You are watching: 2002 dodge ram 1500 code p1491

Hopped in my 2002 Ram1500 to go to job-related this morning and also I acquired an engine light. Did the three vital jiggle and out popped a P1491 code. Looked it up in ~ work and a short article on an additional forum led me to the number 39 fuse ac fan relay or something.After job-related I confirm the fuse and also sue enough it to be blown. I stopped in at Fred Meyer to gain a replacement. Put it in and also cleared the code once I acquired home. The irradiate is currently off.I am not sure why this fuse go out. Lock don"t just randomly go out. There has to be a root cause here somewhere. If anyone else has any experience with this issue, please let me know.Thanks.
