Toyota Corolla (E120): Circuit description
The park/neutral position switch detects the shift lever position and sends signals to the ecm.

Monitor description
The park/neutral position switch detects the gearshift position and sends a signal to the ecm.
For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in p or n shift position.
When the park/neutral position switch sends more than one signal at a time from switch positions p, r, n, 2, or l the ecm interprets this as a fault in the switch. The ecm will turn on the mil.
