I did some searching but didn't really find what i needed.

i have a H22a4 swapped into a 92 VX.
using a p13 ECU (ODB1)

i'm pretty sure my 02 is going bad...occasionally I get a 1 & 43 CEL.

i have a 5 wire O2 lying in my garage from the VX motor we took out.

is there a way to use this to replace the 4wire O2 the h22 is using?

also heard you can wire it to run a wideband? is this true?

let me know what my options are.
would prefer to use what i have then to have to buy a new O2

 

anybody????

 

i will take that O2 off your hands if you dont need it PMed you.

 

still need some info on this???

 

your ECU needs a four wire O2, the five wire is totally different and not compatable.
Sell it and buy a four wire.

the VX uses a L1H1 wideband 5-wire O2 sensor. You can create a DIY wideband controller to run it. google DIYWB

 

I think your gonna need to swap a wire from the unused vx plug on the passenger side shock tower to an empty slot on the big plug between a brown and a black wire.... Check it out, i'm not 100% if its the same for a h22, but i think thats what u need to do to run a 4 wire o2
