i have code 54, i know its the crank fluc. sensor, but where does it plug, i know its located on the crank blahblahblah...but shouldnt the plug come out of the lower timing cover somewhere? or am i wrong?

 

I am throwing this code as well... on my 2000 ITR.

Just swapped in a stock CAT and a known-to-be-in-working-condition o2 sensor (my stock o2 sensor is broken and my CAT is hollow... grrr, previous owner). Anyway, immediately upon start-up, the Teg threw code54.

I looked it up and believe it is: "P0054 HO2S Bank 1 Sen 2 Heater Resistance".

I have searched around the site and can't seem to find out what this code means exactly and what I need to do to fix it. I have to pass emissions! lol.

Anybody have any advice?
