Mass Air Flow Meter
The 2GR-FE engine uses the same mass air flow meter as the 2AZ-FE engine. For details, see page EG-38.
Crankshaft Position Sensor
The timing rotor of the crankshaft consists of 34 teeth, with 2 teeth missing. The crankshaft position sensor
outputs the crankshaft rotation signals every 10
, and the missing teeth are used to determine the
top-dead-center.
