Component Testing: Canister

On all models, check for clogged filter and/or stuck check valve by blowing low pressure compressed air into canister tank port. Check that air flows freely out of other canister ports.

On Camry, Cressida & Supra, blow air into canister purge port and check that air does not flow out of any other port. On all models, replace canister if it does not operate as outlined.
