Boost Pressure Sensor A Circuit

[wadeyykerr]

hello, boost pressure sensor circuit A has thrown up on codes, are these 3 the only boost pressure sensors and are they all the same sensors or should they be different ones? Bosch ones have been changed already.

constantly in limp home mode.

The image with the DC part is the part for the only sensor that has not been changed.

thank you.

Middle 1 is the map. It's a bolt missing.

thank you, yes i’ve just dropped the bolt when undoing it (useless).. what about the other two what sensors are they?

so the one with the screw missing is the map sensor?

It's the boost pressure sensor. Other 1 is intake manifold pressure sensor.the DC 1 is also a manifold pressure sensor.

ok thank you so the one in my hand is what was originally there and put the other one in, so that will be the wrong sensor then i guess grrrrr

I think the one in now is correct. Put your vin in 7zap and search engine electricals. Itll tell you .

The dc one I'm pretty sure goes where the throttle body is.

i’m looking but can’t see engine electrical anywhere.. this car is the bane of my life. even garages can’t think why it’s in limp home mode

What's your vin.

 

[wadeyykerr]

What's your vin.

i believe i’ve found it now, it’s WDD2073032F064970

a007 153 00 28 and 261 230 439 are the same part, which leaves a0061539728 the first image above.

thank you mate, it’s so confusing because it looks like it’s the same sensor that i need for each location
