If the MAF sensor is bad then you need to replace it. 1102 does relate to the MAF sensor. It can also be a bad O2 sensor.

P0102 code 2009 chevy malibu


code p 0102 refers to mass air flow(MAF) sensor /volume air flow (VAF) sensor --low input===causes --wiring short to ground ---MAF/VAF sensor ---ECM
check wiring for insulation problems or broken connections
replace the MAF sensor

Code P1102 - States pending fault.


P1102 for the Mazda is :Mass Airflow Sensor Signal Inconsistent with Throttle Position Sensor. The Mass Airflow Sensor is located in the housing before the Throttle body; it reads the air coming into the system....the Throttle Position Sensor tell the ECU how much throttle you are asking for....I think that the in-air flow and the throttle are not getting the same answer; example would be that you are driving fifty miles an hour and either the MAS or the TPS are not seeing (receiving) this information. Note; most times the MAS is at fault, it can be cleaned but be very careful.

Replaced the MAF. Still have the P0113 code. Car runs fine. Cannot find another intake air temperature sensor anywhere on the vehicle! Where is it?


code p0113 does not refer to a MAF sensor so replacing that was a waste of money=== It refers to intake air temperature (IAT) sensor---circuit malfunction====causes --wiring open circuit/short circuit to positive--wiring short circuit to ground---ground wire defective---IAT sensor---ECM.
Replace the IAT and check the wiring is in good condition and the connectors are clean and tight.

99 Audi A4 quarto, keep having to replace same coil pack and code p0102 but changed the MAF. My last guess is the wiring has gone bad, but I don't know how to fix it or even where to start.


code p0102 refers to mass air flow (MAF) sensor/volume (VAF) sensor-low input===causes --wiring short to ground---MAF/VAF sensor--- ECM Replace the sensors and check for a wire shorting across to the earth pin. Code po102 has no reference to coil packs but check that the wiring to the coil has not been damaged when removing for replacement.

How do i fix trouble code 122 and 102


Throttle position sensor and maf sensor are displayed for these codes.Trouble Code: P0122

TP Sensor Circuit Low Input

Possible Causes:


TP sensor signal circuit is shorted to sensor ground.TP sensor signal circuit is open (except 1996-1998 models).TP sensor VREF circuit is open between sensor and PCM.TP sensor is damaged or it failed (it may be shorted).PCM is damaged or has failed.Trouble Code: P0102

MAF Sensor Circuit Low Frequency

Possible Causes:


MAF sensor element hot wire contaminated or the sensor failed.MAF sensor signal shorted to ground or ground circuit problem.MAF sensor wiring routed close to the ignition wires, generator, solenoids or electric motors.PCM has failed.Click on link to view how to replace.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f80cb3c01

Where is the fuse located for the secondary air pump for the 2000 Ford Mustang 3.8


Hi there:I suggest to check on the Power Distribution Box, that is located in the engine compartment.The power distribution box contains high-current fuses that protect your vehicle's main electrical systems from overloads.

DTC P0171 - System Too Lean (Bank 1)This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.


A code P0171 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 may 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 cracked vacuum or PCV line/connection
  • Faulty or stuck open PCV valve
  • Failed or faulty oxygen sensor (bank 1, sensor 1)
  • Sticking/plugged or failed fuel injector
  • Low fuel pressure (possible plugged/dirty fuel filter!)
  • Exhaust leak between engine and first oxygen sensor


Possible solutions, a lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include:
  • Clean the MAF sensor. 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/repair as required
  • Inspect all hoses and connections in the air intake system
  • Inspect and/or test the intake manifold gaskets for leakage
  • Check for a dirty fuel filter and proper fuel pressure
  • Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool
  • If you have access, you may want to run a smoke test


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Car running on limp mode



  • Your MAF sensor is malfunctioning. You can try to unplug it and clean the contacts and plug it back in and see if that works. If not simply replace the MAF sensor. This is what causes limp mode in Nissan's.
  • You will probably have a P1102 code which will tell you "Traction Control Solenoid" which amounts to your MAF sensor is in range but lower than expected. Your vehicle is probably bogging out at RPM's that it normally functions fine at.
  • After you clean the contacts make sure to have Auto Zone reset the code for you. If your car goes into limp mode again just throw in a new MAF sensor and again have the computer reset at Auto zone (free).

  • Hope this helps and thank you for using FixYa.

Mass air and volume air low imput circutbank a1. changed mass air sensor and air filter. And the 10amp fuse for engin that controls the tak keeps blowing. where is the short.


Hopefully it will be in the circuit itself, try this install the fues with the MAF disconnected does the scan tool say high input,(how did you know it was low input),dont start it it does the scan tool show 5vlt ? Either of this way you have a grounded wire from power distirbution that goes to the MAF this wire is from power the distribution box or (engine fuse box goes that goes to MAF and is grounded . This is why you Ignition fuse blows to option fix and find this short or have someone who know how and is qualified to subsituted for another wire from Ignition to MAF ignition circuit at the power juction box (engine fuse box)

There is no p01001, it's either p0100, or p0101.
Anyway, it's the mass air flow sensor that's bad. The p0171 and p0174 is a lean condition on bank 1 and bank 2, which are the oxygen sensors. Change the mass air flow sensor and that should take care of the p0171 and 74 codes.
The mass air flow sensor can cause the 02 sensors to read lean.
The u1301, is a class 2 circuit short to battery. That, you have to test wires to find with a voltmeter/continuity tester.
I would try and find that short before changing the flow sensor, you don't need the new one shorting out, they are not that cheap.
