Check the mass air flow sensor. Unplug it, then try to start the engine. If it starts and runs ok replace the sensor. Make sure the wiring is good to the sensor, The wires may break inside the covering near the connector ends.

2001 Buick la sabre Code p0171 and p0102 I have replaced every thing but the Maf and erg


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

I keep getting all these cods p0102 p1120 p1220 p1221 p1514 p1516 p0102 p1120


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

I took my car to have it checked at Autozone. The results were OEM Number to Cross: P0102. What is wrong with my car?


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.

1999 GMC Jimmy SLT Engine light is staying on. Jimy was surging. losing power and regaining - unable to maintan speed. Dealer replaced mass air flow sensor with change up sensor and cleared DTC'S. Road...


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.

The antilock breaks on my 2001 toyota sienna come on even when making normal stops on flat dry roads. what is causing this ?


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.

Driving down road truck cuts off


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.
