MAF update and turbo pressure sensor problem

[John B]

Fitted mew Bosch MAF today and then took to have any fault codes removed, the machine told us about the mass air flow but also brought up turbo bost pressure sensor. Could you please tell me where this sensor is and what it does and if I can clean it ???? Terrano 2.7 dti 2004 I've looked on the turbo but can see any type of electrical plug and only a pipe which comes from the turbo up into the activator :nenau. Thanks again

Is it now working ok some1 on here had over boost problem ecu uses maf to tell in a very vague way what boost u have as it sort of know s amount of air going in to engine so there is no sensor for overboost
