yeah, denso diagrahm offers 2 connection types for honda, however, the connector type that i have uses blue to white and white to green. i don't know how its wired up internally.. maybe it don't make a difference if you swap the 2 with one another.. but i'll go with what DeDonDeRosa says and diagrahm. thanks all for helping

This picture is WRONG!

I just connected white to blue, and green to white and got rid of CEL light.

First I tried as in your picture and CEL was coming back. Maybe it's different in europe ( I see you are from Europe), but I doub't it.

Here is official NGK website, which shows both DENSO sensors.

Signal + White = Blue
Signal - Green= White
Heater Black=Black
Heater Black=Black

no need to be a ******...******.... regardless of what 'brand' the sensor is, the hookup if will be the same if the wiring colors match

Could you support your instructions you posted in another post ?
I don't want to be arrogant, but I think you are wrong.

Green wire on original Honda Denso sensor is not a signal wire.
Signal wire is white.

I can confirm this with NGK website &gt;

Look for Honda and 4 wire sensors. There are two denso sensors
Blue = White &gt;&gt; Signal +
White= Green &gt;&gt;Signal Ground


In Honda Service manual it shows that White is Signal wire and Green is ground.


And lastly, I just replaced the wires myself and can confirm that white to blue, and green to white is right way to connect.
