The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference. When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which affects the magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor converts the exhaust camshaft rotation data into pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM.

DTC Code	DTC Detection Condition	Trouble Area
P0365 P0390	When either condition below is met: The input voltage to the ECM remains at below 0.3 V or higher than 4.7 V for more than 4 seconds when 2 or more seconds have elapsed after turning the engine switch on (IG) (1 trip detection logic). No VVT sensor signal is sent to the ECM during cranking (1 trip detection logic).

Standard:

Tester Connection	Tool Setting	Condition	Specified Condition
C45-110 (NE+) - C45-111 (NE-)	5 V/DIV. 20 msec./DIV.	Cranking or idling	The correct waveform is as shown
C45-69 (EV1+) - C45-68 (EV1-)	5 V/DIV. 20 msec./DIV.	Cranking or idling	The correct waveform is as shown
C45-64 (EV2+) - C45-65 (EV2-)	5 V/DIV. 20 msec./DIV.	Cranking or idling	The correct waveform is as shown

HINT:

EV1+ and EV2+ stand for the VVT sensor (for exhaust side) signal, and NE+ stands for the CKP sensor signal.

MONITOR DESCRIPTION

If no signal is transmitted by the VVT sensor despite the engine revolving, or the rotations of the camshaft and the crankshaft are not synchronized, the ECM interprets this as a malfunction of the sensor.

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition 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.

Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.

Bank 2 refers to the bank that does not include the No. 1 cylinder.

1.CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE)

Disconnect the C121 or C122 VVT sensor (for exhaust side) connector.

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

Standard Voltage:
Tester Connection Condition Specified Condition
C121-3 (VC2) - Body ground Engine switch on (IG) 4.5 to 5.0 V
C122-3 (VC2) - Body ground Engine switch on (IG) 4.5 to 5.0 V

REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

2.CHECK HARNESS AND CONNECTOR (VVT SENSOR (for Exhaust Side) - ECM)

Disconnect the C121 or C122 VVT (for exhaust side) sensor connector.

Disconnect the C45 ECM connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
C121-1 (EX+) - C45-69 (EV1+)	Always	Below 1 Ω
C121-2 (EX-) - C45-68 (EV1-)	Always	Below 1 Ω
C122-1 (EX+) - C45-64 (EV2+)	Always	Below 1 Ω
C122-2 (EX-) - C45-65 (EV2-)	Always	Below 1 Ω
C121-1 (EX+) or C45-69 (EV1+) - Body ground	Always	10 kΩ or higher
C121-2 (EX-) or C45-68 (EV1-) - Body ground	Always	10 kΩ or higher
C122-1 (EX+) or C45-64 (EV2+) - Body ground	Always	10 kΩ or higher
C122-2 (EX-) or C45-65 (EV2-) - Body ground	Always	10 kΩ or higher

6.CHECK WHETHER DTC OUTPUT RECURS

Connect the intelligent tester to the DLC3.

Turn the engine switch on (IG).

Turn the tester on.

Clear DTCs ().

Start the engine.

Enter the following menus: Powertrain / Engine and ECT / DTC.

Read DTCs.
