P0642

[Danboii]

Iv got the code p0642 sensor A reference voltage circuit low and one know what this is and what I can do 

[Steve Q]

Does it say what system it's in relation to? 

[Danboii]

Just says reference A 

[Steve Q]

It could be an intake flap motor (most likely) or technically any sensor that draws 5 volts.

Had a look earlier and there a broken plug to the oil level thing and my break sensors wires are completely snapped but I don’t think these would put the car in limp mode or am I wrong 

[Steve Q]

Definitely don't think the brake pad sensors would put it in limp mode. But not sure about the oil level situation. Is that down to a sensor I wonder? If so then hypothetically it could be this. 

[Danboii]

It says a bad sensor or a broken cable

I'd definitely be getting an auto electrician to conduct a full investigation.
