What does it mean?
P1445 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Purge Flow Sensor Circuit High Input .
Evaporative Emission (EVAP) System Flow During Non-Purge Chevrolet Only
Severity
Low
Can I keep driving?
Usually drivable; have it fixed at the first opportunity.
First step
A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Identify the manufacturer-specific interpretation for your make and year 2. Inspect the EVAP system for visible damage: cracked hoses, loose clamps, missing fuel cap seal 3. Test the vent valve electrically and operationally; a hand vacuum pump (£20) helps verify it holds and releases vacuum correctly 4. Read live fuel tank pressure data with a scan tool 5. Workshop smoke test of the EVAP system (£30-£60) finds leaks reliably 6. Check the fuel cap seal for cracks; old or damaged caps are a cheap first try
