How do I relearn a crank sensor without a scanner?

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.

How do you crank relearn?

Crank Relearn Procedure

1. Run the engine until the vehicle reaches normal operating temperature (ECT > ~65C or 150F).
2. Put the vehicle into Park (auto) or Neutral (manual).
3. Turn off all accessories including the A/C, heater, and fans.
4. Turn the vehicle off.
5. Apply the parking brake.
6. Press the brake pedal.

How do you relearn a crankshaft sensor without a scanner?

What is code p1336?

The code that you are referring to typically means there is an electrical problem in the crankshaft position sensor circuit. Once you drive the vehicle the ECM automatically integrates the output of the sensor. You can try erasing the code and driving the car to see if the Check Engine Light stays off.

What scan tool can do a case relearn?

The CASE Relearn can be done by anyone with a Tech 2 scan tool, advanced snap-on scanner, or also a Dashhawk or Aeroforce Scan Gauge depending on the vehicle.

What is the crankshaft position sensor relearn procedure?

The PCM needs to learn the variability of the Crankshaft Position Sensor to better detect misfire conditions. Whenever the PCM is replaced, the Crankshaft Position Sensor Relearn procedure needs to be completed. The Crankshaft Position Sensor Relearn procedure requires the use of a scan tool that has this feature equipped.

What happens when you replace the crank sensor on a car?

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. The proper procedure for resyncing or relearning the crankshaft position is called the “CKP Variation Learn.”

How do you reset the crankshaft position?

The proper procedure for resyncing or relearning the crankshaft position is called the “CKP Variation Learn.” The CKP Variation Learn procedure resets the positional information in the PCM’s memory and replaces it with updated information from the new crankshaft sensor. Step 1

Does the crankshaft sensor have to be synced to the PCM?

by Kyle Sanstrom 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.
