service engine soon light.

Scan the computer for code/s might not be for the EGR valve this time.

Please run down this guide and report back.

My Check Engine light came on and carried it to tech. and he said that the fuel sensor detected the
gas tank to full or it can do it if tank is close to empty.
I'm guilty of topping the tank as much as I can, even
overfilling sometime. I've never heard of this before and why didn't it go off over the past years that I
have overfilled? Is this a true reading?
Thanks, Bob

can you give me the exact code?

Sorry, I did not get code. So, I guess this ends my
question. After surfing around your web page, I
didn't know there were so many codes.
Thanks for your help. Bob Argo

I found my copy of the ticket and on it I located
the code. It's PO460

Thanks, Bob Argo

PO460 means fuel level sensor circuit malfunction.

means that the fuel tank sending unit is defective or that the wiring harness in the cluster to the unit is bad

Why does the Check Engine Light come on?

HI there,

The check engine light is an indication the one of the engine management sensors has failed or is out of range, the ECU take the information from all the sensors to operate the engine in optimum performance , if a sensor is out of range the ecu will log it as a fault code, this code is unique to each item it is monitoring so the code number is require to identify where your problem may lie.

when idling my 02 mustang sounds great but when you get driving down the road it barely wants to run and the service engine soon light starts blinking their is a smell like raw gas fumes or something under the hood when checked at advance on computer it reads an agr code but if the llight is blinking when it is checked it reads cylinder misfire all new plugs and plug wires are in my car....please help.....

Misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

This morning as I was driving to work my car started to pull really bad like i was stalling and wouldn't go past 3000 rpm and my engine light started blinking. Also heard a knocking sound too. what is the cause of that.

Hello Jennie !

Did you continue driving the car ?

Check the Fluids as soon as possible !

Water, Coolant on reservoir, Engine Oil, Transmission oil and power steering fluid...
Let us know what is the condition and levels..

We Will be here waiting for your answer..

I had an engine misfire and did a diagnostic code p0401. I didn't continue driving I was only around the corner from my house so i turned around and got my other car. My husband will replace my spark plugs and my change my exhaust gas circulation.

Hello !
got scared! I thought it was a low oil engine... (heard a knocking sound).
He Is Right..
P0401 Exhaust Gas Recirculation Flow Insufficient Detected

could be EGR Plugged or malfunction ..

Anyhow .. Let us know!

Good Luck and thanks a lot for your donation!

My 2002 mustang has the check engine light on. The DTCs it's giving me are: P1000, P0133, P1131. Now the O2 sensors are BRAND NEW, just replaced them. An so is the header gaskets, because I just put a full exhaust on it. But these code were on there before I did this, so I know it wasn't a mechanical mistake... But I can't find out what it is... Can you help?

Yes I can help. I will look up the codes when I get home and walk you through it if you still need help. So let me know if you haven't fixed it yet.

P0133 Intake Air Temp sensor fault
P1000 Diagnostic not completed commonly set when BATT disconnected
P1131 HO2S-11 Rifht side bank O2 just before flange.
Try clearing see what resets

My name is Tony. I have a 2002 Ford Mustang, 142K, V6 3.8L. I just changed the fuel filter the other day. But after a point in time of driving, it starts to bulk down and eventually cuts off. The check engine light is on. My uncle once told me that it might just be the spark plugs. He said it sounds like it's not getting all of the power. I haven't changed them yet. But do you think that is it?

I would be pulling them out not based on the uncle but because I would want to know how they looked. Take a look at them and see if one or more of them looks a bit black. I may be noticeable from viewing the plugs what is going on. Let us know what the condition of the plugs is.

Have the PCM scanned for the codes

I have taken my 2002 Mustang into the shop several times for intermittent problems starting and running typically in , but not exclusive to, cold weather.
The engine turns over but will not "catch" and run on it's own without keeping the accelerator down slightly and keeping the RPMs up. Letting off the gas while braking will result in a stall.
The dealership can never find anything wrong. The problem seems to be one of those elusive ones that won't occur when it's in the shop and you feel like they are looking at you like you're crazy or something.
They said that the diagnostics test yielded no problems despite the SERVICE ENGINE SOON light being lit. The starter has been replaced but made no difference.
Any ideas other than the obvious "Take it somewhere else"? This Ford dealership is one of the only ones that honor my aftermarket extended warranty. (But that's a whole nother topic)

The first question to ask this "Dealer" is what are the codes, You are entitled to get a printout with the code numbers and meaning...have them supply it, and we can figure it out! You allready paid for it, so tell the service desk you want a copy!

Ford 2002 Mustang GT Automatic V-8 sounded like a loud pop from rear of car then very loud sounding air noises and a clanking sound from front end started and continues each time its started back up no visible leaks from vhicle and check engine light not on at time and oil is registering on the dipstick when checked.

Open hood and check for the source of the air leak
check vacuum lines and belts and so on
if not and or not sure
Should have it towed to a local shop and or have a tech take a look at it

my mustang started misfire. the code said number one misfire. I put on new wires and plugs and air fllter. Service engine light went off but now when giving gas it sputters what could be wrong

Correct plug and gap? wires seated well to plugs? Could debris have gotten on MAF when filter changed?
