STEP 13. Measure output waveform at B-106
camshaft position sensor connector (Use
oscilloscope).

œ

Use special tool test harness (MB991709) to con-
nect connector, and measure at pick-up harness.

), its maximum value

should be 4.8 V or more, and its minimum
value should be 0.6 V or less with no noise in
waveform.

Q: Is the check result normal?

YES :

Go to Step 9 .

NO :

Go to Step 14 .

STEP 14. Connector check: B-17X engine control
relay connector.

Q: Is the check result normal?

YES :

Go to Step 15 .

NO :

Repair.

STEP 15. Check harness between B-106 (terminal
No. 3) camshaft position sensor connector and
B-17X (terminal No. 1) engine control relay
connector.

œ

Check power supply line for damage.

Q: Is the check result normal?

YES :

Go to Step 16 .

NO :

Repair.

Code No. P0403: EGR Control Solenoid Valve System

OPERATION

œ

Power is supplied to the EGR control solenoid
valve (terminal No. 1) from the engine control
relay (terminal No. 1).

œ

The engine-ECU (terminal No. 6) makes the
power transistor in the unit be in "ON", and that
makes currents go on the EGR control solenoid
valve (terminal No. 2).
