Nissan Primera P11 144 Error code P0135

Hi guys,

Sorry to resurrect an old topic but the P0135 error on our 1.8 P11 144 is still there.

The car passed it's MoT ok a few weeks ago.  I did have to reset the MIL though as with the MIL on it wouldn't pass it's emissions test.  Soon as i reset the light, all the readings were within range and it passed just fine.

So obviously the car is in limp mode, and it drives a bit sluggish, fuel consumption is also out.

As some of you may remember i've been through what i understand to be working sensors and the problem is still there.  I've just tested the voltage from the harness and i'm getting battery voltage at terminal 3 which says to me that the harness/ECM etc are ok - or am i making a wrong assumption there?

So could it be that i have been through duff sensors, could it be that coincidental?

I've tried to test the resistance of the sensor but i can't work out which settings to use on my multimeter. 

On the multimeter i switch it to the horseshoe symbol but should i have it on 2000k, 200k, 20k, 2000 or 200?

Also i have 3 terminal sockets on the meter.  A COM (which i expect is just ground) and then a V *horshoe* mA FUSED and then an UNFUSED 10A Max.

Which terminal do i need to use?

Sorry for all the questions, i just want to eliminate the sensor itself as being at fault before i go about replacing it.

Again, just to reiterate, when i reset the light i get perfectly good readings from the OBD2 software and of course it passed it's MoT!!

People have said there is a 10A fuse located somewhere that could be blown, but i can't work out which fuse it is.  Can somebody confirm this for me please?  Also if the fuse was blown theoretically it shouldn't send the battery voltage to terminal 3 should it?

Anyone local to West Yorks who fancies having a quick look at it with me?

Really hoping somebody can help me sort this out.  Car really is troublefree otherwise!

Cheers

Right,

Quick update on this.  I managed to check the resistance of the sensor.

With the engine running so the sensor is warm, it was chucking out about 5ohms of resistance value, so according to the service manuals, this is within tolerance range.  Also there is no continuity at all between terminals 1 and 2 or 2 and 3.

I also have a spare sensor, and although this was cold and not in the vehicle, it checks out fine with the multimeter.

The wiring harness is chucking out 14v (Battery voltage) from terminal 3.  Terminal 2 i suspect is ground as there was nothing from that.  Terminal 1 is chucking out about 4 - 5v.  Can anyone confirm if that is normal please?

So all i've really managed to determine is that the wiring is probably ok, the sensors are both fine.

But the problem of error P0135 is still there!!

Where do i go next with this guys?  Does anyone know how/where i can check if the ECM resistor is ok?  Only reason i ask is that the FSM says it's possible to damage the ECM resistor.

Is this an integrated component on the ECM which can not be replaced in isolation? (hope not).  Going back to the question of cam position sensor, this was done by Nissan under warranty but the P0135 was already there when it went in.

My gut feel is that the universal sensor i fitted for a while has done some kind of damage as the error appeared whilst this was in the car.

I haven't removed the rear o2 yet but as the error is specific to Front o2 Bank 1 sensor 1, i didn't see the point.

If someone can tell me whether the rear o2 could cause P0135 then i'll remove that too.

Please help if you can
