The crankshaft position (CKP) sensor monitors the position or rotational speed of the crankshaft. If the crankshaft position sensor has failed completely, and isn’t sending a signal to the (ECU) at all, then the computer won’t send any fuel to the injectors. This will leave you unable to start the car.
If there’s no spark or the spark is weak, check the resistance of the wire that connects the ignition coil to the distributor cap. Consult the wire resistance specifications in your repair manual.
If there’s no voltage, check the wire between the ignition switch and the coil and, if necessary, the switch itself. If there’s voltage, the problem may be with the pickup unit. If the pickup is good, then the problem may be with the ignition control module.
How does spark generation work in an ignition system?
Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor. The ignition module uses the information to time spark generation.
