TURBOCHARGING PRESSURE CHECK

Check 1064BA

1.3 Multijet

Fit pressure relief sensor (2) on tool (1) N° 1871003500 and secure it using bolt (3).

Connect the electrical connection to the pressure relief sensor.

Connect onto tool N° 1871003500 tool EX09 (4) contained in case N° 1806338000 and connect connector (5) N° 2000017500

Connect 5 bar pressure transducer EX06 to the tool and connect it to the Examiner Sam card using cable EX01.

Position the Examiner diagnostic equipment in the passenger compartment and make the connections.

Select pressure gauge on the Examiner and prepare to download data in intake pressure mode with a 2000 mmHg full scale deflection value and selection time of 10 seconds.

Road test the vehicle (respecting the speed limits in force) as follows:

On an out of town route with 3rd gear engaged

Initiate the download by pressing start on the diagnostic equipment and 5 seconds later fully depress the accelerator pedal until the engine speed is 3000 rpm.

Once this speed is reached, completely release the accelerator pedal.

Display the resulting graph and read a value of 2100 and 22300 mbar for the maximum peak (1596 - 1748 mmHg), corresponding to a turbocharging value of 1100 - 1300 mbar.

Disconnect the Examiner and the pressure transducer.

Detach the electrical connection from the pressure relief sensor.

Unscrew the bolt and remove the excess pressure sensor from the tool.

Remove the tool for checking the turbocharging pressure.
