Having problems with your Dodge Intrepid ?

I have a code P0172 code, took apart the intake and cleaned all the sensors. Gonna check PCV valve tomorrow. Is there anything else to cause this problem? Also is it worth trying to repair the blower motor resistor (has only high), I'm handy with electronics. Thank you for your time, Benny

Answers :

  • Inspect all vacuum and PCV hoses, replace if necessary \015\012
  • Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling \015\012
  • Inspect fuel lines for cracks, leaks, or pinches \015\012
  • Check the fuel pressure at the fuel rail \015\012
  • Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced. \015\012
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)
  • \015\012
  • Blower motor relay is a good fix cause it breakes down the voltage for blower speeds wich is controled from the head inside the car.
  • Po172 is too rich condition.
    \015\012Perhaps an O2 sensor is causing the problem, or a sensor that control fuel delivery.
