Code P1445 Description
The P1445 code indicates a Purge Flow Sensor Circuit High Condition. This means that the engine control module (ECM) has detected a high voltage signal from the purge flow sensor circuit, which monitors the flow of fuel vapor from the charcoal canister to the engine intake manifold. This system is part of the vehicle's evaporative emission control system, which helps to reduce harmful emissions by capturing and burning fuel vapors before they can escape into the atmosphere.
Common Causes of P1445
- Faulty purge flow sensor
- Damaged or corroded wiring in the sensor circuit
- Vacuum leaks in the evaporative emission control system
- Clogged charcoal canister
- ECM software issue
Symptoms of P1445
- Check engine light illuminated on the dashboard
- Poor fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Strong fuel odor from the vehicle
How to Fix P1445
- Diagnose the issue using a scan tool to verify the P1445 code and identify the specific cause of the high voltage signal.
- Inspect the purge flow sensor and its wiring for any damage or corrosion. Replace the sensor if faulty and repair or replace any damaged wiring.
- Check the charcoal canister and purge valve for proper operation. Clean or replace these components as needed.
- Inspect the vacuum lines in the evaporative emission control system for leaks or blockages. Repair or replace any damaged lines.
- Clear the code from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1445
The typical repair costs for resolving a P1445 code can vary depending on the specific cause of the issue and the labor rates in your area. In general, you can expect to pay between $100 and $300 for parts and labor to address this problem. It's important to consider the diagnosis time and labor rates at your local auto repair shop, as well as any additional components that may need to be replaced during the repair process. Be sure to obtain a detailed estimate from a qualified mechanic before proceeding with the repair.
