02 Sensor/ CPL Manifold

Terry H · 24th June 2009, 22:17

I have Hondata Ecu and a CPL manifold, I cant get my engine management light off, I'm just using the pre cat Lambda sensor, I have changed the sensor but when I get the ECU reset the light comes back on, The car runs fantastic but I have no idea why its coming on
On the diagnostic computer it says its the heating circuit within the O2 sensor.
Has anyone else had problems or can anyone shine some light on what's going on,
Thanks all.

Terry

Perhaps you have had remove wrong sensor? Please check it once again! You shoudn't have any warnings lights. If this not help, i think you should call Guy at CPL and talk to him. Please swap the sensors and let me know.

Cheers

yea thats wierd there shouldnt be any warning light..the hondata wipes that out..either that or its somthing else in the engine lol

Hi Terry,

It sounds like you have pulled a wire to the o2 heater.

Thanks for the reply's, Its the Pre cat / blue socket im useing, I was there when the manifold was fitted I didnt see any tugging of the cables.

Guy, would I be able to do a continuity test on the cables ? do they go directly to the ecu ? which colour is the o2 heater cable.

I didnt have any problem with the light until I fitted the manifold so I dont think there is any engine fault, the car funs fantastic.

Again thanks for the help.

Regards
Terry

hi terry,

I had the same problem at that time.
for me it was because I had installed the wrong sensor.
replace the sensor and the problem should be gone.

Terry H · 25th June 2009, 17:49

Again thanks for the help.
Ok there are 2 sensors, Pre-cat which has a blue socket and one in the middle of the cat which has a green socket.
I have left the green socket taped up, I have used the Blue/pre-cat sensor in the manifold.

Im sure this is correct.

Thanks Terry

I hear what your saying about trying the other sensor, But ! when the car was plugged in to the computer it did say the second sensor was disabled and it was the o2 heater circuit on the pre cat sensor that was cauisng the fault,,, Can you remmeber weather you used the blue or the green connector on the sensor, as I have stated im useing the blue one.

regards Terry

I understand!
you have both sensors build out and now you no longer know where which sensor was installed?

Hell no, lol
I have not removed the Green socket sensor from my cat, I have always used the Blue socket pre-cat sensor in my CPL manifold.
I just thought you knew something I didnt.

I firstly used my original sensor and I extended the cables and the fault appeared, I thought maybe dodgey solder so I bought a new one, when the socket is removed from its holding bracked the new sensor not extended fits, I got the ECU reset and the light came back on straight away.

So its got be baffled.

NDFN2 · 26th June 2009, 21:16

you must build-in the green sensor from the oem-kat, so you have must install the sensor into the cpl manifold.
but you have to extend the cable beforehand.

or did you already tried this?

I do not quite understand you!

Ummmmm I could be wrong BUT ! I just cant work it out why you would use the green sensor,,,

NDFN2 · 26th June 2009, 22:12

because, if the blue does not work and brings the error, then it must surely be the green?

it is already more than a half year ago where i have fittet the manifold.

so unfortunately I can only make guesses.

Just try it, it can not hurt them take!

the error is there = false sensor
the error is not there = right sensor

I hope your right it will be a quick fix which will make me happy but what im worried about is a fault in the cable from the sensor to the ECU. or worse case a problem with my beloved Hondata

NDFN2 · 26th June 2009, 22:34

good luck and let me know!

PS: i know that this fact is somewhat confusing!

Terry H · 27th June 2009, 10:37

Can anyone help me out and tell me which sensor is used in the CPL manifold, theres the blue socket precat lambder or the Green socket sensor which is set in the middle of the cat.
Like I have said im using the blue one but it would be nice to know before I start hacking the green sensor and extending the cables.
Cheers

Terry

I think you should email Guy from CPL guy@cplracing.co.uk and ask these question.

Cheers

Terry H · 27th June 2009, 22:27

Thanks Dawid, I think its the blue one to but Ill give CPL a call after the weekend hopefully Ill be able to get sorted, im going to try and get a wiring diagram and see where the cables from the sensor go to. I dont think its effecting the performance at all the car is going very sell so at the moment im not to botherd.

regards
