Codes P0013 and P2199

[bonehead_98]

2005 6.0 pwrstrk, CALID "VXCF43N", Predator sticker "2005 6.0", Tune "u7165_pcm_6_0-9r04 "
Installed 100 hp tune a couple of weeks ago. I have run the truck around town, longest trip about 20 miles overall, again all city driving total miles about 100. I do not dog my truck, I actuall try to keep rpms below 2g. Decided to remove tune and set the truck back to stock. Checked Codes before uninstalling tune and found these.
P0113 Intake Air Temperature Sensor 1 Circuit High Input
P2199 Intake Air Temperature 1/2 Correlation
What does this mean?
like the added pep and seems to have increased mpg, but don't like these codes.
I normally use the 60 hp tune with no codes, but it doesn't seem to help much if any at all over stock. So I tried for the first time the 100hp tune. Now I'm not sure it was a good idea.

Intake air temp is built into the mass air flow meter. Did you happen to install an after market air intake or perhaps clean the sensor that is just behind the air filter. Circuit high is usually when its disconnected. But if the 6 pin connector was disconnected you should be getting mass air codes as VXCF43N is a mass air truck.

Thanks for your input
The truck is completely stock except for a 4" turbo back exhaust. As far as I know the sensors have never been cleaned.

I appreciate the comment from PSDPlayer, but is there anyone from Diablosport got anything to add?

From what PSDPlayer stated is the first thing that we would recommend.

It is related to the MAF sensor which has the Intake air temp sensor built into it. If you have a aftermarket CAI on the truck and over oiled the filter you could of gotten oil on the sensor. If CAI stock it could be just a dirty sensor.

Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension. Also there are 2 IAT sensors on the truck. The other is the IAT2 sensor or manifold air temperature (MAT) sensor is located in the intake manifold. The P2199 code is because the PCM compares the IAT2 signal to IAT signal at initial key on. When the difference between IAT2 and IAT is greater than the specified value for a given time, a DTC is set.

So since the correlation code is present we can assume that the pcm is comparing the 2 sensors and seeing 2 different readings out of them throwing the trouble code. An IAT signal that is detected out of range high or low by the PCM will cause the engine to ignore the IAT signal and assume an ambient temperature of 25°C (77°F). If the IAT2 is showing a different temp which after the engine has been running, this will throw the correlation code.

Dang Cole! How do you check pin tension?
OK, if I understand this correctly, I should be getting the same codes with the stock tune in the truck. I'll check these this weekend. If for some reason these codes do not appear with the stock tune, then is it possible the Diablo tune is causing the problem? If so, what can be done to eliminate the problem?
Oh! Thank you for your response. Very informative.

Based on the calibrations those codes would not be related to the tune. Also P0113 Intake Air Temperature Sensor 1 Circuit High Input is a malfunction with the sensor. To eliminate the codes it to replace the defective sensor. You will see the codes on the stock calibration. Its very possible that it could be an issue with the wire for that sensor in the harness. Also if you disconnect the sensor connector check to see if the pins that are in the connector did not back out where they wouldn't be making a good connection.

Thanks again for your response. Just one more question please. Would this/these sensors have any effect on fuel mileage?

[cole]

Not necessarily. No

[bonehead_98]

Sorry it took so long to get back with the results. I made 2 road trips, both were to the same place and back, about 500 miles round trip each. The first trip was with the stock tune. Checked codes after the trip and no codes. Second trip was with 60 hp tune. Checked codes after trip and there they were. I don't understand. Could it be an accumulation of mileage?
