Here's a link to your P0038 code and the causes. P0038 Dodge O2 Sensor 1 2 Heater Circuit High

code p0032refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit high===causes --wiring short to positive--HO2S sensor--ECM

It is most important that when installing /removing the sensor that the correct tool is used to prevent damage to the wiring for the sensors. Severely twisting the wires during installation/ removal will result in the causes for failure listed.

upstream and downstream oxygen sensor heater voltages are too high, possible causes are
- bad o2 sensors
- shorted o2 wiring
- bad pcm
clear codes and determine if codes are hard(current)
if they are, unplug sensors, clear codes and re-scan to see if p0032 and p0038 appear.(there will be 2 to 4 other codes generated)if p0032 and p0038 are gone from the list, change both o2 sensors.
if p0032 and p0038 are still in the list, it is either wiring or pcm issue, use a meter to check for short from o2 connector to ground, with pcm unplugged..
Good luck, Rob

if u have a code reader there is a code look up option on all obd readers go to the code lookup type in your code and it will give u a description of code if u don't have a scanner any auto parts store will scan for free.

Tune up? coils, wires, fuel filter.

P0038 typically indicates O2 sensor failure or possible grounding out if the cabling to it has failed. Start with that as it is easier to replace than all the plugs/coils etc. Reset the code and cross your fingers.
