Code P1065 Fiat Description
The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The VVA Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting the lift and duration of the valve opening.
The Diagnostic Trouble Code (DTC) will be set when the PCM measures the time needed to turn on the VVA Solenoid. When the PCM recognizes that the VVA Solenoids switch on time is too fast or too slow a fault is set.

- Engine oil level low
- Engine oil contaminated
- Incorrect oil filter
- Insufficient oil pressure due to a mechanical failure in the oiling system
- Faulty Variable Valve Actuator (VVA) Assembly
