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

I have a 2004 dodge neon sxt, the check engine light is on and when i drive it the exhaust is loud and the car accelerates horrible. I get it up to 30 max and it takes a little while. Got it diagnosed and...


If u have an exhaust leak (loud sound) that will affect a lot of the sensor readings. The O2 sensors will not read properly either & set codes. If the leak is large enough u will lose power & the trans wont work properly either & set codes. Just because u have a code, doesn't mean the part is bad. Start w the basics. If there is an exhaust leak, fix that 1st & clear the codes.

Fault codes


P0449 - Evaporative Emission (EVAP) Vent Solenoid Control Circuit
P0481 - Cooling Fan Relay 2 Control Circuit
It is not uncommon for the canister vent solenoid to go out.More then likely this is the correction for this issue.The second problem could be addressed by verifying that the second fan is not coming on and whether or not the fan is receiving any power.Turning the a/c on normally forces the second fan to come on.If it does not a wiring diagram may be necessary to check different points for power.Would start at the relay itself to verify power is going to and through the relay. You can also swap an identical relay with the fan relay just to test if the relay itself is malfunctioning.If it works after that then you need a replacement relay for that circuit.If it still does not work you will need to find out where the power stops flowing in that circuit.
