bobbydd21 Posted October 22, 2019 Share Posted October 22, 2019 (edited) Does anyone know if this connector is suppose to go to anything? Cleaned out my air filter last night and now I’m getting engine codes P0171 and P2270.... https://ibb.co/kScsnPx https://ibb.co/Lxsx3p2 Edited October 22, 2019 by bobbydd21 Link to comment Share on other sites More sharing options...
ammcinnis Posted October 22, 2019 Share Posted October 22, 2019 (edited) That looks like the connector for the hood position switch, a component of the optional remote start system. What do you mean by, "Cleaned out my air filter?" It appears not to be stock.

I rinsed out the filter with water (as I normally do a few times a year), let it dry, and reinstalled. Now I'm getting these two codes thrown. No idea why.

iyalla Posted October 22, 2019 Share Posted October 22, 2019 There is an air leak somewhere. Go through your steps again. Slowly Link to comment Share on other sites More sharing options...

It would have to be a leak after the MAF and I didn’t even touch any of that. Link to comment Share on other sites More sharing options...
moral hazard Posted October 23, 2019 Share Posted October 23, 2019 Time for more general troubleshooting then: code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor Possible cracked vacuum or PCV line/connection Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1) Sticking/plugged or failed fuel injector Low fuel pressure (possible plugged/dirty fuel filter!) Exhaust leak between engine and first oxygen sensor https://www.obd-codes.com/p0171 Do you have a mate that can lend you their MAF sensor for a test ?

Just cleaned the MAF and the filter is not oiled. Still got the code. Only thing I can think of is maybe one of the rubber couplings got a small hole in it from being pulled to reinstall. Going to try and replace all of those first and see what happens Link to comment Share on other sites More sharing options...
bobbydd21 Posted October 27, 2019 Author Share Posted October 27, 2019 Update: As expected, it was a vacuum a leak. One of the silicone couplers must have had a small hole because I replaced them all and it’s fine now. Thanks everyone! Link to comment Share on other sites More sharing options...
