RPM Signal

On all models except Supra Turbo, crankshaft position and engine RPM are detected by pick-up coils in the distributor. The ECU uses this information for controlling engine operation.

On all models except Tercel, Pickup 2.4L and 4Runner 2.4L, crankshaft position input signal is delivered to terminal G, G+ or G1 (and G2 on some models) of ECU and engine RPM input signal is delivered to terminal NE or NE+ of ECU.

Tercel, Pickup 2.4L and 4Runner 2.4L use a single pick-up coil and input signal is delivered to terminal NE of ECU.

On Supra Turbo, crankshaft position and engine RPM are detected by camshaft position sensor. Crankshaft position input signal is delivered to terminals G1 and G2 of ECU and engine RPM input signal is delivered to terminal NE of ECU.
