A bad coil on a k21-k25 can cause a crankshaft sensor code. You can start the engine and disconnect 3 of the coils to determine which coil is bad. Then connect another coil and disconnect the one previously connected. Keep going till it has run on each cylinder by itself. These engines will run on 1 cylinder. The bad one will kill the motor when it tries to run it by itself.
