Hi George,

This vehicle does not have a MAP sensor. In its place is a TPS which tend to give problems similar to what has been described. Need more info please such as fault codes and emission readings if possible.

Hi chaps i had a better look at it and the stepper motor is't working althow it has a new one on and is also overfueling. could the stepper
be responcible for this or is the ecu capout?
thanks george

HI George,

Stepper motor works in conjunction with tps. Proper testing and info required otherwise it is a guessing game.

>>> stepper motor is't working althow it has a new one on <<<

That will be the last garages "FIX" then.

Why do people fit components without testing the circuit ?

yes customer changed a lot of parts with his mate
he said he baught the stepper motor from the ebay but it does't seem to be moving atall and there's a fault code in the ecu for it.there are
3 wires with battery voltage and 3 with earth in it's plug. the tps has 2 signals 1 with 0-4.30v and 2 with 640ms-4.92v the os is switching well
but the injector is paulsed at 2.2-3.1ms insdeed of 1.9 according to a.data so it's overfueling
so what do you thing could the dead stepper motor be causing the overfueling ?

ahhhhh, This sounds like the same system as the old corsa's, ?? Have they messed about with the throttle cable and adjusted it too tight. ??? If they have, The lever wont return fully and fails to press the switch on the end of the stepper motor plunger, which will cause it to surge and stall.

We used to replace lots of these stepper motors and we did have a couple of occasions where the ecu was also faulty on that circuit.

There are also some Fake stepper motors available for these which aren't as good as the originals.

H.T.H Tony.
