Re: How many o2 sensors?

I am pretty sure there is a front O2 and a rear O2...front of the cat and rear of the cat. Please correct me if I am wrong!

Please post if everything lines up well or if you run in to bolt alignment problems with the universal cat.

Re: How many o2 sensors?

there's a pre cat o2 sensor and a secondary that is actually plugs in the cat itself on obd2 cars. there's only one on obd1. anything 1996+ is OBD2

Re: How many o2 sensors?

There is only one O2/lambda sensor, and it fits into the downpipe (after the flexi pipe). JDM Ludes use an additional temp sensor that plugs directly into the CAT.

2 O2 sensors. One after the flex pipe one after the CAT (on the CAT).
