What happens when the crank sensor goes bad?
When the crank sensor goes bad, your vehicle will crank but not start. If it starts, the crank sensor is working. TIP 4: You’ll notice that the image (of the crank sensor) in this test article show it out of the vehicle, this is just to make it easier to show you the wires to be tested. On your vehicle, DO NOT remove the crank sensor to test it.
How does the crank signal work on an ignition coil?
The engine starts to crank, inducing the crankshaft position sensor to start producing its crank signal. The crank signal upon being received by the PCM along with other necessary sensor information, starts to do its little song and dance and sends back a Triggering Signal to each ignition coil.
How to test the crank sensor no spark no start?
Locate the crank sensor and disconnect it from its connector. Now, remove some of the plastic wire loom protector and/or the black electrical tape that shields the three wires of the CKP sensor. Remove enough of this electrical tape insulation to gain comfortable access to the three wires it protects. Place the multimeter in Volts DC mode.
Where is the crank sensor on a car?
On your vehicle, DO NOT remove the crank sensor to test it. The crank sensor is located on the transmission bell housing (on the side facing the fire-wall) and it’s held in place by a bolt. To set up the test, you’ll need to unplug the crank sensor from its connector so that you can connect your multimeter’s red test lead to the crank signal wire.
What should the voltage be on the CKP sensor?
If the CKP sensor is working correctly, the multimeter will register an On/Off voltage of 5 Volts DC. On is when the multimeter displays 5 Volts DC and off is 0.5 Volts DC. The key to seeing this voltage change is to turn the crankshaft pulley slowly and steadily.

Why did my car not start after I replaced the sensor?
If you disconnected the battery before replacing the sensor, this could be one cause of the vehicle not to start. A new crankshaft sensor should not have prevented the vehicle from starting.
