The On Board Diagnostics system in your Ford Taurus is a complicated computer system that governs your Ford’s health. It communicates through a port located under your dash, and can inform you when there’s a problem with your Taurus. It notifies you through a Malfunction Indicator Lamp (MIL) or Check engine light.

When the Check Engine Light or Service Engine Soon light turns on in your Ford Taurus dash, your OBDII system has detected a problem. There are many different types of errors your Ford diagnostic system can detect, and can put your engine into limp mode if it feels as though the error or problem is serious.

 

Limp mode can cause your vehicle to run very roughly, and is intended for you to literally limp the vehicle to your nearest service station. Problems with your check engine light can range from small problems, like not having enough fuel or a loose gas cap, to bigger problems, like a bad crank position sensor, or mass air flow meter.

Your OBDII system requires three separate driving cycles in order to illuminate your check engine light. If your problem or condition is not present for three consecutive driving cycles, your MIL may be intermittent.

Ford outlines the parameters of a driving cycle as starting your engine from a completely cold condition and driving your vehicle for about 10-15 minutes. If your problem is repaired or taken care of, you can attempt to clear your Ford Taurus code by driving and completing three seperate driving cycles.

If you can’t wait and want your Ford Taurus check engine light taken care of sooner, you can always rent a scanner or OBD scan tool. When you use a scan tool or scanner to connect to your Ford Taurus computer, you can read or pull the codes from the vehicle. This can give you a good start or a good idea as to what the problem with your vehicle is.

You can also clear or reset your MIL status to clear your Taurus check engine light. Be sure to note all of your available trouble codes before clearing your ECU.

There’s a few different ways to tackle the job of resetting your Ford Taurus check engine light by way of your EFI fuses or relays. Open your hood and locate your fusebox in your engine bay. Depending on the year range of your Ford Taurus, this may differ from vehicle to vehicle.

For the first generation of OBDII Ford Taurus vehicles from the years 1996–1999, this fusebox is found in the engine bay near the firewall. For all 2000–2007 year range of Ford Taurus, the fusebox is located near the front of your engine, on the passenger side.

Remove the fuse block labeled Engine Control or EFI 1 or 2, for earlier models between 1996-1999 this fuse can also be labeled EFI. Remove the fuse and head back into the cabin, and turn on your headlights to completely drain your car. Wait 5 minutes and then reset your vehicle’s ECU by re-installing your fuse. Turn the vehicle back on and complete a driving cycle to see if your trouble code returns.

  1. I have a 2007 ford taurus sel with 99456. Mile
    All 4 Oxygen sensers replaced twice and mass senser placed for lean code light back on after flushing fuel system have no clue please help.

    • Hi Mark, quick question.. you changed your oxygen sensors but the Mass air flow sensor is still triggering a OBDII code? do you have a scanner or know what code your Taurus is throwing sir? Let us know and we’ll be glad to help! Thanks for commenting!

  2. 2904 Taurus check engine lit comes on and off, doesn’t seem to complete the drive cycle so is not ready for smog check. Replaced the Cat and this code cleared..now just can’t get it to complete the cycle. We are not failing smog just getting a no test due to not being ready. We have driven car for 50-75 miles and on highway..help! Thanks!

    • Hi Amy, sorry to hear about your situation but unfortunately there’s no getting around the MIL status. You need to put miles on it to get all the MIL statuses to clear. Try different kinds of driving, up hills, on the freeway, etc.

      Let us know how it turns out and thank you for commenting!
