Quote: P 41 code is normally an oxygen censor code. I do not have my OBD 11 with me or any other code books for OBD 1 with me also. Since you have found the code I believe your truck runs OBD 1?
P41 is swapped 02 sensor code, bank 1, sensor 2, bank 2, sensor 2
OP, you either misread the code, or you have other issues
