WARNING: This page is about a different car, the 1989 Toyota Pickup, 1989 Toyota Camry, 1989 Toyota Cab & Chassis, and 1989 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

ECU will store trouble code No. 12 in memory if it does not receive signal from either "NE" pick-up coil (RPM) or "G" pick-up coil (crank position) within 2 seconds of engine cranking.
