KOEO Code 114

[CTOESHO]

I ran a search and nothing came up. What does it mean when the ACT is out of self-test range? The ACT sensor is less than a year old also. Thanks.

It means the PCM tested the ACT (Air Charge Temperature) sensor but got a reading that was outside its expected parameters. Look for a bad connector (open), a short circuit, or a defective sensor. The sensor can be tested with an ohmmeter. Ignore this code if the ambient temperature was below 50 F at the time of the test.

Measure the resistance of the ACT and post the indicated value along with the ambient temp and I'll tell you if it's bad or okay.

Great, thanks for the info. I will test it tonight and let you know. Thanks again.

37-38K Ohms

FWIW...I just happened to swap out my ACT @ ECT sensors last night...ambient temp was about 60 deg.

Old Ford F32F-12A697-AA: 36K Ohms
New Wells SU203: 39K Ohms

I also swapped out the ECT sensor as well....

Old Ford E4AF-12A648-AA: 38K Ohms
New Wells SU201: 48K Ohms

No difference in performance.

I perviously had a CE on a cold morning, and a 114 code resulted,

The 114 code was a result of testing it when the ambient was below 50 F (or when the sensor thought it was). Disregard this code if temp is below 50F.

There is no provision for a continuous/stored code of 114, it can occur during either the KOEO or KOER tests.

The temperature vs resistance curve for the thermistor is not linear, it is somewhat hyperbolic. FYI, the reistance at 50F should be around 58.75K, 68F - 37.30k, 86F - 24.27, 104F - 16.15K, 122F - 10.97K, 140F - 7.6K, 158K - 5.37K, 176F - 3.84K, etc... These values have a 15% tolerance.

If the ambient temp in which you tested the sensor to be 37-38K was around 68F, the sensor is fine.

Well, I took the sensor out and went inside and tested the ACT sensor within 5 mins. The temperature outside was about 40 degrees and rainy. It was probably around 65 degrees like you said inside when I tested the ACT sensor that resulted in 37-38K, but is 5 mins long enough for the sensor to warm up to the 68 degrees? Thanks
