Volvo 850 ob1 question plus dash lights. New hobbiest
 

Hiya guys. Hope everyone is well!
I've got a 1994 Volvo 850 SE. With the 2.5litre engine in.

Bought with the lamda light on and known but engine seems to run with no issues.

Eitherway first question if possible
My OB1 A and B bank don't seem to have all the connectors you would put the pin into.
On A I have only A2 A3 and A7. Doesn't seem to have any cut wires or anything unscrupulous going on. Did some of the base spec models come with less?


Regarding the lights I've currently got the Lamba and a flickering ABS warning light.

So I have read the codes which are as follows.

A2. - 112

A3. 141 + 142

Now I know 141 is the break pedal pressure switch. Which I believe is the big sensor looking thing attached to my brake booster.

142 is a faulty stop lamp switch.


But I'm not sure what A2. 112 is. And could this cause my lamda sensor.


If not what would you recommend I check for to hopefully cure this :)


Oh btw it's on 125,000 miles!

All the best and massive thanks in advance ❤️

Hiya chap. Thanks for clearing that up
As someone who's not that clued up on the electric side ( previous classics are from the 50s lol ) what does that mean exactly :p
