RPM Signal

On all models except Supra Turbo, crankshaft position and engine RPM are detected by pick-up coils in the distributor. On all models except 4-cylinder Pickup and 4Runner, and Tercel, crankshaft position is read by ECU at G1 terminal (and G2 on some models), and engine RPM is input to ECU terminal Ne.

On Pickup/4Runner (22R-E) and Tercel, a single pick-up coil is used in the distributor. ECU monitors pick-up coil signal at terminal Ne. On Supra Turbo models, crankshaft position and engine RPM are detected by the camshaft position sensor. Crankshaft position is input to ECU terminals G1 and G2, and engine RPM is input to terminal Ne.
