P2174 Chrysler -

Question

hi i got a p2174 code on my chrysler 300 05 how to start fixing this problem can you give the information i need thanks

Answer 1

P2174 Low airflow / restriction detected (instantaneous accumulation)

What this code points to is restriction of the air inlet such as the air filter or throttle body. You would have to make sure those are are clear, Then you test the MAP sensor for its 5 volts refference circuit.. If the 5 volts for the MAP sensor is there  you would suspect the MAP sensor. There are cases when P2174 was cause by the timing belt so timing belt alignment has to be ruled out.
