New map sensor

Two months ago I fitted a new map sensor bought from ebay (£35.00) I thought I would give it ago as the original one was looking bad even after cleaning it. The new map once fitted did improve both the turbo pick up and smoother running of the engine. I did notice however that the turbo gauge did not go back to zero at tick over but it didn't bother me.

Last weekend the EML came on and the turbo gauge started bouncing from zero to full when driving and the turbo was sometimes working then not and the performance was gone.

The fault codes were P010F, P0235 and P2111.

Thankfully I had not thrown away the old map sensor and fitted it back. The EMl went out after five restarts and it was back to normal but with a slight poorer pick up again.

I have just bought and fitted another new map sensor this time a facet brand from here:

Alfa Romeo 159 Sensors

Everything is back to normal and the performance also is very much improved. I will see how long this one lasts.
