Code P1047 Chrysler 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.

Frequently Asked Questions about P1047 Chrysler Code
What does OBDII code P1047 mean for a Chrysler vehicle?
Code P1047 indicates that the voltage for the Cylinder 2 Oil Supply Solenoid Valve is out of range, meaning the engine control module (ECM) has detected an issue with the circuit.
What are the common symptoms of code P1047?
Symptoms may include a check engine light, reduced engine performance, rough idling, misfires, or poor fuel economy.
What causes the P1047 code to appear?
Common causes include a faulty oil supply solenoid valve, damaged or corroded wiring, a bad electrical connection, or a malfunctioning ECM.
Can I continue driving with the P1047 code?
While the vehicle may still be drivable, ignoring the code could lead to further engine damage or decreased performance. It’s best to address the issue promptly.
How is the P1047 code diagnosed?
A technician will use a scan tool to verify the code, inspect the wiring and connectors, test the oil supply solenoid valve, and check for proper voltage and resistance in the circuit.
How do you fix the P1047 code on a Chrysler?
Repairs may involve replacing the faulty oil supply solenoid valve, repairing damaged wiring or connectors, or, in rare cases, replacing the ECM.
What tools are needed to troubleshoot a P1047 code?
Tools typically include a scan tool or OBDII scanner, a multimeter, and possibly an oscilloscope for advanced diagnostics.
Can low oil levels cause the P1047 code?
Yes, insufficient engine oil can lead to improper operation of the oil supply solenoid valve, potentially triggering the code.
How much does it cost to fix a P1047 code?
Repair costs vary but may range from $100 to $500, depending on whether the issue is with the solenoid valve, wiring, or ECM.
What preventive maintenance can help avoid the P1047 code?
Regular oil changes, maintaining correct oil levels, and inspecting electrical connections and wiring can help prevent this code from occurring.
