Hondata

Hi
I have a JDM K20A (from a 02-05 integra) with a PRC ECU

I have purchased a O2 (or Air/Fuel sensor) sensor - its a wideband
Honda 36531-PRB-A01 ( I have the equivalent Denso 234-9005) as suggested.

Can anyone please tell me the wiring - it has 2 black wires (I presume heaters) 1 x blue wire and 1 x white wire (presume signal).

As stated I also am thinking white is sensor signal. This is going into a Lotus so I have no "socket" to plug into! so need to hard wire.

It is safe to presume
PHO2HTC+ goes to A22 white (sensor black wire 3rd pin and also switched by relay)
PHO2SHTC goes to A1 black/white (sensor black wire 4th pin)
PHO2S- goes to A16 red/yellow (blue wire 2nd pin)
PHO2S+ goes to A6 (white wire 1st pin)


I have gained this info from a RSX S manual.

I don't have this info at the moment as I was give the instructions that applied to a PRA from the UK.

I am in Australia - the conversion is now complete apart from this problem.

Currently the K-Pro is showing a P1166

Thanks

For the wiring the Honda ETM manual has the pinout and colors for most connectors.

I would always recommend a Honda sensor from a DC5 or EP3 as many suppliers supply incorrect sensors - we've seen listings for the same sensor for the 02-04 and 05-06 RSX, where they actually use a different sensor. If you are using an aftermarket sensor then you should test it for several driving cycles in a DC5 or EP3.

P1166 is a heater error. Do you have the o2 sensor heater relay wired up correctly? Is the ECU energizing the relay correctly? Is the o2 sensor heater working?

Thanks
the part number 36531-PRB-A01 is listed on http://www.hondata.com/techk20-ctr-o2wiring.html - so I thought that was the right one.

Denso claimed Denso 234-9005 was an identical part.
I will have one last look at my options. If it doesn't work then I will need to purchase a 36531-PRB-A01.

Hey - great software by the way.

I have sorted the problem out - it was due to the blue and white wires being reversed - so the Denso DOES WORK WELL as a wideband.
