Gal Needs Help

[steve2908]

hi all.

my gal (and me) need help.

she is ill and goes into limp mode quite alot?

i have a fault reader, and when plugged in, throws up code 00575 which reads manifold absolute pressure sensor.

i have looked for this sensor in my haynes manual but it isnt listed in there?

does anyone no where this sensor is situated and the price and best place to buy one?

she wants to tow a caravan very soon but at the moment is too ill to manage it. once she gets this sensor she will feel a lot better (i hope)?

the car is a 1997 1.9 tdi ghia 80ps

 

hope someone can help her?

 

thanks.

Isn't the MAP sensor part of the dreaded MAF on these donkeys?

 

Sounds like classic TDi MAF problems to me. Have you unplugged the MAF and tried the car?

hi.

i thought the map sensor is completey different from the maf?

anyway when i 1st got the gal the maf was knackered ,maf was showing on the fault reader, so i changed the maf for a new one, and the fault didnt show anymore one the fault code.

but now its reading the manifold absolute pressure sensor as faulty.

i have also had other things done like new fuel pump and cambelt etc.

but its always gone into limp mode since ive had her?

only seems to go into limp mode when trying to accelrate up hills or when loaded?

00575 Intake Manifold Pressure: Control Limit Not Reached.

 

This is probably not a faulty sensor (which IIRC is mounted on the large black intercooler pipe crossing the right side of the engine).

 

The fault means that the ECU demanded turbo boost but insufficient boost appeared. The usual reasons for this are

 

1. Leaking/disconnected/blocked vacuum pipes

 

2. Faulty/blocked Turbo control solenoid

 

3. Sticking turbo waste gate actuator (90bhp model)

 

 

Check all those little vacuum pipes first, start at the turbo and work back.......
