I recently bought an 01' firehawk trans am and the SES light came on a month after I got it. I hooked it up to the scanner and the purge valve code came up so I replaced the one on top of the engine and deleted the code. Two days later SES light is back on so I hook it up again and it is saying the purge valve canister or something is bad, and I asked my mechanic friend who looks it up in the manual and says that one is on top of the gas tank. Does anyone know if I have to pull the gas tank to replace this or is there an easier way to do this or if this is even the problem?....it would be a real pain to rip out the gas tank for a 20 dollar part.

 

What is the exact code? Yes, the EVAP charcoal canister is indeed on top of the gas tank, and there's no easy way to get to it.

 

that canister is only 20$ ???
