Code P1047 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 Variable Valve Actuator (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 calculates that the delay in the measurement of current samples is greater that the required sampling period.
What are the Possible Causes of the DTC P1047?
- Faulty Variable Valve Actuator (VVA) Solenoid
- Variable Valve Actuator Solenoid harness is open or shorted
- Variable Valve Actuator Solenoid circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P1047?
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
To diagnose the P1047 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1047 Code
What does OBDII code P1047 mean?
Code P1047 indicates that the voltage for the Cylinder 2 Oil Supply Solenoid Valve is out of the expected range, often signaling an electrical or mechanical issue related to oil flow management.
What are the common symptoms of code P1047?
Symptoms may include engine misfires, reduced performance, rough idling, poor fuel economy, or the check engine light illuminating.
What causes code P1047 to appear?
Common causes include a faulty oil supply solenoid valve, wiring issues such as shorts or open circuits, a damaged connector, or low engine oil levels affecting valve operation.
Can low oil levels trigger code P1047?
Yes, insufficient oil levels can disrupt the operation of the oil supply solenoid valve, potentially causing the voltage to fall out of range and setting this code.
How can I diagnose code P1047?
Start by checking the wiring and connectors for damage or corrosion, inspect the solenoid valve for faults, and verify engine oil levels and condition. Use a multimeter to test voltage and continuity.
How do I fix code P1047?
Repairs may involve replacing the faulty oil supply solenoid valve, repairing damaged wiring or connectors, topping off engine oil, or addressing underlying mechanical issues.
Can driving with code P1047 damage the engine?
Yes, ignoring this code can lead to improper oil flow to the cylinder, increasing wear and potentially damaging engine components over time.
What tools are needed to troubleshoot code P1047?
You may need an OBDII scanner, a multimeter for electrical testing, and basic hand tools for inspecting and replacing parts.
Is code P1047 specific to certain vehicle makes and models?
While the code itself is standardized, its occurrence may be more common in vehicles with advanced variable valve timing systems that rely on oil solenoids.
Can a dirty oil filter contribute to code P1047?
Yes, a clogged oil filter can restrict oil flow, impacting the solenoid's performance and triggering this error code.
