SOURCE: codes p1153 -p1140 -p1133-p0174

P0174 Basically this means that an O2 sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.
P0140 Basically this means the an O2 sensor in Bank 1 detected a lean condition, same as mentioned above. Bank 1 is the side where cylinder #1 is.
In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling.

P1133 and P1153 indicate that the HO25 Sensor has gone bad. There the O2 sensor to the left and right bank at the exhaust manifold. When the engine first start's the PCM runs on a open loop and ignores the O2 readings till it reaches it's operating temperature. Once the operating temperature has been reached the diagnostic will only run once per ignition cycle and if the PCM detects a lesser then specified value, a DTC of P1133 or P1153 will come up.
Once the problem has been repaired, after 3 start cycle will reset the MIL light. If the O2 is just dirty and slow to heat up try cycling the ignition start 3 times and the light should go off if the O2 sensor does not fail.
Try cleaning the MAF first and see if the light comes off after a few ignition cycle, If the service light is still on you can always have Auto Zone clear the DTC codes and see if it comes back which then check the left and right bank wire harness to the O2 sensors. 
Good luck and hope this helps, keep me posted.

What are the probable causes of DTC P0174?


P0174 OBD-II Trouble Code

Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1. Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.


Symptoms

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.


Causes

A code P0174 may mean that one or more of the following has happened:

The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.

There could be a vacuum leak downstream of the MAF sensor.


Possible Solutions

Possible solutions include:

In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling

Inspect all vacuum and PCV hoses, replace if necessary

Check for a dirty fuel filter and proper fuel pressure

P0146 pd means pending code
Pending codes and DTCs? Posted on November 12, 2010 by fcrmaster
When reading codes from your vehicle the fault code reader may show them as pending codes or normal Diagnostic Trouble Codes (DTC).
Pending codes (also known as continuous monitor codes) will be registered when an intermittent fault occurs. If that fault does not happen again after x number of start/stop cycles, the ECU will erase the code from memory. If the fault is persistent it becomes a DTC.
If you have read pending codes it is advisable to check the codes again after a week or so. If there is no apparent problem with the vehicle it is safe to erase the codes too and check back. But always make a note of any fault codes with the date and mileage of a vehicle.
If the codes read include a DTC then you need to investigate further. This you can either do yourself or advise your garage. If, again, you don't see an apparent problem (depending n the severity of the code) with the vehicle you can note the codes down and erase them. Then check again after a week or a few days depending on how often the vehicle gets used. If a repair has been made (previous owner) the DTC may just not have been reset after the repair.
The other numbers behind the code 01/06 , 02/06, 03/06 , 05/06 ,04/06 These don't mean anything . cheap code reader .

DTC P0146 HO2S Circuit Insufficient Activity Bank 1 Sensor 3
DTC P0171 Fuel Trim System Lean Bank 1
DTC P0174 Fuel Trim System Lean Bank 2
Sorry but this is something you should take to a qualified repair shop that has a diagnostic tool that can view sensor scan data.

Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
