[R402faa]

Hi as above I have the service vehicle soon on the dash had the car scanned and came up 1035 which the mechanic said it was my lamber sensor iv now replaced the sensor will the code clear on it own in time or is it a trip bk to the garage to get it cleared
Thanks jamie

Is the EML still on?

No just service vehicle

If you've replaced the O2 sensor and still having a light on the code will be stored so will need plugged in to reset

OK thanks

Which 1 did they replace ?
Bank 1 sensor 1
Did they do any diagnostic procedures to see if it was the sensor or wiring?
If all is ok and you are sure the fault has been cured
I don't know if with them they need to be coded to the car .
But you could always disconnect the battery from car for a couple of hours to see if it clears
But make sure you can re-enter the car before disconnecting ( i.e. Key fits and turns in door lock barrel and it unlocks car .)
10-4 good buddy

Some dtc codes will clear themselves after a certain number of runs without the fault being detected others will manually have to be cleared.
With a good diagnostic tool you will be able to see when connected live data that will help you to identify if the sensor is working correctly and depending on the vehicle you will be able to preform actuation tests.

On some Vauxhall you may also need to do a HO2S Learn with a diagnostic tool i believe but maybe someone would be able to clarify this further as i am not sure if the car will learn this themselves or if this can only be done via oe level tool

On Thease there is a learn process, as you know most things on modern cars is not a case of plug and play .
The op has not put down engine power output etc etc and year ,
There are 2 o2 sensors from the code its bank 1 sensor 1 .
But he dose nit say if the garage he took it to carried out a diagnostic test to see if it was the sensor or a wiring issue ,
If the 4 wire type there's a power ground , heat ,signal.
But from what I've read they diagnosed and he replaced it .
It requires learning/ codeing which most non dealership diagnostic equipment can carry out .
But that's if it was the sensor and not wiring at fault.

That's why your always best to re read ECU for codes after clearing if light doesn't go out. Lol

[ThinkDiag]

I know a tool that would allow the learning depending on the model and year hint hint : )

Bit pricey for me tbh Inc yearly subscription

The price is actually very good for a OE level tool considering if you buy the pro3 uk version it would be i guess 1500 and you would still need to pay to update the brands after a year or two still anyway. The downside if anything due to the cost is that it only comes with two free software for 12 months but if you want OE level diagnostic on a limited number of vehicles you will struggle to find a more affordable option. having said that this tool is not for everybody and i respect that some people need all brands so could work out cheaper to buy the pro3 and other people only need basic code reading and clearing.

You would have to check it supports what you need it to but a op-com could be a cheaper alternative for you but this will not have the same power as the thinkdiag another alternative could be the ap200 but this tool is not bidirectional.

Op com and the like of do a good enough job for me no subscription etc, I own cars general for long periods of time so would be more cost effective not to have subscription and a tool per say for that vehicle.
Sounds the part and wish you luck selling your products

If op-com works for what you need and on your vehicle year that is a wise decision
