My 1996 SC400 engine uses 4 wire O2 sensors and both need to be replaced to cancel the error codes.
My question is, will any 4 wire O2 sensor work or are there operating parameters or thread size differences I need to be aware of. Alternatively, is a single or dual wire unit compatible. This is a new area to me.
