Brakes: 850: Lots of fault codes :(

[ewanc0]

Decided to read the codes as the ABS light keeps coming on and i got.....

1-4-1 faulty brake pedal position sensor, shorted to earth or supply
1-4-2 faulty stop light switch, open circuit or short curcuit
2-1-1 LH front sensor - no signal when moving off
2-1-2 RH front sensor - no signal when moving off
2-1-3 LH rear sensor - no signal when moving off
2-1-4 RH rear sensor - no signal when moving off

Now i've cleared the codes but not had a chance to take it for a run but what do you think these are pointing to?
I'm inclined to think it's a single fault causing the above but unsure where to start.

Thats kind of what i'm thinkiing. Is there a way to test it or is it a case of replace and see what happens?

there are a lot of threads on this for a fix doing the dry joints, but if your not handy with a bit of soldering maybe a second hand unit .have a look at this thread

I think someone on here a while back told me that the one i have doesn't suffer from this problem

I run my 94 turbo and regularly get 1-4-1 and 1-4-2 codes. This sensor is on the brake booster and there are write ups for repairing the contacts inside. I haven't had the guts to do mine yet.

The others should go away once you have reset the ecu. If they come back there is a fault, probably with the wiring. Do you have the tracs set up?
