Hello, I had my car hooked up to a computer today and the codes P102, P0113, and P111 came up. The engine misses when driving down the road, and the car frequently dies when turning corners and idling. ...


P0113 Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50 C (-58 F). Possible causes are Open circuit in harness, Sensor signal short to power, Damaged Sensor, Improper harness connection, Damaged PCM

P0102 Mas Air Flow (MAF) Circuit Low Input, The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM) If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. Possible causes are MAF sensor disconnected, MAF circuit open to PCM, VPWRopen to MAFsensor, PWR GND open to MAF sensor, MAF RTN cirbuit open to PCM, MAF circuit shorted to GND, Intake air leak (near MAF sensor), A closed throttle indication, Damaged MAF sensor, Damaged PCM.

Hi! The MAF (mass air flow) sensor is surely faulty. The MAF has big contribution on the engine performance specially on the idling an vacuum supply. If the MAF is faulty the rpm will drop eratically or die. Regarding the overheating problem, you may want to check the radiator blower for it may be tripping that sometimes it works and sometimes won't. This can be a good cause. Hope this helps and thank you for using FixYa!

My 1998 volvo s70 go died when idle at stop i


I'm having the same problem. At first I thought it was bad fuel so I replaced the fuel filter to no avail. Then I cleaned the Mass Air Flow sensor which also didn't work. Is your check engine light on?

Find your air mass flow sensor in the stiff collar of the air ducting immediately after the air filter. Have the engine running and disconnect the plug to the MAF. If this makes the car run evenly again you need to replace the broken MAF. The misfire on plug 4 I think is a downstream event of the MAF not sending the right info to the ECU and consequently not providing the right fuel / air mix to the engine

My 2000 ford focus has codes p0102 and p0113 whats that and what could it be?


P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
Damaged PCM
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

I have a 1997 Ford Explorer. Check engine light comes on after 20 miles. After reseting the check engine light. The codes that come up are P 171 & P174. I already changed out the Maf sensor. But cant get...


Here is a list of possible causes, hope this helps.


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.

Possible Causes onepx.gif Setting Conditions onepx.gif onepx.gif onepx.gif onepx.gif
  • Air leaks after the MAF sensor, or leaks in the PCV system
  • Vehicle running out of fuel or engine oil dip stick not seated
  • EGR valve gasket is damaged or leaking around the gasket
  • Exhaust leaks before or near where the HO2S is mounted
  • Fuel injector(s) not supplying enough fuel
  • Fuel system not supplying enough fuel during high fuel demand conditions (e.g., the fuel pump may not supply enough fuel)
  • MAF sensor is dirty (can cause PCM to underestimate airflow)
  • Intake gasket leak

2004 gmc safari - engine light on - veh. will only go 60km/h then dies - computor check claims maf - changed but change in veh.


PLease have the battery checked and if that checks out ok I would lean towards a O2 sensor.

Check Engine light came on (2001 E320 with just 20,000 miles on it). After connecting the scanner, the code showed P0 170 and P0 173 which I was told was a Mass Air Flow (MAF) sensor problem. I...


Those codes do appear to deal with the mass airflow sensor. The MAF sensor is probably the "hot wire" type where a thin wire is suspended inside the body of the sensor and is heated with electrical current. The amount of air passing over the wire is directly proportional to the resistance of the wire and that resistance data is calculated. The MAF sensor, by itself, cannot determine the air mass supplied to the intake plenum. One or more other sensors are used in conjunction to equate these values. The oxygen sensor(s), Manifold Absolute Pressure (MAP) sensor, the Intake Air Temperature (IAT) sensors may all play a part in this fault reading.

There are reliable methods to test the MAF sensor. One well takled about method is to tap the MAF sharply with a screwdriver handle while the engine is running. If the engine dies, the MAF is faulty. This can detect a physical defect in the wire and a few other things but do do assume that, after repeated blows to the MAF with your dead blow hammer for good measure, that the MAF is at 100%. I will research some text on testing these sensors on that particular model and post links to any information and diagnostic data I find.
