CKP Pattern Learn Procedure

NOTE: Enable criteria: Engine coolant temperature must be 176°F (80°C) or higher.
  1. Having cleared the CKP pattern from PCM, leave Honda PGM Tester or the HDS connected to DLC and turn ignition switch off. Turn ignition switch on. Wait for 30 seconds.
  2. Start vehicle and test drive on a level road. Decelerate (with throttle fully closed) from engine speed of 2500 RPM to 1000 RPM with A/T in "2" or "D3" position.
  3. Stop vehicle. DO NOT turn the ignition switch off. Select the ALL DATA list in DATA LIST menu using Honda PGM Tester or the HDS .
  4. Check status of PULSER F/B LEARN. If it is set to NG, enable criteria was probably not met; repeat the procedure from beginning.
