CHECKS : TURBO PRESSURE
Engine : 4HX
Preparation of tools : in position on the vehicle (continued).
Screw the tool [3] on the take-off of the turbo air radiator at «c».
Place the pressure gauge on the cup holder at «d».
Connect the extension [2]on the hose «b»and tool [5].

- Start the engine.
- Engage first gear and start the vehicle.
- Engage the gears up to third gear.
- Decelerate to1500 rpm.
Accelerate gradually : the pressures should be the following :
1,1 ± 0,05 b at 2000 rpm
1,2 ± 0,05 b at 3000 rpm.
Return the vehicle to normal.
Remove the tools [1],[2], [3], [4]and [5].
Reposition the pressure sensor (3).
