2AR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0365,P0367,P0368: Camshaft Position Sensor "B" Circuit (Bank 1)


DESCRIPTION

The camshaft position sensor for the exhaust camshaft (EV signal sensor) consists of a magnet and MRE element.

The exhaust camshaft has a timing rotor for the camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE element, which affects the magnet. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM. Then the ECM uses this data to control fuel injection duration, injection timing and the Variable Valve Timing (VVT) system.





HINT
DTC P0365, P0367 and P0368 indicate a malfunction relating to the exhaust camshaft position sensor circuit (the wire harness between the ECM and exhaust camshaft position sensor, and the exhaust camshaft position sensor itself).

Reference: Inspection using an oscilloscope P0335

MONITOR DESCRIPTION

If no signal is transmitted by the exhaust camshaft position sensor despite the camshaft revolving, or the rotation of the exhaust camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor.

If the malfunction is not repaired successfully, the DTC is stored 10 seconds after the engine is next started.

COMPONENT OPERATING RANGE





CONFIRMATION DRIVING PATTERN





1. Connect the Techstream to the DLC3.

2. Turn the ignition switch to ON and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Reading and Clearing Diagnostic Trouble Codes.

4. Turn the ignition switch off and wait for at least 30 seconds.

5. Turn the ignition switch to ON and turn the Techstream on [A].

6. Start the engine.

7. Idle the engine for 10 seconds or more [B].

8. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

9. Input the DTC: P0365, P0367 or P0368.

10. Check the DTC judgment result [C].





HINT
* If the judgment result shows ABNORMAL, the system has a malfunction.
* If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [B] and [C] again.

11. If the test result is UNKNOWN, enter the following menus: Powertrain / Engine / Trouble Codes / Pending.

12. Read the Pending DTCs.

HINT
If a pending DTC is output, the system is malfunctioning.

13. If the test result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
* If a permanent DTC is output, the system is malfunctioning.
* If no permanent DTC is output, the system is normal.

WIRING DIAGRAM

Refer to DTC P0335 P0335.

INSPECTION PROCEDURE

HINT
* Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
* If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.

PROCEDURE

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0365, P0367 OR P0368)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Trouble Codes.

(e) Read the DTCs.

Result:





HINT
If any DTCs other than P0365, P0367 or P0368 are output, troubleshoot those DTCs first.

B -- GO TO DTC CHART SFI System
A -- Continue to next step.

2. INSPECT CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT POWER SOURCE)

(a) Disconnect the camshaft position sensor (for exhaust camshaft) connector.





(b) Turn the ignition switch to ON.

(c) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





(d) Reconnect the camshaft position sensor (for exhaust camshaft) connector.

NG -- CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)

(a) Disconnect the camshaft position sensor (for exhaust camshaft) connector.

(b) Disconnect the ECM connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance (Check for Open):





Standard Resistance (Check for Short):





(d) Reconnect the camshaft position sensor (for exhaust camshaft) connector.

(e) Reconnect the ECM connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK SENSOR INSTALLATION (CAMSHAFT POSITION SENSOR FOR EXHAUST CAMSHAFT)

(a) Check the camshaft position sensor (for exhaust camshaft) installation.





OK:

Sensor is installed correctly.

NG -- SECURELY REINSTALL SENSOR Installation
OK -- Continue to next step.

5. INSPECT EXHAUST CAMSHAFT (TIMING ROTOR)

(a) Check the timing rotor of the exhaust camshaft.

OK:

Camshaft timing rotor does not have any cracks or deformation.

NG -- REPLACE EXHAUST CAMSHAFT Removal
OK -- Continue to next step.

6. CHECK VALVE TIMING

(a) Check the valve timing P0011.

NG -- ADJUST VALVE TIMING Removal
OK -- Continue to next step.

7. REPLACE CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT)

(a) Replace the camshaft position sensor Removal.

NEXT -- Continue to next step.

8. CHECK WHETHER DTC OUTPUT RECURS (DTC P0365, P0367 OR P0368)

(a) Connect the Techstream to the DLC3.
