Hi,

Can someone please explain these codes

p0571 (16955) - brake switch `A` cir Malfunction

p1128 (17536) - Bank 1 mixture ADAP (multi) too lean

p1539 (17947) - Clutch switch input circuit `f36` implausable signal

p1602 (18010) - power supply (b+) terminal 30 low voltage

p0501 (16885) - vehicle speed sensor A: range perform

Thanks,

p0571 (16955) - brake switch `A` cir Malfunction your brake switch is broken

p1128 (17536) - Bank 1 mixture ADAP (multi) too lean your lambda sensor is dead


p1539 (17947) - Clutch switch input circuit `f36` implausable signal your clutch switch is broken

p1602 (18010) - power supply (b+) terminal 30 low voltage you've disconnected your battery

p0501 (16885) - vehicle speed sensor A: range perform your speed sensor is periodically up the swanny

I think you have some wiring issues around the pedal box.

well put Mork, basically your car needs help

so one (or all) of these codes could be why my car is running like a 1.2L nova?

Not all of them Kris, mainly the "p1128 (17536) - Bank 1 mixture ADAP (multi) too lean".

thanks guys,

anyone know how much a new Lambda sensor is?

 

[Kris]

ok, so I had the codes cleared and the only 2 that returned are...

p0571 (16955) - brake switch `A` cir Malfunction

p1128 (17536) - Bank 1 mixture ADAP (multi) too lean

I have realised that my car is in fact not going into Limp Mode, because I still get 5-6psi of boost.

Could either of these codes cause my car to feal sluggish and just not right!

Thanks

lambda sensor is about £85, easy peasy to fit though.

 

[Kris]

arn't there 2 lambda sensors?

 

[Dormouse]

p1539 (17947) - Clutch switch input circuit `f36` implausable signal your clutch switch is broken

What exactly does the clutch switch do? tell the ECU the engines in neutral? If so, what effect does this have overall?

The code clears but keeps coming back after a a few miles driving but not the instant the car is driven.

Cheers!
