P1480 · ChryslerPCV Solenoid Valve Open Or Shorted

Q: What does code P1480 mean?

PCV Solenoid Valve Open Or Shorted. P1480 on Chrysler vehicles means the powertrain control module (PCM) has detected an open circuit or a short to ground or power in the wiring for the positive crankcase ventilation (PCV) solenoid valve. The PCM commands the solenoid to open or close to regulate crankcase vapors, and it monitors the control circuit for expected voltage or current; when the feedback falls outside the expected range, it stores this code.

Symptoms you may notice

Illuminated check engine light, often with no other symptoms
Rough or unstable idle quality
Increased oil consumption or oil seepage from seals
A slight fuel odor or crankcase vapor smell
Possible hesitation or stumble during light acceleration
In rare cases, a whistling or hissing noise from the PCV area

Common causes, most likely first

Failed PCV solenoid valve (open or shorted internally)
Damaged, chafed, or disconnected wiring to the PCV solenoid
Corroded or loose electrical connector at the solenoid
Blown fuse or faulty relay supplying power to the solenoid circuit
PCM driver circuit failure (less common)
Aftermarket or incorrect solenoid installed that does not match PCM expectations

How to diagnose and fix it

Verify the code with a scan tool and check for any related PCV or EVAP codes
Inspect the PCV solenoid connector and wiring for damage, corrosion, or looseness
Measure resistance across the solenoid terminals and compare to factory specification
Check for battery voltage at the solenoid connector with the key on, engine off
Test the control circuit from the PCM to the solenoid for continuity and shorts to ground or power
Replace the PCV solenoid if electrically faulty, then clear the code and verify repair
If wiring and solenoid test good, diagnose the PCM driver circuit or replace the PCM as a last resort

PCV solenoid circuit checks before replacement

A stuck-open or stuck-closed PCV solenoid can set P1480 without any driveability complaint, so many owners replace the part unnecessarily when the real fault is a chafed wire near the intake manifold.
The PCV solenoid on Chrysler engines is often confused with the PCV valve itself; the valve is a mechanical check valve, while the solenoid is an electrically controlled valve that the PCM uses to meter crankcase flow.
Corrosion inside the solenoid connector pins is a frequent cause on older Chrysler vehicles, and simply cleaning the terminals with contact cleaner can resolve the code without parts.
A faulty ground for the solenoid circuit can mimic a short to power, so always verify the ground path before condemning the PCM.
After replacing the solenoid, some Chrysler PCMs require a relearn or key cycle before the monitor will run and clear the code, so do not assume the repair failed if the light stays on immediately.

Can I keep driving with P1480?

You can usually continue driving with P1480 because it rarely causes an immediate safety risk, but avoid ignoring it for long periods since a failed PCV solenoid can lead to oil consumption or seal damage. Have the circuit inspected soon, especially if you notice rough idle or oil leaks.
