P1005 is model specific, Dodge is a problem with the manifold tuning valve.
Code 158 and 157 are for a problem with the O2 sensor for bank two after the catalytic converter.
Code 128 is for a problem with the thermostat or the engine is not reaching normal temp.
The O2 sensor codes could be caused from the manifold valve or they could be caused by a faulty O2 sensor.
I would start with the coolant temp problem and work back.
SOURCE: had code p0058 come up,
This vehicle is equiped with 2 O2 sensors 1 is before the Cat converter and 1 after the Cat converter this code is for the 1 after the Cat converter or the most rear sensor not the first 1 change the farthest one from the engine and your problem should be solved.
SOURCE: indicator light looks like tire icon just above check engine ligh
low tire pressure...there should be a reset procedure in the manual
SOURCE: 2007 Grand Caravan check engine light no code
o2 sensors get dirty and trip the check engine light they get carbon buildup on them.

this is an obd2 trouble code table, it can help you understand the meaning of code.
for p0157 you can try this:
It's always good to start with checking for air leaks in the exhaust manifold and in the exhaust pipes. Fix these first.
With KOER (Key on engine running) use a scan tool or a voltmeter check the o2 sensor signal voltage with engine warm. You may have to increase the RPM to a fast idle to check the voltage of the bank 2,2 sensor. If it's voltage is stuck low (less than 0.5 volts may not be enough to set the code, but it depends on the vehicle) and you don't have any other o2 sensor codes present in the PCM, then it's a good bet that the sensor is bad. If the voltage isn't stuck low and the o2 sensor seems to be operating fine, it's likely sticking low intermittently. This often turns out to be the sensor. In either case, replacing the sensor can be an effective way to diagnose the problem. But it can also be an expensive diagnostic tool, especially if it turns out to be a wiring issue, instead of a sensor.
So, if you're interested in knowing for sure what the problem is before spending unnecessarily, then perform the following: 1. Turn off the engine and unplug the 2,2 o2 sensor connector. Inspect for corrosion, etc. Repair as necessary. Make sure that there is battery voltage present and ground present for the o2 sensor heater. If there isn't, then diagnose that first then retest. The o2 sensor depends on the heater to warm it up so it can start working quicker. If the heater element is bad or there isn't the proper voltage supplying it, the sensor may set this code. Usually heater problems have codes associated with them, too. If you find there is no battery voltage feeding the o2 sensor use the associated code to diagnose that. If you find the heater element bad, replace the sensor.
If the heater element checks out then, using a jumper wire, supply a chassis ground to the o2 sensor connector(PCM side) ground circuit. Now observe the scan tool bank 2,2 o2 sensor reading. If it is now at about a half a volt then replace the o2 sensor. If, after supplying a ground to the unplugged PCM side of the o2 sensor connector, the voltage reading doesn't change then check the harness for short to ground. Check for harness making contact with exhaust components. Check pins for damage, and for moisture. Repair as necessary. If you can find no harness problems, then the PCM may be at fault.
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
A code P0128 may mean that one or more of the following has happened:
Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
