1998 Ford Expedition - Answered Questions & Fixed issues

fuses should be clearly marked on inside of fuse cover or in your driving manual which came with the car

Question edited for clarity and typos. Question moved to model category. $20, $80, or $112, take your pick. Don't go too cheap on sensors though as they are important! https://www.google.com/search?q=1998+Ford+Expedition.+replacement+anti+theft+transceiver+ring+sensor ..

Sounds like you have a slight pressure leak somewhere in your system. I would get a spray bottle with some soapy water in it and spray down everything. Every line, every fitting and each shock and the compressor. Look for something that is making bubbles.

First thing I would do is have someone qualified disconnect the alarm and stereo and start over.Chances are you have circuits cross-connected and something is draining the battery.

it is not a vacuum hose, i have the same problem. you need to change the oil and oil filter, then spark pugs and ignition coils and wires. and then finally the fuel injector connections. hope this helps:)

You would do both sides
Have heads checked for cracks
and pressure tested
On a 12 year old head,I would do
the valves etc

$2000.00 or more,if you
pay someone and not do yourself

Real vague. I will assume that the noise is the sway bar frame bushings. On a bump they can sound like a large hammer hitting the frame. If I am correct, there is no trick. They are not loaded, no pressure on them. The sway links are not loud. Control arm bushings squeak, not clunk, due to the fact that they are always loaded.

2005 5.4 expedition is 1326548 --standing in front- to your left are 4 plugs designated as 1234 and the right side is 5678,

change the crank sensor

Start with changing fuel filter and check fuel pressure.

Spark plugs number starting on the passenger side, front to back, #1 to #4 and the driver side #5 to #8 front to back.

You must make sure that (1)the line is tight but not over ightened if over ightened the flare has cracked and must be replaced (2)be sure you are flaring the tubing correctly that the tubing is sitting properly in the flaring block and that your are cutting the tubing evenly (3)inspect the fitting on the master cylinder and that the new line fitting is// the proper size////metric or sae/////and the master cylinder fitting is not cracked===== also the brass block is a union for both rear wheels you will see the other lines coming out to each wheel unless it' up front then that is a proportional valve ok but I think you have either a cracked line or fitting from over tightening or you are trying to mate an sae fitting with a metric one or improper flaring and crooked tube cutting good luck stephen

Unfortunately, I have the same issue in my 2003 Ford F350. It is either the module or there's a relay that is not in the wiring system diagram believe it or not because underneath the dash on the driver side hidden away of course and is very difficult to get to.

Sorry, I only saw one oil pressure sensor for your vehicle and it screws into the oil filter adapter. I did look at oil pressure, it said 20--45 psi@1500 rpms. Any specs you see on the internet you would probably be wise to double check. All databases are not created equal. You might be able to use analog gage in place of oil pressure sending unit to double check oil pressure.

probably not a major fix but a TR sensor or VSS sensor problem take it to a professional auto transmission shop for a proper diagnosis and reading of the fault codes

Just wanted to say that there is a plastic bracket holding the steering hose to the frame as it goes to the steering fluid cooler at the drivers' front of grille. They usually leak as moisture and salt are held against metal line held in this bracket.
