P0443 on Honda by model: symptoms, diagnosis and fix
The EVAP canister purge control solenoid on the intake manifold sticks open, throwing evaporative-system codes — commonly P0496 (EVAP flow during a non-purge condition), P0441 (incorrect purge flow), or a large-leak P0455 — and causing rough idle, hard/rough starts right after refueling, and a faint fuel smell. A worn or non-OEM gas cap is the first thing to rule out for P0455; if a genuine cap doesn't clear it, the purge valve is the usual culprit. The under-car vent solenoid at the charcoal canister is a secondary leak source from corrosion.
Common Symptoms
- Check engine light P0496, P0441, P0443 or P0455
- Rough or hard start after refueling
- Rough idle or slight hesitation
- Faint fuel odor
- Failed emissions test
How to Fix
Confirm the gas cap seals (replace with a genuine Honda cap if in doubt). If codes persist, replace the canister purge control solenoid valve — verified OEM part numbers for 2008-2012 are 36162-R41-L01 / 36162-RRA-A01 (four-cylinder) and 36162-RMX-A01 (V6). It bolts to the intake with a couple of screws and a connector. For P0455/vent-side codes also inspect the under-car EVAP vent solenoid and lines for corrosion.

Frequently asked questions
What does P0443 mean on a Honda?
P0443 stands for "Evaporative Emission Control System Purge Control Valve Circuit." This is an emissions (EVAP) code. The evaporative emission system captures gasoline vapors from the fuel tank and routes them to the engine to be burned, instead of letting them escape into the air; the purge control valve opens and closes to let those stored vapors into the intake at the right times. P0443 means the engine computer detected an electrical fault in the purge valve (purge solenoid) circuit — such as an open, short, or out-of-range signal. It generally won't affect how the car drives, but it will turn on the check engine light and can cause an emissions test failure. On Honda it is documented across 1 model: Accord.
What are the most common causes of P0443?
The most common causes of P0443 are: Failed EVAP purge control valve/solenoid, Damaged wiring or corroded connector at the purge valve, Short to power or ground in the purge circuit, Open circuit or broken wire to the solenoid, Blown fuse or power-supply fault to the valve, Connector water intrusion or corrosion, Faulty engine control module driver (less common). The specific cause varies by vehicle.
How much does it cost to fix P0443 on a Honda?
Published repair estimates on Honda range from $50 to $250 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
