Code P1033 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 PCM recognizes an internal problem with the Solenoid Signal or Return circuit.

Frequently Asked Questions about P1033 Jeep Code
1. What does the OBDII code P1033 mean for a Jeep?
The P1033 code indicates that the Cylinder 3 Oil Supply Solenoid Valve Driver Voltage is implausible, meaning there’s an issue with the electrical signal or operation of the solenoid valve responsible for controlling oil flow to cylinder 3.
2. What are the common symptoms of code P1033 in a Jeep?
Symptoms may include engine misfires, reduced performance, rough idling, poor fuel efficiency, or the Check Engine Light turning on.
3. What causes the P1033 code to appear on a Jeep?
Common causes include a faulty oil supply solenoid valve, wiring issues such as damaged or corroded connectors, low engine oil level or pressure, or a malfunctioning PCM (Powertrain Control Module).
4. Is it safe to drive a Jeep with the P1033 code?
Driving with this code may lead to further engine issues if oil flow is disrupted or cylinder performance is impaired. It’s recommended to address the issue promptly.
5. How can I diagnose the P1033 code on a Jeep?
Start by checking the oil level and condition, inspecting the wiring and connectors for damage, testing the oil solenoid valve for proper operation, and using a scan tool to monitor voltage signals.
6. Can low engine oil cause the P1033 code on a Jeep?
Yes, low or dirty engine oil can disrupt the oil supply to the solenoid, triggering the P1033 code.
7. How is the Cylinder 3 Oil Supply Solenoid Valve repaired for code P1033?
Repairs may involve replacing the oil supply solenoid valve, fixing damaged wiring or connectors, performing an oil change, or reprogramming or replacing the PCM if needed.
8. How much does it cost to fix the P1033 code on a Jeep?
Repair costs can vary, but replacing the solenoid valve typically costs between $100-$300, while wiring repairs or PCM replacement may cost more depending on labor and parts.
9. Can I clear the P1033 code without fixing the issue?
Clearing the code without addressing the underlying problem may temporarily turn off the Check Engine Light, but the issue will likely return and could lead to further damage.
10. How does the PCM contribute to the P1033 code on a Jeep?
The PCM monitors the voltage signal from the oil supply solenoid valve. If the signal is outside expected parameters, the PCM triggers the P1033 code. A faulty PCM may also cause this issue.
