Code P1325 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 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 determines that the VVA Solenoid switch on time cannot be measured a fault is set.
What are the Possible Causes of the DTC P1325 Jeep?
- 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

Frequently Asked Questions about P1325 Jeep Code
1. What does the OBDII code P1325 mean on a Jeep?
P1325 indicates that the Cylinder 3 Oil Supply Solenoid Valve Switch ON time is immeasurable, usually pointing to an issue with the Variable Valve Timing (VVT) system in the engine.
2. What are the common symptoms of the P1325 code on a Jeep?
Symptoms may include rough idling, reduced engine performance, poor fuel economy, hesitation during acceleration, or the Check Engine Light being illuminated.
3. What causes the P1325 code to appear on a Jeep?
Common causes include a faulty oil control solenoid, low engine oil pressure, dirty or degraded engine oil, a clogged oil passage, or an electrical issue such as damaged wiring or a bad connector.
4. Can low engine oil cause the P1325 code?
Yes, low or dirty engine oil can result in insufficient oil flow to the solenoid, causing the P1325 code to trigger.
5. How can I diagnose the P1325 code on my Jeep?
Start by checking the engine oil level and condition, inspect the wiring and connectors for damage, and test the oil control solenoid for proper operation.
6. How do I fix the P1325 code on a Jeep?
Repairs may include replacing the oil control solenoid, performing an oil and filter change, cleaning clogged oil passages, or repairing damaged wiring or connectors.
7. Is it safe to drive with the P1325 code active on my Jeep?
Driving with the P1325 code is not recommended, as it can lead to engine performance issues or further damage to the VVT system.
8. How much does it cost to repair the P1325 code on a Jeep?
The cost depends on the specific repair needed, but replacing an oil control solenoid typically ranges from $150 to $300, including parts and labor.
9. Will clearing the P1325 code solve the problem permanently?
Clearing the code without addressing the root cause will only temporarily turn off the Check Engine Light, and the issue is likely to return.
10. Can a bad oil control solenoid cause other engine issues?
Yes, a faulty oil control solenoid can disrupt the timing of the engine’s valves, leading to poor performance, reduced fuel economy, and potential long-term engine damage.
