Question about 1999 Ford Expedition

Engine analyzer broken

Hi, my check engine light has been on for a while but everywhere I take it the engine analyzer hook up thing doesnt work. They tell me it doesn't work and they can't read it, and that they get nothing. How do I get that fixed and is it expensive? What could be wrong with it? I've heard it has to do with a "hot wire" that they might of used for my stereo system? I have no idea! My husband doesn't know anything about vehicles either. Help!!!

U need to find out why the system won't self test with the scanner, u have been to a dealer or just some outside shop? Also check the cigar lighter/power point fuse, if it is blown out the system will not self test, the fuse is in the inside fuse box behind the panel to the left of the steering wheel.

There is no fuse. Go to your local parts store and ask them to hook up their code analyzer which will tell you what is wrong. Then they can tell you how to fix the problem. Check engine is no joke and more than likely terminal if not attended to. Most parts stores offer this as a free service. Most vehicles have an access cable connection under the driver side dash board.

My check light is on did a smog tst and faild ,, they said evry thing was fine but could be the egr ,, how do i fix that and around what cost

The first thing you need to do is go to any good auto parts store and ask to use their ECM analyzer. They will loan it to you or come out and connect it for you for free!

The analyzer connects to a port (normally by the drivers side left knee area) and will read out the codes that are causing your check engine light to come on. The analyzer can also reset the codes and you will then be able to see if it is a real problem (the light comes back on) or if it was a "fluke" and the light stays out.

Copy down the codes and descriptions that the ECM analyzer displays because they can be a great help to a mechanic if you do need to have anything replaced.

Reset code for maint/engine light

Try disconnecting your battery for at least ten minutes. Negative cable. Then if and when the check engine light comes back on, take it to a large auto parts chain store like Autozone, Kragen, O'reilly, etc. They will hook up a hand held analyzer to your car and read the code, then give you a printout of what it is. All for free. Take care.

Check engine light

I just did this with my 1996 outback's check engine light. It is some sort of sensor, oxygen, egr, etc. Go to a place like Autozone parts store or any of the parts stores that will do a free test for you by hooking up their hand held analyzer to your computer. They will read the code and give you a printout of what it means. Take care and good luck.

Hi my nissan kubistar wont start and the glow plug light doesnt come on any ideas thanks

hi this could be a couple of thing, but sounds more like the heater relay is u/s, this is the one that heats the glow plugs before starting, check fuse box and see if fuse has blown first, but normally it would be the relay, the other thing could be a bad earth to the engine, check the earthing straps around the engine area, as one could be broken, also check the earth wire connection the heater rail to the plugs ( its the one that runs down the glow plugs and looks like a copper strip or similar ) check to see if is loose or broken...hope this helps please vote thanks

You can take it to autozone, for nothing they will hook a 30 dollar tester to it and give you a guess. You can take it to a real shop or dealer, they will hook a much more expensive analyzer to it and give you a better guess. I have had 4 Saturns, usually it is either an O2 sensor or the EGR valve when the SES lights up, but it can be many different things.It is telling you that someone who knows what they are doing should take a look at it.
