Need O2 sensor advice 850 94

posted by  someone claiming to be Joe on  Tue Oct 30 06:44 CST 2001 [RELATED]

My 94 850 Turbo Wagon recently posted codes 435 and 443, which refer to the front O2 sensor and the cat (can't remember which is which). I'll check about vacuum tubing leaks (possible reason for setting codes), but with 110,000 miles on the original sensors, I'm inclined to replace them any way. My questions are:

1. Has anyone gone the universal sensor route, and if so, where did you get it?

2. Shoud I replace the rear sensor as well? Has anyone relaced the rear O2 sensor, and if so where did you get it (except for Volvo)?

3. If the cat code doesn't go away when the O2 sensor is replaced, how do I test the cat?
