DTC P1140 (RIGHT, -B1),INTAKE VALVE TIMING CONTROL POSITION SENSOR
Intake valve advance unit position sensors are located in the front cylinder heads in both right/left banks. This sensor uses a Hall IC (element). The cam position is determined by the intake primary cam sprocket concave (in three places). The ECM provides feedback to the intake valve timing control for appropriate target valve open-close timing according to drive conditions based on detected cam position.
common problem, the sensor is bad and needs to be replaced
depending on you mileage, it may be covered under warranty. the sensor is covered for 3 years or 36,000 miles
