P2175 - Throttle Actuator Control System - Low Air Flow Detected

Has anyone ever had this code or know what the cause and fix is? It threw the code this morning while i was on the interstate going 75mph. The outside temp was about 16.

I currently have the MM piggyback and power pedal installed and set at 2. I also have the Madness high flow intake with the BMC filter. The car has 10500 miles on it. The filter has about 8000 miles on it.

I have not tried to clear the code yet.

Im very interested in knowing how to solve this as well because my father has thrown this code twice in the last month with the MM ecu set on 2.

Any chance you had the cruise control engaged? I seem to remember that some people were getting a code when using the cruise and the powerpedal at the same time.

P2175-00-THROTTLE ACTUATOR CONTROL SYSTEM - LOW AIR FLOW DETECTED
•When Monitored:
With the engine running, no Throttle Position Sensor DTCs active, and the short term fuel trim is between 17% and (–22)%.
•Set Condition:
The Powertrain Control Module (PCM) compares the MAP Sensor actual to the MAP Sensor model and determines that the intake system vacuum is higher than expected. One trip fault.

Possible Causes on a stock car:

AIR INTAKE SYSTEM OBSTRUCTION
EXCESSIVE RESISTANCE IN THE MAP SENSOR CIRCUITS
EXCESSIVE RESISTANCE IN THE THROTTLE POSITION SENSOR CIRCUITS
MAP SENSOR
THROTTLE POSITION SENSOR/THROTTLE BODY
POWERTRAIN CONTROL MODULE (PCM)




NOTE: The most likely cause of this DTC is a plugged intake air system or dirty Throttle Body. Check for any TSBs that may apply.

(Inspect the Air Filter and intake inlet for debris such as ice, snow, water or mud that may be causing a restriction.

Also check the Throttle Body for blade and opening for excessive build up.)













NOTE: Diagnose any 5-Volt Reference, TPS, Fuel System Lean or Rich, or MAP Sensor DTCs before continuing.

Do you have the remote for the MM Modules? Did you try changing the setting while the car was moving?

I do not have the remote option.

So I drove to lunch and the CEL was still on. When started the car to come back to work the CEL was gone. I hadn't checked anything that was suggested and i hadn't cleared the code. Is that a normal thing for the ECM to do? Will it clear the code itself if it is no longer seeing an issue?

I did have the cruise set. I also had the ETC light(red lightning bolt) when the CEL came on originally. I pulled over and turned the car on/off and the ETC light went away.

That happened to me with an MM unit and SprintBooster. It was the original MM program though. Does your MM have the latest program?

I had same red Lightning light many times during long hwy runs on cruise. Sometimes it would come back in only 20 miles sometime not at all even in 400 miles. Restarting engine gets rid of it and gets your boost back. I had MM box and I think it does like to mess with cruise control under certain conditions.

Is your car a 2012 or 2013 Abarth?

I'm pretty sure it has the latest version. I will do a reset on it this weekend and make sure.

My father got the exact same code and just like you it goes away after awhile. His is a 2013 as well. This is really weird.

It is a 2013.

Very odd. According to a Fiat Tech, that code was specific to the 2012 only. Let me do some more digging for you. If you PM me the last 8 digits of your VIN, I can do a little more research for you.

He did say to check the MAP sensor connection and the throttle body connection.

Here's a pic of the MAP Sensor connection. It's above the A/C Compressor on the intake:

Thanks for all the input and assistance. The code is gone for now.

Just to add for those searching P2175. I got it coming to and returning from The Dragon meet in my 2013 Abarth C with MM ECU, ram air boot, K&N and after airbox intake tube. It was also under cruise control after several hundred miles. It came at the same time as the red blinking Electronic throttle control light. The ETC light went out after turning off the car and I reset the P2175 via Dash Command.

Yeah, I'm headed back from the Dragon now and had it come on. Did the same as we were leaving the hotel for devils triangle the other day. Also have the MM ECU on my 2012 Abarth. It's been happening more often lately but easy enough to clear

This is odd my father and I both got the p2175 code on the way to the dragon. We both have the MM ECU. We both have 2013's. We were both on cruise control at high speed for a couple of hours when it happened.

It looks like it only happens with cruise control. I just plug my bluetooth OBD2 in every couple days and clear the code now, before the light even comes on. Are you guys on the 58% tune, or the old 77% tune? I'm on the 58

My father and I are both on the 58% tune. I also noticed that it only happens at high speed cruising above 70mph.

Sounds like a bug in the MM box software.

I don't recall the exact code now but I can tell you guys (as we discussed briefly I think) I too had a CEL after a few hours with cruise control (and Sport Mode) but I am using a 2 wire TMC so it isn't specific to the MM box. Okay, at least a CEL isn't just due to the piggyback, that specific CEL however might be related to the MM unit as I know one of mine was P0299 (under boost issues).

Side note, great meeting everyone and really enjoyed our Abarth only Sunday ride...I was closer to home so left and went the opposite direction you guys went and say a sweet Ferrari although not sure what model as we passed each other rather quickly. ;)

I used to get that 2175 with my MM. Got rid of the MM long time ago and switched first to a TMC and then RRM U3. Never had the code since ditching the MM.
