Code 38 means there is a problem with the O2 sensor for bank one sensor two. That is the sensor after the catalytic converter.
The sensor and circuit would need to be checked with a scanner.

Could be as simple as a popped fuse. Also check the wiring surrounding the sensor, could be exposed or frayed

Its not a P0300 it's P0032 and P0038


code p0032refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit high===causes --wiring short to positive--HO2S sensor--ECM
code p0038 refers to heated oxygen sensor(HO2S) 2 bank1 heater control --circuit high===causes --wiring shorted to positive --HO2S---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.

Mine is a P 0032 and P 0038


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
