1997 Toyota Camry Q&A
1997 Toyota Camry Question: P0441
toyota has tons of evap problems. they reccomend replaceing the cannister assembly. first, make sure your gas cap tests out ok. there are 2 soloniods that fail on the cannister and usually break when removing. that is why the assembly is reccomended. the cost is about 300 for the cannister and 1 hour in labor.

Check that none of the small (3/8 diameter) hoses were not accidentally knocked off at the rear side of the air filter housing, happens a lot when people replace the air filter and sets evap code. - patrick mannion
It could be a hose attached to the purge VSV. The purge VSV (motorized value) allows VPS (vapor sensor) to determine whether there is a vapor pressure difference between the fuel and the charcoal canister. When I was replacing the EGR VSV which is located at the bottom of the engine, I removed the hoses to the purge VSV thinking that I found the VSV I wanted to replace for a different engine code. When I discovered the EGR VSV was near the bottom of the engine, I put the three hoses back on but the purge VPS, but I put VPS hose on port F instead of port E and it gave me a P0441. It took a lot of research to find a 1997 EVAP diagram with the hoses and the ports. My point is that one of the hose could be clogged on the purge VSV and give you that code.

Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.
