Check turbo presure

Check 1064BA

1.3 JTD 16v

Disconnect the pressure sensor from the inlet manifold.

Connect tool no. 1.870.752.000 to the inlet manifold.

Reconnect the pressure sensor to the other end of the tool n° 1.870.752.000

Connect the pressure transducer to the tool.

Position the Examiner/Examiner Plus diagnostic equipment in the passenger compartment and connect it.

Select the 'pressure gauge' instrument on the Examiner/Examiner Plus and set it to acquire data in 'inlet pressure' mode with full scale of 2000 mmHg and time selection 10 seconds.

Go out onto the road (observing the legal speed limits) and carry out the following test.

On a stretch of motorway, drive the car at 2000 rpm in 4^th gear.

Start graphic acquisition by pressing 'start' on the diagnostic instrument, and after about 2 seconds press the accelerator pedal fully until 3500 rpm is reached.

After reaching this speed, release the accelerator pedal fully.

Display the resulting graph and in the pressure constant part, excluding the initial peak, the reading should be 2200 mbar (abpit 1650 mmHg) corresponding to a turbocharging value of 1200 mbar.

On a fast non-urban journey, drive the car at 2000 rpm in 3^rd gear.

Start graphic acquisition by pressing 'start' on the diagnostic instrument, and after about 2 seconds press the accelerator pedal fully until 3500 rpm is reached.

After reaching this speed, release the accelerator pedal fully.

Display the resulting graph and in the pressure constant part, excluding the initial peak, the reading should be about 2200 mbar (about 1650 mmHg) corresponding to a turbocharging value of 1200 mbar.
