What is code p017.2 for a 2002 dodge caravan - 1999 Dodge Grand Caravan

This is the closest I've come to the code you are looking for. I searched all Dodge codes and didn't see any with a "point 2" but I found code P0172. According to EngineCodes.com your fuel mixture is probably too rich. This is what the site had to say:

Possible Causes for this Code:
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor

P0172 Dodge Code Description:

With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).
