Power is supplied to the crank angle sensor (terminal
No. 3) from the engine control relay (terminal No. 4) and is earthed to the engine-ECU (terminal
No. 28) from the crank angle sensor (terminal No. 1).
A power voltage of 5 V is applied to the crank angle sensor output terminal (terminal
No. 2) from the engine-ECU (terminal No. 13).
The crank angle sensor detects the crank angle (position)
and inputs a pulse signal to the engine-ECU.
In response to the signal, the engine-ECU controls the injector, etc.
While engine is being cranked.
Crank angle sensor output voltage has not been changed (no pulse signal has been
input) for 2 seconds.
Failed crank angle sensor
Open or shorted crank angle sensor circuit, harness damage, or connector damage
