Question
my 2003 caravan has a p106 diagnostic code can you tell me what this means?

Answer
Hi Wendie,
It says that the sensor that measures the pressure in the intake manifold is outside the range of normal, suggesting either that the sensor is bad or its wires have been compromised. It is mounted on the intake manifold adjacent to the power steering fluid reservoir (3.3 or 3.8L engine). It has a plug with a 3-wire harness. So find it and then inspect the wire harness for signs of damage to the insulation and if you find none it would probably be the case that the sensor itself needs to be replaced. It is called the Manifold Absolute Pressure (MAP) Sensor. You simply lift the tab on its plug to remove, then unscrew the screws that hold it to the manifold and put in a new one.

I take questions one at a time between 8am and 9pm CT and try to respond within 20 minutes. If I am shown as "MAXED OUT" try again at the 'top' of the hour as I may be answering another question or am otherwise busy. I specialize in Chrysler/Dodge/Plymouth cars, minivans, and SUV's for the model years 1982-2006 based upon my 50-year DIY experience, factory shop manuals and wiring diagrams. I offer fast repair advice to help you minimize repair costs by helping you diagnose and do it yourself. Problems with electronically controlled engines and transmissions as well as body wiring problems are my specialty. There are answers on file to more than fifteen thousand Chrysler questions at your finger tips: put a few key words in the "find" box (above) or click on "view past answers" for a chronological list of my q and a's. Don't use "Add to this answer" if you still have a question...ask it. I don't have manuals for truck or Jeep (except'04-'06).
