I have a 92 VX just got a ZC SOHC vtec dropped in and its not reading my O2 Sensor any help would be appreciated im using a p28 ecu

 

is that a 4-wire o2 sensor you got?

 

just disable the o2 in the ecu

 

its a 5 wire o2 sensor .... and its eating up gas like nothing right now!!

 

for the p28 you need a 4-wire o2 sensor... what does each of the wire do for that 5-wire o2 sensor... you might be able to get it to work... the 4-wire has 2 wires for heater, one signal and one ground

 

convert your 5 wire o2 to 4 wire.

exactly
a P28 needs a 4-wire O2.

 

does any one know how to convert the 5 wire to a 4 wire?? if so can you help me out?

 

is there no one that can help??

 

if you have the OEM 4-wire O2...

white wire(O2 signal) connect to the orange/blue wire on the VX O2 plug
green wire(O2 ground) splice into the green/white wire on the IAT or TPS.
black wire(heater control) connect to the yellow/black wire on the VX O2 plug
black wire(heater power) splice into the yellow/black wire on the EACV or injectors
(the drivers shock tower has a bunch of them connected together also)
