Vehicle cut off going down the road. The scan

did you clear all codes after fitting everything the read for codes again

try cleaning the plug in contacts of the maf
and cleaning the maf itself
Mass Air Flow (MAF) Circuit Low Input
https://www.obd-codes.com/p0102

A code P0102 may mean that one or more of the following has
happened:
The MAF may be disconnected, or a wiring connection may be bad The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF). The MAF sensor may be faulty The vehicle computer may be faulty (very rare)

if you replaced.02 sensor.it should not throw a pO171code

egr valve ...can be tested ...even cleaned

Hi Robert, It would help us to know which vehicle as the codes very well may be vehicle specific.Ford seem to have codes of that numerical range, so I'm assuming your vehicle is made by Ford.
P1120 refers to the Air flow sensor. P1120 the throttle position sensor. 1220 Series Throttle Control Fault (probably related to the TPS) 1221 Refers to the high speed fuel pump relay having been activated. 1516 Intake manifold runner input error. Cannot find P1514 Hope this is helpful. I suggest sorting out the air flow sensor and the throttle position sensor to begin with and that may sort out the other defects. Very often one sensor giving an error reading will trigger others. Regards John

P0102 refers to the MAF (Mass Air Flow) sensor. It may be dirty, faulty, or have a bad connection. Possible remedies are:

• Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
• Inspect for any air leaks near the MAF sensor.
• Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
• Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
• Replace the MAF sensor.

What kind of a dealer are you going to . If what you are saying is correct the MIL light is on then what you need to do is find out what code is making the light come on it will have a # P0 - - - the MAF or mass air flow sensor on this vehicle would be P0102 or P0103 its the first sensor and a main sensor that would create a lot of driveably problems but the code would be there . How the dealer got from the maf to replaceing the transmission and ovesely that was not the problem and now it telling you you need a new alternator is eighter criminal or complete incompants. Find out what the code is and i will tell you what is wrong with it and don't go back to that dealer you didn't need any of these parts . Any auto parts store will read these codes at no charge for you this is why the OBD 11 system is there and is standard on all vehicles with a few exceptions in the us but not your vehicle and regulated by the federial goverment . I work on vehicles and owen one a blazer my self witch is the same thing as a jimmy. And you are getting riped off pier_j

Sounds like you have a fuel issue. It could be a fuel pump cutting in and out. It could be fuel pressure regulator, or an injector not spraying correct. I think it's time to find an honest educated repairman.

you are facing the protocol problem, imports uses a diferent CAN interface, if your scan tool is not capable wont read it. try going to an auto part they're scan it for free

this vehicle most likely has a mass air flow sensor it may have got accidently unplugged or the air tube from mass airflow to engine is not connected well or it could be that you have indeed a bad mass air flow sensor they do make a special cleaner that you may want to try before purchasing a mass air flow sensor or purchasing one from salvage yard the symptoms you describe would be created by a bad massair flowsensor

For some reason the ABS module believes one of your four tires is locked up and skidding.
Do you have any warning lights that are coming on? I would suggest you take the vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan the vehicle for trouble codes. Write the codes down and respond back to this reply and we can get started diagnosing.
Chances are you have a wheel speed sensor that is registering "0" mph when the brake is applied, that is usually the most common problem with your type of ABS activation.
Good luck, let me know when you have the codes.
Regards,

Your vehicle may be involved in recall 07S57 for camshaft postion sensor replacement. It will cause these symptoms you described.

Look on the left side task bar, pick recalls and insert your complete VIN number to see if your vehicle is involved.

I had the same thing happen in my 1985 Nissan Pickup. It would just cut off. It was the fuel pump regulator switch on my vehicle. About a $50 item from autozone.
