Hey Group,

Hope your all well?

After my Escort 1.4i (CVH) L reg failed its MOT, with high emissions been:

Co 6.372 & Hadrocarbons been nearly 800.

This has only just been services. I`ve cleaned all the contacts for sensors
with some contacts cleaner and measured out the TPS and (I think its the
ATS)

I`ve tested the TPS which gives me a value of 0.5v normal and 4.67 @ WOT

I`ve noticed a little unit to the left of my engine which has a hose coming
from my Air Filter housing. I gues this is the ATS?

It has 3 wires on it 2 x Blaxk and Brown, and a Yellow and Brown.

Mesuring Black/Brown to Yellow/Brown on both of the Black/Browns gives me a
value of 2.52v & 10 Degrees, 50 Degrees & 90 Degrees. Mesuring Brown/Black
to Brown/Black gives me a value of 5.05v again at 10, 50, and 90 degrees?

Does this sound faulty? Anybody got any ideas?

I`ve also noticed im only getting about 250 - 290 to the tanks now aswell i
used to get about 350 - 400

Cheers
