Camshaft Position Sensor "B" Circuit (Bank 1)
|
DESCRIPTION
The cam position sensor for the exhaust camshaft (EV1 signal) consists of a magnet and MRE (Magneto Resistive Element).
The exhaust camshaft has a timing rotor for the cam position sensor. When the exhaust 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 cam 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 and fuel injection timing.
DTC No.

MONITOR DESCRIPTION
If no pulse signal is transmitted by the cam position sensor (for exhaust camshaft) despite the camshaft rotating, the ECM interprets this as a malfunction of the sensor.

CONFIRMATION DRIVING PATTERN
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the Techstream 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.
-
Turn the Techstream 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.
-
Check the DTC judgment result.

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 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 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.
