Code 0101

The camshaft position sensor (PHASE) is located on the engine front cover facing the camshaft sprocket. It detects the cylinder No. signal.
The sensor consists of a permanent magnet, core and coil.
When engine is running, the gap between the sensor and the camshaft sprocket will periodically change. Permeability near the sensor also changes.
Due to the permeability change, the magnetic flux near the core is changed. Therefore, the voltage signal generated in the coil is changed.
The ECM receives the voltage signal and detects the cylinder No. signal.




DIAGNOSTIC CHART




DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

NOTE:
- If both DTC 0101 (P0340) and 0407 (P1335), 0802 (P0335) or 0905 (P1336) are displayed, perform TROUBLE DIAGNOSIS FOR DTC 0407, 0802 or 0905 first.

- Before performing the following procedure, confirm that battery voltage is more than 10.5V.

CONSULT
1) Turn ignition switch "ON" and select "DATA MONITOR" mode with
CONSULT.
2) Crank engine for at least 2 seconds.

OR

GST
1) Crank engine for at least 2 seconds.
2) Select "MODE 3" with GST.

OR

NO TOOLS
1) Crank engine for at least 2 seconds.
2) Turn ignition switch "OFF", wait for at least 5 seconds and then turn "ON".
3) Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.







COMPONENT INSPECTION
Camshaft position sensor (PHASE)
1. Disconnect camshaft position sensor (PHASE) harness connector.
2. Loosen the fixing bolt of the sensor.
3. Remove the sensor.
4. Visually check the sensor for chipping.
5. Check resistance as shown in the figure.

Resistance:
Approximately 1,440 - 1,760ohms at 20°C (68°F) (HITACHI make)
Approximately 2,090 - 2,550ohms at 20°C (68°F) (MITSUBISHI make)
