Fuel injector
CKP sensor (pickup coil) signal is produced,
but fuel injector signal is interrupted 4 times or
more continuously. In this case, the code C32
(P0201), C33 (P0202), C34 (P0203) or C35
(P0204) is indicated.
Primary fuel injector, wiring/
coupler connection, power
supply to the injector.
