DESCRIPTION

The exhaust camshaft Variable Valve Timing (VVT) sensor (EV1, 2 signal) consists of a magnet and MRE (Magnetic Resistance Element).


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.

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).

  • 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.
