D4D Cheak Engine Light

[gerry68 0]

hi all

im a new member ,

i bought an 2004 2.ol d4d avensis last week ,on the way home the cheak engine light came on

i looked it up and the most common fault listed was the egr valve sticking

so i cleaned it up and the same problem came up .code was p0400

i got a second hand unit same problem came up so i just bought a new one .

even with the new valve the same problem came up

i took the first valve off and cheaked the air flow coming from the exhaust and the vacuum going into the inlet and neither where not blocked ?

so im thinking either the stainless steel gasket has a problem or the sensor picking up the gas flow into the engine is a fault .

any help would be greatly apperciated thankyou .

Got it sorted

The air intake manifold was stuffed up with carbon soot .

Took it off and cleaned it out .

Alls fine now

Sat in the drivers seat it's just below your right knee and it has a little plastic cover on it which just pulls off.
