Camshaft Position Sensor Power Supply
Inspection
1. Turn the ignition switch to 'ON' position.
2. Disconnect the camshaft position sensor connector.
3. Measure the voltage between the No.1 and No.3 pin of
camshaft position sensor while the ignition switch is in "ON"
position.
Notice
If the measured value is not within the specified value, check
the cable.Notice
The signal voltage will be changed in the range of 1.2~1.7V.
Camshaft Position Sensor Output Wave
Inspection
1. Connect the test box to the ECU.
2. Measure the output wave between the ECU terminal No.104
and No.106 using the scanner or the oscilloscope while the
engine speed is at idle.
Notice
Replace the camshaft position sensor if cannot get the
output wave as shown in the figure.
Specified Value 11 - 14 V
Specified Value 1.2 - 1.7 V
Camshaft Position Sensor Signal Voltage
Inspection
1. Connect the test box to the ECU.
2. Measure the voltage between the ECU terminal No.11 and
No.106 while the engine speed is at idle.

Test Procedure
1. Remove the fuel filter (1) and keep the filter not to be
damaged from running engine.
2. Remove the vacuum line (2) from ancillaries connection (3).
3. Connect the vacuum tester (4) to the ancillaries connection
(3).
Vacuum Tester 201 589 13 21 00
4 Run the engine at idle and check vacuum pressure after 30
sec.
Notice
If out of standard, replace the vacuum pump.
5. Remove the vacuum tester.
6. Connect the vacuum line to the ancillaries connection.
7. Install the fuel filter.

3. Disconnect the vacuum hose (4) from the PLA unit to check
idle speed with tester.
4. Check idle speed with tester.
Notice
To adjust idle speed, loosen the locking nut (6) of PLA unit.

6. After adjustment, tighten the locking nut and place the
position marking with different color of paint.
Notice
If there are no changes in idle speed with PLA unit
adjustment, perform the service at a BOSCH Service Center.
7. Connect the vacuum pump to the PLA vacuum unit and
build up vacuum approx. 500mbar. If engine rpm increases
by approx. 100rpm, It is normal.
Vacuum Pump 001 589 73 21 00
8. Connect the vacuum line (4).
9. Switch on all ancillaries and check the idle speed.
5. Ensure not to damage the idle spring in the governor and
adjust idle speed by turning the PLA unit (5) slowly.
Notice
Do not rotate the PLA unit over ½ turn from the position
marking. If do, idle spring in the governor will be severely
damaged.Clockwise

7. Check the fuel injection nozzle and adjust opening pressure
if necessary.
Opening pressure adjustment
Disassemble the fuel injection nozzle and replace the steel
washer (2).
Notice
Each 0.05mm thickness of the washer results in a pressure
difference of approx. 3bar.
