TURBOCHARGING PRESSURE CHECK

Check 1064BA

1.9 JTD 8v, 1.9 JTD 16v

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

Connect the electrical connection for the pressure relief sensor.

Connect the EX09 tool (4) from box N° 1806338000 to tool N° 1871003500 and connecto connector (5) N° 2000017500

Connect the 5 bar pressure transducer EX06 to the tool and connect it to the Examiner 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 for the acquisition of data in "intake pressure" mode with a 2000 mmHg end of scale and selection time of 10 seconds.

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

On an out of town route with 3rd gear engaged

Initiate the acquistion 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 supercharging 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 supercharging pressure.

Proceed with refitting the excess pressure sensor

Check the supercharging pressure. Fit the excess pressure sensor on tool N° 1871003500 and secure it using the bolt.

Connect the electrical connection for the pressure relief sensor.

Connect the EX09 tool from box N° 1806338000 to tool N° 1871003500 and connect the connector N° 2000017500 (as can be seen in Fig. 1).

FIG. 1

Connect the 5 bar pressure transducer EX06 to the tool and connect it to the Examiner 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 for the acquisition of data in "intake pressure" mode with a 2000 mmHg end of scale and selection time of 10 seconds.

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

On an out of town route with 3rd gear engaged

Initiate the acquistion by pressing start on the diagnostic equipment and 5 seconds later fully depress the accelerator pedal until the engine speed is 4500 rpm.

Once this speed is reached completely release the accelerator pedal.

Display the resulting graph and read a value of 1900 and 2000 mbar for the maximum peak (1444 - 1520 mmHg) corresponding to a supercharging value of 900 and 1000 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 supercharging pressure.

Proceed with refitting the excess pressure sensor
