I have a 1993 Scoupe turbo. The wastegate solenoid is either broken or
the hoses are connected incorrectly. When the solenoid is not
energized, the air that comes from the turbo is routed to the
wastegate resulting in low turbo pressure.
This is how the solenoid looks like:
Hose number 1 is connected to the air intake, hose number 2 to the
pressure side of the turbo and number 3 is connected to the wastegate.
Is this correct?
The solenoid seems to work fine, that is why I suspect that the hoses
are not correctly connected.
It seems far more logical if hose 1 is connected to the turbo, hose 2
to the wastegate and hose 3 to the air intake. In this situation when
the solenoid is not energized any pressure in the hose to the
wastegate actuator will bleed off to the air intake. When energized,
the air pressure from the turbo is routed to the wastegate. Is this
how it should be connected?
Maybe someone with a Scoupe turbo can have a look to see how the hoses
are connected? The solenoid is located under the battery. You can see
how the hoses are connected without removing any parts from your car.
The online service manual (thanks Hyundai, this has been really
helpful several times) is not correctly describing my car in this
particular area. In the manual, the solenoid is not connected to the
pressure side of the turbo but to the manifold. This might be
explained by model differences between the cars from the US and the
Thanks in advance.
