Code P0459 Chrysler Description
The P0459 Chrysler code refers to a problem with the evaporative emission purge solenoid control circuit having high voltage. This component is part of the vehicle's evaporative emissions system, which is responsible for controlling the release of harmful gasoline vapors into the atmosphere. The purge solenoid is a vital part of this system, as it regulates the flow of fuel vapor from the charcoal canister to the engine for combustion. When the control circuit has high voltage, it indicates that there is an issue with the electrical connection or the solenoid itself, which can lead to improper functioning of the evaporative emissions system.
Common Causes of P0459 Chrysler
- Faulty evaporative emission purge solenoid
- Wiring or electrical connection issues
- Corrosion or damage to the solenoid
- Vacuum leaks in the system
- ECM (Engine Control Module) malfunction
Symptoms of P0459 Chrysler
- Check Engine Light is illuminated
- Rough idling or stalling
- Decreased fuel efficiency
- Strong gasoline odor
- Failed emissions test
How to Fix P0459 Chrysler
- Begin by diagnosing the issue using a scan tool to confirm the P0459 code.
- Inspect the wiring and electrical connections to the evaporative emission purge solenoid for any damage or corrosion.
- Test the solenoid itself to determine if it is functioning properly or needs to be replaced.
- Check for vacuum leaks in the system and repair as necessary.
- If the ECM is suspected to be the cause, further diagnostic testing may be required to confirm and replace if needed.
Cost to Fix P0459 Chrysler
The cost of repairing a P0459 Chrysler code can vary depending on the specific cause of the issue. On average, the repair may cost between $100 to $300 for parts and labor. However, it's important to note that prices can be higher or lower based on the location, vehicle make and model, and the hourly labor rates of the repair shop. It's recommended to obtain quotes from different shops to get a more accurate estimate.

What are the common symptoms of code P0459 in Chrysler vehicles?
Symptoms may include a check engine light, decreased fuel efficiency, rough idling, or difficulty starting the engine.
What causes the P0459 code to appear on a Chrysler?
Common causes include a faulty purge solenoid, damaged wiring or connections, electrical short circuits, or issues with the PCM.
Can driving with code P0459 damage my Chrysler?
Typically, P0459 doesn’t cause immediate damage, but ignoring it can lead to increased emissions or potential long-term engine issues.
How do I diagnose code P0459 on my Chrysler?
Start by inspecting the wiring and connectors near the purge solenoid for damage, then test the solenoid itself and check for proper voltage in the circuit.
How do I fix the P0459 code on a Chrysler?
Repairs may involve replacing the purge solenoid, fixing damaged wiring, or addressing faults in the PCM if necessary.
Can a loose gas cap trigger code P0459 in a Chrysler?
No, a loose gas cap usually triggers codes related to the EVAP system leak, such as P0440 or P0456, not P0459.
How much does it cost to fix code P0459 in a Chrysler?
Repair costs vary but may range from $50 to $300, depending on whether the purge solenoid or wiring needs replacement.
Does a P0459 code affect vehicle performance?
It may cause minor performance issues like rough idling or starting problems, but it primarily affects the EVAP system.
Can I reset code P0459 without repairing the issue?
Clearing the code without fixing the underlying problem may temporarily turn off the check engine light, but the code will likely return.
