If the check engine light is on I would check for trouble codes first.
If not, look for a vac leak or low fuel pressure.

2003 Ford Expedition - service engine soon light is on


Generally this turn on when have any problem with the emission sensors; to know excalty what fault code there, make one scanned the PCM in autozone or autoshop with OBD Codes Reader.

With this code number we could send aditional details.

Hope helps (remember to rate and comment this).

What is the meaning of CHECK ENGINE ZONE for my ford expedetion 2003 v8 gasoline


http://www.ford.com/owner-services/customer-support/ask-ford-faqs?qtype=uq&inputtext=check+engine+zone

http://www.motorcraftservice.com/pubs/content/~WO3EXD/~MUS~LEN/41/03exdog5e.pdf

I checked the manual for 'CHECK ENGINE ZONE' and could find no reference to this for the 2003 Expedition.

There is a Service Engine Soon light though.

I looked all over the manual and could find no instrument cluster light to that effect.

Can you tell me what page refers to this?

2003 Expedition turns off while driving and check engine light stays on? Will turn right back on but 5 minutes later will turn off again?


When you have the service light come on all the time is simply indicates that there are detected error codes by the car computer that requires an attention.

It does not necessarily mean that it is a problem that will make the car not to run but you will need to get a scantoool to enable you determine what the actual issue is.

Please scan the car.

Cheers.

Ford 2003 Expedition EB. Check Charging System


Its probably the alternator. It will need to be tested on the vehicle with the engine running and the light illuminated. Measure the battery voltage with the engine running. It should be at least 13.5 volts. If it is lower have the alternator tested at a shop with a charging system tester.

Service engine light stays on, Why?


Take the vehicle to an auto supply store and have them read the OBDII code(s). This will give you a general idea of where the problem(s) lie.

2003 Expedition w/ 5.4L engineno power to the engine


Before you start throwing parts at it try taking the bolts out of the starter and inspect the threads.If they are turning black then clean them good with a wire brush.It could be causing you to loose your ground at the starter.
