[rifdi]

i installed an apexi turbo timer into my honda accord but the 02 sensor and a/f is not functioning..can anyone tell me the reason and where to fix it

maybe wire....

or maybe your o2 sensor went "kaput".if i'm not mistaken ur's is
a 4 wire narrow band sensor.try look at the chop shop.
it would be a lot cheaper then a new 1.new 1 cost around rm700.

how much is the market price for a 4 wire narrow band? i think i got 1 for sale....

 

[rifdi]

is that a honda accord cb7 ?? im driving one of those too..but i changed the engine..do u install the apexi turbo timer?if u do does it work?

and if i get the o2 sensor from chopshop and the 4 wire narrow bend sensor will it work??

if ur o2 sensor kaput, maybe the engine check light will light up.
check ur timer wiring 1st.

4 wires o2 narrow band usually are with heater.
- 2 wires for heater.
- 1 ground
- 1 sensor signal

u must tap the signal wire. either from ecu or the sensor itself.
