DESCRIPTION

DTC Detection Condition:

The exhaust camshaft's Variable Valve Timing (VVT) sensor consists of a magnet and MRE (Magneto 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 to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds (Part 1):

Typical Malfunction Thresholds (Part 2):

If no signal is transmitted by the VVT (for exhaust camshaft) sensor despite the engine revolving, or the rotations of the exhaust 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. 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.
