New code.....any ideas please.

[V70 Graham]

it did baffle me a bit as too why they changed the rear sensor when they knew it was the front one, especially when the code returned straight away. Are they using Vida Dice for diagnostics or something else?

They have VIDA/DICE

They did change the front one first but the code came straight back, now they say the rear.

Acording to there diagnostic machine, scanner, code reader call it what you like.

It said Bank 1, Sensor 1, (Sensor 1 Front) (Bank 1 Primary cylinders)

Do they understand the difference between Bank 1 and Bank 2, sensor 1 sensor 2? here below have a read

Tbh we have never had a issue with NGK sensor's they are Oe to most Premium Brands of vehicle, that's not to say they never fail, but its unsual for the lambda tobe directly at fault.

Hope the link above helps

Just to note have you tried to reset the ECU to factory default? perhaps the ecu didn't like the 1st pipe you fitted/items fitted, and is causing the voltage to fluctuate on the primary sensor (just a thought) im not ofay to me7 volvo's

Surely clearing the code would be as good as resetting the ECU, also it's a remaped ECU, so not sure Graham would want it reset to factory default.

no clearing the code will not return the car to factory setting, on a pre me7 car you disconnect the battery for 10 mins. (you will not loose the map) on a pre me7 car.

[deathrider311271]

on Vida Dice there is a set procedure too reset the codes and this procedure resets all the core values back to factory settings, it will not affect the remap in anyway, however if they havent reset it correctly it will come back straight away

No I didn't think it would reset the car to factory default, just thought if the code for the lambda was reset then no code would appear again unless the lambda was faulty. TBH my money is on the part of the engine loom the lambda connects to as it's been fiddled about with so much recently, there's a chance a wire could be brittle and have broken. Graham's is ME7 .

[merc85]

Graham's is ME7 .

I relise that which is why I was only refereeing to a pre me7 car didn't know if it was the same, has ive little experience working on me7's Volvo's, I was waiting for someone ie deathrider to explain, which I feel he did.

you could well be right as i have the same problem on mine, its a bloody pain as i need too lay my hands on a wiring diagram to find out which pin/s in the ecu corespond to which wires on the front lambda. Then i can check for power/continuity.

If i find anything Graham i will give you a shout but it will be a few weeks yet.

I am sure a workshop code reader should give a scope type read out to see if it's getting any type of input from the sensor,from engine off to running and hot.

VIDA dice will only do a reset if the fault is not present when the reset procedure is carried out,if the fault is present it will not do the reset,and say it failed to reset.

Like you say.

When I had my Cougar, I had a Snap on Solus hooked up to it to find out which lambda was faulty, and it gave live readings of voltage from each lambda (well only one lambda as the other was dead and giving nothing) does VIDA/DICE not do the same thing?

Sorry mate wasn't having a go, just telling it as I saw it/ my train of thought went, I don't really know either. We'll just call it brainstorming.

I think so never seen it used for this.

He who should not be named had a the same fault on he`s V70R.

Once resetting it would stay off of a while then come back on, It was found to be a knackered cat.

Is Graham`s new cat a Volvo one or a aftermarket one ??

As it's Graham, I'm guessing it's a Volvo one.

Thanks this is going to be a good read.

Aftermarket.

Its M4.3/M4.4 and Fenix5.2 unfortunately bud.

Anyway, ecu is on page 17 and O2 sensors are items 7/15 and 7/82

[oblark]

Aftermarket.

There`s be your problem.
