Code P1046 Jeep 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 Variable Valve Actuator (VVA) solenoid current feedback level in voltage is out of range.

What are the symptoms of the P1046 code on a Jeep?
Common symptoms include an illuminated check engine light, rough idling, reduced engine performance, misfires, or unusual engine noises.
What causes the P1046 code on a Jeep?
Possible causes include a faulty oil supply solenoid valve, damaged wiring or connectors in the solenoid circuit, low engine oil level, or a malfunctioning PCM.
Can I drive my Jeep with the P1046 code?
Driving with this code is not recommended, as it can lead to engine performance issues or potential damage if the problem is not addressed.
How do I diagnose the P1046 code on a Jeep?
Start by checking the oil level and quality, inspecting the solenoid valve wiring and connectors for damage, and testing the solenoid valve itself for proper operation.
What tools are needed to diagnose the P1046 code?
You’ll need an OBDII scanner, a multimeter for electrical tests, and basic tools for inspecting and possibly removing components.
How do I fix the P1046 code on a Jeep?
Repairs may involve replacing the faulty oil supply solenoid valve, repairing damaged wiring or connectors, performing an oil change, or in rare cases, reprogramming or replacing the PCM.
How much does it cost to fix the P1046 code on a Jeep?
Repair costs can vary but typically range from $100 to $300 depending on whether the solenoid valve, wiring, or other components need replacement.
Can low oil cause the P1046 code?
Yes, low or poor-quality oil can restrict proper operation of the oil supply solenoid valve, potentially triggering the P1046 code.
How can I prevent the P1046 code from appearing again?
Regularly check and maintain proper engine oil levels, use the recommended oil type, and inspect wiring and connectors during routine maintenance.
