Black smoke from exhaust,engine gets heated ,high fuel consumption

I would think the first step would be have the codes read and find out why it's running so rich.

If it is black smoke the engine is running too rich. There is too much fuel being sent to the cylinders so it doesn't burn the fuel cleanly. You'll get poor fuel consumption. Check the smoke doesn't have a blue tint to it as that is caused by burning oil.

P2270 - O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 2 Comments ' Add Yours
Possible causes
- Faulty Rear Heated Oxygen Sensor Bank 1
- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Exhaust gas leaks Help with this
When is the code detected?
The Powertrain Control Module (PCM) detected the HO2S12 sensor has reported a lean condition for an extended period during an intrusive test
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
P2270 Description
The Powertrain Control Module (PCM) supplies a voltage of about 450 mV between the HO2S high and low signal circuits. The oxygen sensor varies the voltage over a range from about 1,000 mV when the exhaust is rich, down through about 10 mV when the exhaust is lean.
The PCM monitors and stores the heated oxygen sensor (HO2S) voltage information. The PCMevaluates the HO2S voltage samples in order to determine the amount of time the HO2S voltage was out of range. The PCM compares the stored HO2S voltage samples taken within each sample period and determines if majority of the samples are out of the operating range.

Best I can tell this is a diesel truck? I know diesel, but
depending on age could be injectors, possibly Diesel injection pump hopefully not. The fuel is black? Someone is putting old engine lubricating oil in the fuel tank. It will increase the problem of black smoke. It may also have a bad smell because of the engine oil. If the turbo is not spinning properly (high pitched whine) the bearings may be bad and it's not getting enough air into the engine. This would also explain the smoke problem. Take it to a Diesel specialist!

P0152 P0152 - O2 Sensor Circuit High Voltage Bank 2 Sensor 1Possible causes - Faulty Front Heated Oxygen Sensor Bank 2
- Intake air leaks may be faulty
- Exhaust gas leaks
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
eplacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust P0152 Description The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

These codes, po 138 bank 1 sensor 2 shorted to voltage and code po158 means bank 2 sensor two shorted to voltage. these are the two rear oxygen sensors in the exhaust system. there two up frt and two in the rear, check the wiring on the two rear sensors, make sure that the wiring is not cut or stuck between metal. if the wiring is good then replace both rear sensors, when you get them ask for the left and right after the cat sensors. or bk1 s2 and bk2s2. after replacing them reset the computer. go to an auto parts sotre or if you have a code reader you can do it. hope this helps good day.
