| DTC Code | DTC Name |
|---|---|
| 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 the exhaust camshaft (EV signal sensor) consists of a magnet and an MRE (Magneto Resistive 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 affect 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, and uses the pulse signals to determine the camshaft angle, which it sends to the ECM. Then the ECM uses this data to control fuel injection duration, injection timing and the Variable Valve Timing (VVT) system.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0365*1 | Missing exhaust camshaft position sensor signal for 5 seconds at engine speed of 600 rpm or more (1 trip detection logic) |
|
| P0367 | Output voltage of exhaust camshaft position sensor is below 0.3 V for 4 seconds (1 trip detection logic) |
|
| P0368 | Output voltage of exhaust camshaft position sensor is higher than 4.7 V for 4 seconds (1 trip detection logic) |
|
*1: w/ Stop and Start System
When the engine is stopped due to Stop and Start system control, the camshaft position sensor does not monitor, but will resume monitoring when the engine is running.
Tech Tips
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 Click here.
MONITOR DESCRIPTION
If no signal is transmitted by the camshaft position sensor despite the engine running, or the rotations of the camshaft and crankshaft are not synchronized, the ECM interprets this as a malfunction of the sensor.
Also, when the sensor output voltage remains below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a DTC.

| Required Sensors/Components (Related) | Crankshaft position sensor |
| Frequency of Operation | Continuous |
CONFIRMATION DRIVING PATTERN
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation)
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the tester on.
Idle the engine for 10 seconds or more.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read pending DTCs.
Tech Tips
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.
| Tester Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |
|
Tech Tips
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 the DTC judgment result again.

CAUTION / NOTICE / HINT
Tech Tips
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. 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.
If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
