luzmina Posted January 20, 2021 Report Share Posted January 20, 2021 My 2.4 liter 2013 with 80K got the P2173 HIGH AIRFLOW/VACUUM LEAK DETECTED (SLOW ACCUMULATION) I ran a smoke test and no leaks from the intake or any hose, I replaced the Throttle body and the code return, I replaced the Mass sensor and the code return, I replaced the Brake booster and calibrated the Throttle body and the code return after 3 weeks, finally I decide to change the intake manifold gasket 2 months ago, so far it looks that is fixed for good, I found the old gasket was leaking between two cylinders thus the reason the smoke test did not work, to any one with this code I suggest to replace the gasket first, is only $6.00. The P2173 will put he car in limp mode and make it undriveable Summer Solstice, John/Horace, 2late4u and 2 others 1 1 3 Quote Link to comment Share on other sites More sharing options...
mikecast Posted February 2, 2022 Report Share Posted February 2, 2022 I got the same code after installing new throttle body, could it be the gaskets on the manifold? Is it a simple tasks to do or not ... Quote Link to comment Share on other sites More sharing options...
John/Horace Posted February 3, 2022 Report Share Posted February 3, 2022 Lots of bolts on a expensive plastic intake housing, torque wrench required IMO. Awkward back of the engine work, not simple. Wouldn’t be my first choice to do that. Did you use a new gasket with the throttle body change. I would start with changing that first if you didn’t. Make sure intake plastic snorkel is properly put together at all joints as well. Free advice worth everything you pay for it. Quote Link to comment Share on other sites More sharing options...
luzmina Posted February 3, 2022 Author Report Share Posted February 3, 2022 Is no hard to change it, maybe 2 hours, search for a video, is same as the Avenger or other Chrysler with same 2.4 engine, the code has no return after the fix. mikecast 1 Quote Link to comment Share on other sites More sharing options...
