EEC code 114

[92ShoOff]

So last week I ran a diagnostics scan on my '92 becuase the check engine light was coming on... I had plug wires that were falling apart, along with fouled Champion spark plugs that were soaked in oil. The code was reading 114, however... which is the Air Charge Temperature sensor. I got a new one from Ford and this past weekend I tore the top end of the motor off. I went ahead and replaced the valve cover seals and oil well seals to keep oil from getting in the plug wells, and I of course replaced the Air Charge Temperature sensor while I had the intake off. I finished everything off by installing new Motorcraft Platinum plugs, and Magnecore plug wires.

I tried to erase the code after I got everything back together and running, but the code is still popping up. What else could be triggering that code besides replacing the sensor? I was wondering if the bad plugs and wires caused the code to come up somehow by damaging a sensor or something. What do you guys think could be the problem?

The ACT shares a common ground with the MAF. I would check for a MAF out of calibration. How does the car run. More specifically, how is throttle response?

How do I check to see if the MAF is out of calibration?? Acceleration seems fine and the engine seems to run fine other than the problem I just posted in this same forum topic about my secondary runners possibly not opening up. So I'm not getting that "kick" after 4,000 RPM, but everything seems fine other than that.

The ACT sensor code is going to continue to show up. For some reason it'll throw a 114 code if the temperature is between a certain reading. Something like 40-65 F. Don't quote me on that I'm probably wayy off. I pulled my codes today and got the 114 code also. It's nothing to worry about. I could probably pull my codes tomorrow and it'll be gone.

I've been around since '96 and never heard of such a problem. I believe the 114 can be caused by the MAF, you can most likely find your answer on the topica list, via keyword search. Tech SHO list also has very valuable information as well.

As masho95 mentioned, an ambient temperature below about 50 deg. F can trigger a false IAT (ACT) code 114 on some cars. (DemonNeno if you haven't heard of this try running a search of the forum for code 114 and look for replies by either sdpatt, projectsho89 or rangerj.)

If the outside air temp was around or below 50 deg. F when you received this code, I'd recommend waiting until the next time the temp is closer to the 60 deg. F range to run the codes again to see if it recurs as a hard code.

I am a little confused by you mentioning having to remove the intake to replace the IAT sensor. It's located in the side of the airbox and can easily accessed without touching the intake.

If I recall, it was well above 50 degrees both times I ran the scanner on the system. The check engine light has been on for over a week now with this code, so I don't think it's going to go away on it's own unfortunately.

The reason I pulled the intake however is because I was changing the valve cover seals and oil well seals. So while all that top end of the motor was off I changed out the ACT sensor. I don't know if the location on the 3.0 motor is different than the 3.2, but it looked like the only time I was going to be able to change out that sensor was while the intake was off anyway. I had to use an open-end wrench to replace the sensor because I didn't have a deep enough socket to go over the connector on the sensor... so having all that off gave me a lot more room to swing a wrench.

Regardless I'll trying running the scanner again today when it's warmer and later tonight I'll try to find search those messages you were talking about that were posted some time back.

Thanks a bunch guys!

Where exactly was the sensor located that you replaced?

You didn't replace the ACT I don't think.

The ACT sensor, or 114, will NOT make the CE light come on. You have another problem, so be sure to check your stored codes. The ACT sensor isn't the sensor you changed out by your description then. The ACT sensor is located in the air inlet tube then goes to the throttle body. The ACT sensor is mounted in the blue air inlet tube in the picture.

Well crap, my dad pointed the part out to me when I had the intake removed and when i ran to the Ford dealer and asked for the "Air Charge Temperature Sensor" they gave me that exact same part that my dad had pointed out.

It was mounted to the block if I recall. It was located underneath the throttle body though, kinda buried in a spot where you'd have to have the intake off to get to it.

It's just strange how that's the part my dad pointed out and when I went to the dealership I simply told them what part I needed and that was what they gave me. I'll have to look at the receipt and see the description of the item. Hmmmm... now I wonder what the heck it was that I replaced? Lol. Well thanks guys, you're being a lot of help to me!

Sounds like you replaced the knock sensor I believe.
