You do not have a barometric sensor. The engine computer calculates the barometric reading based on the sensor input it receives from your Mass Air Flow Sensor.

The MAF is located near the air filter box, in the air intake hose. Make sure there are no rips or tears in that hose.

Next remove the MAF (you'll need a safety-torx or tamperproof-torx driver for the two screws) and spray down the filaments with Intake cleaner or Electrical contact cleaner. You can use a q-tip to wipe it clean if you're very careful, as the filaments are very fragile. Sometimes these get dirty or oily (especially if you use an open air filter, or a K&N style filter).

Then reinstall, clear your codes and see what happens. You may need to actually replace the MAF as sometimes they get so bad cleaning won't do the job.

Keep in mind this is all assuming you have a BARO code. Scanner desriptions aren't always correct, so you'll need to post the EXACT CODE for me to be certain.
Hope that helps.......

These all are different sensors around the motor, yes replacing them if diagnosed as faulty by your ford dealer should / may solve the problem in my opinion.

It may also be caused by something else, and I would recommend taking it to a repair man.

If you feel that my solution is not satisfactory, request more assistance / repost the problem. Theres a button / link for that somewhere on your side.

Thank you,

You should ask them for the part numbers for those items. I am having trouble finding them by your description.
Thanks,

    Did you get the part numbers like I had previously asked? It can be alot of things. Your tps could be dirty. Your EGR valve could be clogged. Your best bet is taking it to a trustworthy professional.
    thanks,

    Your MAF sensor connection could be dirty or the sensor can be clogged or in need of replacement.
    Thanks,

I have been having problems with my 1998 ford windstar 3.8L with rough idle and dying, i changed the mass air flow sensor, and air filter, ran gas treatment through it, and it hasn't helped, then yesterday...


I have a 98 Windstar and it would die when pulling up to a stop sign, slowing when coming to a stop or making a slow turn. According to Ford recall 98E03 EMISSIONS RECALL some vehicles may stall during deceleration when coming to a stop, during slow speed parking maneuvers and/or coasting thru slow sweeping turns. This may be caused by the Powertrain Contro lModule (PCM) calibration dropping the rpms too quickly during deceleration. This involves reprograming the PCM. The revised calibration will allow the engine rpms to drop slowly during low speed maneuvers to reduce the possibility of a stall. Call your local FORD dealership (have your VIN handy) and have them check to see if this recall has been performed on your vehicle.

I have a 1998 ford windstar it wont start or turn over this happend befor i let it sit for a month and it started up with no problem i took it to the shop and they looked it over and said they couldent...


You have a "park" interlock that could be failing.
Please Place the gear selector in "N" and see what happens.

Then, Connections at starter selenoid, failing battery terminal (or bad connector). A battery could have a broken plate inside that will not feed power to the starter - sometimes.

Check battery voltage.. If 12.5 or better - ok
Have a helper start the engine while you monitor the battery voltage - if, while in the start position, the voltage drops below 10 volts, replace the battery.

If the battey voltage holds at better than 12 volts, then You try to identify a bad positive cable connection between the battery and the starter as follows":
* Have your helper place the key in the start positition and HOLD IT THERE until the engine turns over.
*If, while in the start positition, engine does not turn over, then you should check for connections at the battery terminal---starter selenoid---selenoid output---starter connection. Again, all with the key in the start position.

If you wiggle/poke/prod a crank out of the starter - then you have identified the problem...
