T100 Pickup 4WD V6-180.5 2959cc 3.0L SOHC (3VZ-E) (1993)
Pick-Up Coil: Description and Operation
PURPOSE
The NE Pickup Coil, though separate, works in conjunction with the G1 and G2 Pickup Coils and produces an output pulse to the Engine Control
Module (ECM). The ECM uses this signal to determine engine speed and relative top dead center for each cylinder.
OPERATION
The NE Coil detects the crankshaft position. Whenever the engine is rotating, a sine-wave signal is returned to the ECM. As engine speed
increases the frequency of the signal increases as well. When coupled with the signal of the G1 and G2 Pickup Coils, exact piston position can be
determined by the ECM.
