How big should a crankshaft position sensor be?
It should range from 0.6 mm to 1.5 mm. In the absence of any problems, you can move on to finding hidden issues in the wiring diagram of the device. To measure the spinning resistance of the crankshaft sensor use an ohmmeter (multimeter). Properly functioning sensor will range from 550 to 750 ohms.
What happens to the crank sensor on a GMC?
The crankshaft sensor on GMC vehicles is synced to the powertrain control module, or PCM. When the crank sensor is replaced, it must be resynced to the PCM. Without resyncing, the PCM cannot properly determine the position of the crankshaft.

Can a bad crankshaft sensor cause engine to run rough?
You will feel, and maybe hear, this as a brief stutter in the engine. You might feel that the engine runs rough or vibrates at idle, say, when you’re sitting at a red light. This is similar to the above in that it stems from poor spark timing. As seen with rough idling, sometimes crankshaft position sensor problems are worse at low engine speeds.
How much does it cost to replace the crankshaft position sensor?
