DTC 0101

COMPONENT DESCRIPTION
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.






ECM TERMINALS AND REFERENCE VALUE
Specification data are reference values, and are measured between each terminal and (25) (ECCS ground).






ON BOARD DIAGNOSIS LOGIC


DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

NOTE:
- If both DTC P0340 (0101) and P1335 (0407), P0335 (0802) or P1336 (0905) are displayed, perform TROUBLE DIAGNOSIS FOR DTC P1335, P0335 or P1336 first.
- If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

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


Without Scan Tools
(1) Crank engine at least 2 seconds.
(2) Turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
(3) Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.

DIAGNOSTIC PROCEDURE


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 - 1,760 Ohms at 20°C (68°F)
(HITACHI make)
Approximately 2,090 - 2,550 Ohms at 20°C (68°F)
(MITSUBISHI make)
