How many ohms should a crank sensor have?

The readout should indicate a resistance value, usually between 200 and 2000 ohms, depending on your particular vehicle model. Compare your results to the manufacturer specifications. You may find the specification in your vehicle repair manual. If out of specification, replace the sensor.

How do you calibrate a crank sensor?

1. Turn off all of the accessories.
2. Accelerate the vehicle to 55 mph at part throttle.
3. Cruise at 55 mph for another 5-6 minutes.
4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary.

What is a crank relearn?

A crank relearn is a process that the PCM goes through to recalibrate its knowledge of the relationship between the crankshaft and camshaft. That’s necessary because the crank and cam are connected by a timing chain or timing belt.

What kind of power does the LS1 crank sensor use?

I don’t know why they say this, as they use 12 volt on the LS1 instead of the 5 volt power, but the sensors are good from 5 to 36 volts. We have ran 12 volts on 58x all the way back to 2006, and never had one issue with it.

Where is the crankshaft position ( CKP ) sensor located?

Circuit Description. The Crankshaft Position Sensor CKP is mounted in the right rear of the engine block behind the starter. The CKP sensor works in conjunction with a 24X reluctor wheel mounted on the rear of the crankshaft.

Where is the LS1 sensor located on a GM car?

This sensor is mounted at the rear of the engine and thorough the top of the engine block – GM Part Number 12561211. This sensor provides the PCM with the data needed to determine engine speed and one of the main factors used to calculate injector pulse width (IPW) and ignition timing.

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.
