hello, this code is for the evap canister pressure sensor, it's part of the canister assembly so the entire canister should be replaced, you should also inspect dor any broken or cracked vacuum hoses and the electrical connections at the canister sensor and VSVs.

I've checked all connections. They look like new. The systems holds vacuum all night. What is in the canister besides charcoal?
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 1 month ago

That's about it , there are some sensors and vacuum switching valves, the pressure sensor is part of it and that's the reason the whole canister needs to be replaced.

Don't blame you, by the way the trac control or vsc lights will go off once the check engine light stays off.
