Q: How to Perform a CKP Pattern Clear/CKP Pattern Learn Procedure on Honda Crosstour?
A: Raise the vehicle, disconnect the electrical connector from the CKP sensor, and remove the sensor. Install a new O-ring. Start the engine and run it at 3000 rpm until the fan comes on. Drive and accelerate to 2500 rpm, then coast to 1000 rpm. Accelerate to 5000 rpm, then coast to 3000 rpm. Repeat this several times. Park, switch the ignition switch off and on and wait for 30 seconds. If the Check Engine light comes on or there are problems, perform the CKP Pattern Clear/CKP Pattern Learn procedure.
