Altima Check Engine Light w/P1448 Code
My 1998 Altima is showing a P1448 & P0440 trouble code. From what I read, the usual problem seems to be a vent control valve located on the charcoal canister.
Am I correct?
I was able to separate the valve from the canister (not fun - totally rusted) but I'm not sure how to test it. Do I just run a jumper wire from one prong on the valve to the positive battery terminal and then a jumper wire from the other valve prong to the negative battery terminal (or ground)?
Does anyone know the exact part number for this? I think it is 14935-54U04. My local dealer wants $117 for this little thing! Where is the cheapest place I can get this part online?
Thanks
