2ZR-FE ENGINE CONTROL SFI SYSTEM P0365 Camshaft Position Sensor "B" Circuit (Bank 1) P0367 Camshaft Position Sensor "B" Circuit Low Input (Bank 1) P0368 Camshaft Position Sensor "B" Circuit High Input (Bank 1)
DESCRIPTION
The camshaft position sensor (for exhaust camshaft) (EV1 signal) consists of a magnet and MRE (Magneto Resistance 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, which affects the magnetic field. 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, fuel injection timing and Variable Valve Timing (VVT) system.

MONITOR DESCRIPTION
If no pulse signal is transmitted by the camshaft position sensor (for exhaust camshaft) despite the camshaft rotating, the ECM interprets this as a malfunction of the sensor.
Also, when the sensor output voltage remains at less than 0.3 V, or higher than 4.7 V for 4 seconds, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Start the engine.
Idle the engine for 10 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read the pending DTCs.
- HINT:
- ·
If a pending DTC is output, the system is malfunctioning.
·If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
Input the DTC: P0365, P0367 or P0368.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL | ·
DTC judgment completed ·
System normal |
| ABNORMAL | ·
DTC judgment completed ·
System abnormal |
| INCOMPLETE | ·
DTC judgment not completed ·
Perform driving pattern after confirming DTC enabling conditions |
| N/A | ·
Unable to perform DTC judgment ·
Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit |
- HINT:
- ·
If the judgment result shows NORMAL, the system is normal.
·If the judgment result shows ABNORMAL, the system has a malfunction.
·If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT
- HINT:
- ·
If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
·Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
