1. Disconnect the variable valve lift control motor connector.
2. Measure the resistance between the terminals of the connector at the variable valve lift control motor.Standard value:|   | | Tester connection terminal | Normal condition |  | 11 - 12 | Continuity |  | 12 - 13 |  | 11 - 13 |  
  | 
| Tester connection terminal | Normal condition | 
| 11 - 12 | Continuity | 
| 12 - 13 | 
| 11 - 13 | 
 | note | Substantially small resistance valve {36 to 125 mΩ [at 20°C (68°F)]} is displayed, but it is normal as long as continuity exists. | 
 3. If the resistance deviates from the standard value, replace variable valve lift control motor.
