Repair or replace the connector.

STEP 13. Check harness between A-43 (terminal 
No. 1) camshaft position sensor connector and 
C-105 (terminal No. 90) engine-ECU connector.

NOTE: Before checking harness, check intermediate 
connector A-131, and repair if necessary.

STEP 14. Perform output wave pattern 
measurement at A-43 camshaft position sensor 
(Using an oscilloscope).

• Use special tool test harness (MB991709) to con-

nect connector, and measure at pick-up harness.

• Engine: Idling

• Transmission: Neutral <M/T> or P range <A/T>

• Voltage between terminal No. 2 and earth.

OK: Waveforms should be displayed on 
Inspection procedure using an oscilloscope 
(Refer to 

P.13A-586

), its maximum value 

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

Q: Is the check result normal?

YES : 

Go to Step 7 .

NO : 

Replace the camshaft position sensor.

Code No. P0341: Camshaft Position Sensor Range/Performance Problem

OPERATION

• Refer to Code No. P0340: Camshaft Position 

Sensor System 

P.13A-192

.

FUNCTION

• The camshaft position sensor detects the top 

dead center on the compression stroke of the No. 
1 cylinder and inputs a pulse signal to the engine-
ECU.

TROUBLE JUDGMENT

Check Conditions

• Battery positive voltage is 6 − 16 V.

• Engine speed is 350 r/min or more.

Judgment Criterion

• The number of output pulses from the camshaft 

position sensor every two engine rotations (from 
when one excessive tooth is detected to when 
another is detected) is not five.

PROBABLE CAUSES

• Failed camshaft position sensor

• Open/short circuit in camshaft position sensor cir-

cuit or loose connector contact

• Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Installation check of camshaft position 
sensor

• Check whether the camshaft position sensor is 

correctly installed.

Q: Is the check result normal?

YES : 

Go to Step 2 .

NO : 

Repair or replace the camshaft position 
sensor.

STEP 2. M.U.T.-III diagnosis code

• Reconfirmation of diagnosis code.

Q: Is the diagnosis code set?

YES : 

Replace the engine-ECU. When the engine-

ECU is replaced, write the chassis number 
(Refer to GROUP 00 

− Precautions Before 

Service 

− How to Perform Chassis Number 

Writing ). After replacing the engine-ECU, 
register the injector identification code and 
learn fuel injection (Refer to GROUP 00 

− 

Precautions Before Service 

− What The 

Common Rail Engine Learns ). After 
registering the injector identification code, 
the vehicle equipped with the DPF carries 
out the forcible DPF regeneration. (Refer to 
GROUP 17 

− Emission Control − Diesel 

Particulate Filter (DPF) System 

− Forcible 

DPF Regeneration ).

NO : 

Intermittent malfunction (Refer to GROUP 
00 

− How to Use Troubleshooting/

Inspection Service Points 

− How to Cope 

with Intermittent Malfunctions ).
