2Zr-Fe Engine Control. Dtc P0365 Camshaft Position Sensor B Circuit (Bank 1)

The camshaft position sensor for exhaust camshaft (EV signal) consists of a magnet and MRE.
The exhaust camshaft has a timing rotor for camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, 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, 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	No camshaft position sensor signal is sent to the ECM at an engine speed of 600 rpm or more. (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor Exhaust camshaft Jumped tooth of timing chain for exhaust camshaft ECM
P0367	Output voltage of exhaust camshaft position sensor less than 0.3 V for 4 seconds (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor ECM
P0368	Output voltage of exhaust camshaft position sensor more than 4.7 V for 4 seconds (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor ECM

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).

MONITOR DESCRIPTION

If no signal is transmitted by the exhaust camshaft position sensor despite the engine revolving, or the rotation of the exhaust camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor.
Also, when the sensor output voltage remains at less than 0.3 V, or more than 4.7 V for 4 seconds or more, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN

Connect the Techstream to the DLC3.
Turn the ignition switch to ON and turn the Techstream on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation) (COROLLA_ZRE142 RM000000PDK0ZAX.html).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the Techstream on.
Start the engine.
Idle the engine for 10 seconds or more [A].
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
Read the pending DTCs.
HINT:
1. If a pending DTC is output, the system is malfunctioning.
2. 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.

Techstream 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 steps [A] and [B] again.

If no pending DTC is output, perform a universal trip and check for permanent DTCs (COROLLA_ZRE142 RM000000PDK0ZAX.html).
HINT:
1. If a permanent DTC is output, the system is malfunctioning.
2. If no permanent DTC is output, the system is normal.

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, troubleshoot the engine mechanical system.
