I have an 06 Prerunner and every other week, my CEL comes on. It usually goes off in a day or two, so I never messed with it. I decided to get the codes checked out and it reports the codes as P043E, P043F, P2401, P2402, and P2419. I quick google hit came up with the TSB http://www.empirepao.com/tsb/T-EG025-06.pdf
I am way out of warranty, is this a DIY type job and is the canister available rather inexpensively at a recommended place? I can't seem to locate the part easily. Before buying a new one, is their other easy repair tips?
Lame question, but does this have anything to do with the air filter area, because I changed out the air filter with a permanent washable K&N filter.
