Promblem with engine light

use a scan tool to reset the ECM that put the light on

have you done a gearbox oil service?

Most likely cause is a O2 sensor on bank one ,try changing the rear one on the bank one

put oil bank in the crankcase. the dip stick shows this.
always check oil levers. every 2nd fill up.
all engine burn oil. All.

hi, I find a picture showing the bank 1 location for you, hoep help.

P1131 FORD - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank 1
This code is usually caused by a defective Oxygen sensor in cylinder bank one of your engine. Cylinder bank 1 is the bank of cylinders that contains number 1 engine cylinder.

I have a 03's sorento and this is quite a common promblem with these cars. First there has been a recall for these cars, if you havn't got it done, get it done, It's free of charge. The recall is the Camshaft Position Sensor. It will cause the car to run unstable, break and engine stall and causes accident and the engine light will come on. Secondly I had the same promblem that you were having, engine was shaking and sputtering and check engine light came on. What I found out is it is the EVAP Emission control system leak large bank 1 & bank 2 system too lean sensor problem. Had to take it to the shop to get the mass sensor replaced. It was a $900.oo + job, I recommend you taking it to the shop to get it diagnos to see what code it is giving you so you would know what exactly you are dealing with.

P0174 is a "generic" code, meaning it's the same meaning for all OBD II cars (every model year '96 and later).

It is system too lean (BANK 2)

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.

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. 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
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure

well the machine the mechanic used will tell him something like what bank side its on like bank 1 or bank 2 senors 1 .2 etc if you go to auto zone the scanner can tell what pos it is but some times the can be wrong if theres other promblems first

YOU MAY NEED TO CHANGE YOUR SPARKPLUGS AND PUT NEW ONES IN IT.
