What is the PJB fuse on ford exploror - 2004 Ford Explorer

for me it led to wheel bearing failure. I guess the abs sensor is in the wheel bearing housing.

sounds like a job for a Chilton's guide..

PJB?

If by 'power leak' you mean 'system draw', swap out the a/c clutch relay with another relay in the box (lights, horn) and see if your draw goes away. Ford had a problem with their relays staying on. Don't forget, high end Ford/Lincoln cars take 15 - 20 minutes to power down their systems.

I have a 2003 mercury mountaineer with a dying battery problem and we narrowed it to fuse 1 and 29 and they are labeled PJB in the owners manual....if you find out what that means I would like to know too. I don't know if that will help you any

1/2 the fuse box is controlled by that. Ignition system mostly.

sounds like keyless entry module failure or PJB box failure wiring check required

All other gears work? Can you desribe the part? Can you push the vehicle forward or backward in park?
