O2 sensor How many and where on a 94 J30

Post by **craze K** » Thu Jul 31, 2008 4:08 pm

Can anyone tell me how many sensors are on the 94 J30 and where would they be located? I went to oxygensensors.com and found some that said Pre-cat left and pre-cat right. Do I need 2 on each side or are thier different ones for another area of the exhaust. If so what would they be called? Thanks for any advice you can give me.

94 is OBD1 which means it only has O2 sensors in front (pre) of each cat. You have 2. One on each side. They will be just upstream of the cats.
