DESCRIPTION

The VVT sensor (G signal) consists of a magnet and MRE element.

The exhaust camshaft has 3 teeth on its inner circumference. When the camshaft gear rotates, the air gap changes between the protrusion on the gear and the pickup coil. The change affects the magnetic field, resulting in a change in the resistance of the MRE element. The crankshaft angle sensor plate has 34 teeth and outputs 34 signals every engine revolution. The ECM detects the standard crankshaft angle based on the G signal, actual crankshaft angle and engine speed by an NE signal.

INSPECTION PROCEDURE

Tip:

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.
