Code P106C 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 off time is too fast or too slow a fault is set.
What are the Possible Causes of the DTC P106C?
- 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
How to Fix the DTC P106C?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0

Symptoms may include engine misfires, reduced power, rough idling, increased oil consumption, and the Check Engine Light turning on.
What causes code P106C?
Possible causes include a faulty oil supply solenoid valve, oil contamination, wiring issues, or low oil pressure in the engine.
How can I diagnose code P106C?
Diagnosis involves checking the solenoid valve for proper operation, inspecting the wiring and connectors for damage, and verifying oil pressure and cleanliness.
Can low oil levels cause code P106C?
Yes, insufficient oil levels or contaminated oil can lead to solenoid valve issues and trigger this code.
How do you fix code P106C?
Repairs typically include replacing the faulty solenoid valve, cleaning or changing the oil, and repairing damaged wiring or connectors.
Is it safe to drive with code P106C?
Driving with this code is not recommended as it can lead to engine performance issues and potentially cause long-term damage.
How much does it cost to repair code P106C?
Repair costs vary but may range from $100 to $300 depending on whether the solenoid valve needs replacement or other repairs are required.
Can a dirty oil filter cause code P106C?
Yes, a clogged or dirty oil filter can restrict oil flow and contribute to issues with the solenoid valve operation.
Should I reset the code after repairs?
Yes, after completing repairs, use an OBDII scanner to clear the code and verify that it does not return.
