoiding contact cleaner application on both sensors and vehicle harness connectors and keeping sensor pigtail wires and harness wires free from exposure to contaminants while ensuring all lead wires remain straight and free from kinks. Leave the oxygen sensor ground wire attached when possible because proper sensor functionality relies on its presence. The peripheral seal of the vehicle harness connector must be free of damage to safeguard water penetration points; repairs should utilize Packard's crimp and splice seals terminal repair kit instead of soldering methods. Turn off the ignition system followed by vehicle elevation to access the heated oxygen sensor for disconnection then connector removal using J 39194-B. For installation, coat the threads of the heated oxygen sensor with anti-seize compound gm p/n #5613695 or an equivalent, as this special compound aids in future removals. Place the ho2s2 sensor and torque it to 41 N.m (30 lb ft) before connecting the electrical connector and letting the vehicle down.
