[seahaven car imports]

hi surfers!please can you help?i have recently sold a 93 2.4 td ssrx to a customer who has now experienced a small problem with it!i have had it back to look at,but have not found the cause yet!!

if you keep your foot hard down on throttle,as if you were overtaking!when it revs round to just past 4000 rpm in second gear just before it changes gear the check engine light comes on,engine does not cut out,then if you lift off throttle light goes out?????????????

can anyone help!comes up with fault codes 2 and 5?where is the turbo boost pressure sensor?

On a 3.0, its on the underside of the intake manifold, at the front. Not sure if the 2.4 is the same.

The Sensor is at bottom/centre of pic on side of filter housing.The hose from this goes to the small filter and then to a bigger hose under throttle housing.The T piece in this pic with extra hose is for a Turbo Pressure Gauge.

Try the actual electrical connection to the Turbo,it's a black plug near your right hand battery. It may have come partially disconnected. This happened on mine and prevented the turbo from working correctly.
