Required special tool
- Mot. 997-01 Nozzle removal tool.
- Mot. 1140 Tool for removing the height corrector.
Tightening torques, Nm
- Altitude corrector: 30.
1 - Plug.
The corrector regulates the performance of the pump depending on the height above sea level; if the vehicle is driven at an altitude equal to or greater than 1000 meters, the computer reduces the output by 3 mm/cycle. It restores normal performance when the altitude at which the car is moving is less than 900 meters.
Removing
1. Remove the high pressure pipe.
2. Remove the nozzle (cylinder #3) with built-in needle lift sensor using tool Mot. 997-01.
3. Disconnect the injection pump connector.
4. Disconnect the high-altitude corrector wire lugs from the pump's 10-pin connector.
5. To disconnect the tips from the pump connector:
- pull the yellow plug 2 towards you to disengage it from the lugs, then press the two latches located on both sides 1 of the connector;
- pull out the yellow guide plug;
- tension the removed conductor;
- the tip is fixed in the connector with latches located on both sides; use a screwdriver to pry out one latch (a stretched wire does not allow the latch to return to its place);
- press the other latch with a screwdriver;
- remove the tip from the socket.
6. Remove the protective cover covering the height corrector.
7. Remove the protective cap from the solenoid valve.
8. Remove height corrector 1 using tool Mot. 1440.
A - Groove for skipping the connector.
Installation
1. Be sure to remove the small mesh filter installed at the bottom of the channel. Use tongs with thin sponges for this; replace the filter with a new one.
2. Tighten height corrector 1 to 30 Nm using tool Mot. 1440.
3. Put a new protective cover on the height corrector.
4. Connect two lugs to the connector.
5. Connect the connector.
6. Install the protective cover of the harness and its retaining ring.
7. Bleed the diesel fuel circuit with the booster pump before starting the engine.
