SOURCE: ABS light on a 2004 Mercury Mountaineer. How do I

Go to Autozone or Oreillys and see if they have a scanner for the ABS system. They usually scan for free.
The ABS will measure braking problems and things like worn brake linings and debris on wheel sensors.
You would want to verify the code light and then have the lining visually inspected.
There can be problems with the emergency brakes which require the rear rotors to be removed from the vehicle. Some of the rotors are a problem to remove because of rust.

SOURCE: mercury sable 2001 duratec engine DOHC I get check engine light and diagnostic code PO401". Any suggestions?

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

Mercury Mountaineer 2000 clicks while trying to start, turns over good with jump box but still wont start?


This engine is computer controlled, so when it stalled out the computer will almost always set fault code(s) for the problem if it is a component like a crank sensor or other device, if the engine failed in some strictly mechanical way then no code or codes may be present. You need to have the system scanned (diagnostic connector under the dash drivers side) for fault codes as a first step toward repair.

I have a 2005 mercury mountaineer the wrench light and service engine light comes on and moves very slow only in reverse witch causes the overdrive to light up as well what is wrong


Hello Veronica

The 'wrench light' is actually and 'engine malfunction light'. Something has failed, probably a sensor, and your vehicle is in 'limp mode'. Supposed to be just enough to get you to a garage. They will put it onto a Code Reader and then that tells you were the fault is and what needs replacing.

The error codes can be found here

How do I fix it 2005 Mercury Mountaineer with the overdrive light and check engine light coming on


Fault codes are there for a reason. Fuel injection engines were designed in the 80's to reduce pollution and protect the ozone layer. a malfunctioning fuel injection engine will cause pollution. Replace all bad sensors. Your engine should reset itself. in turn will run better, efficient and improved performance.

I understand all you said

Without the vehicle and a fresh
diagnostic approach, I personally
don't think any internet ideas will help

You still have misfires, that are spiking the PCM &
TACM on the throttle body and putting it
into ETC Fail Safe.

03 mercury mountaineer, service engine soon light came on. i was told it needed a oil change . we did that , now how do i get the light to go off ?


Your Service Engine Soon light has nothing to do with reminding you to change your oil. The light is controlled by the ECM (Computer) in your vehicle. It monitors various sensors in your engine and compares them to variables or programs that is in its memory. When something is not registering correctly or is outside of its parameters it will turn on a MIL(Malfunction Indicator Light)or in your case a Service Engine Soon light. You will need a OBD II ( On Board Diagnostic) reader or scanner to hook up to your diagnostic port under your driver's side footwell to read what code the ECM is putting out. Than with the code the mechanic can look up the code to see what part is sending a malfunctioning. The scanner can also read and erase the code too. You can have your code pulled up with a OBD II scanner for free from any AutoZone store.

In 97 mercury mountaineer, how to turn off "check engine" light


Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.
