SOURCE: Stalling Toyota Camry 2004

P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!

SOURCE: Car Stalls after at its own will with the P0102 Code

While the engine is running try tapping the mAF sensor with a wooden handle to see if that causes the engine to stumble or shut-off if it doesn't I would just clean it to see if that would solve your problem. You should also check and clean your throttle plate and throottle bore any carbon build up around the edges blocks off Idle air and can cause a stall condition.

SOURCE: I drive a 05chevy impala its pulling code P0102.

This is the Code for a mass Airflow circuit low. It can be the Mass Airflow component or the wiring to it. Do not spray without using an approved cleaner.

On some models this is a part that looks like a screen embedded in a holder. It works by reading the airflow down the intake venturi. It can be cleaned with an approved cleaner. If someone sprayed Gumout down the throttlebody, it may be ruined. It may look from the outside, like a carburetor spacer with wires and sits beneath the Air horn and throttle plates.

Since the onboard computer identified it as having a low circuit reading either the wires going to the part are not at full power or the part is not allowing full power flow.

You can check the connector for corrosion. You would need Specs for what the Resistance is suppose to be for the part or for the wiring going t the part.

Check out some Autoparts sites for photos and prices.

What is causing recurrent DTC P0102?


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 the wiring to the unit--plug connection

The truck stalled out when driving. Sounds like it wants to start, but won't fire. Codes found - P0410, P0128, P0141, P0102. Please help. Daughter's truck and she leaves for college in a few days.


code p0410 refers to secondary injection system--malfunction===causes wiring--air valve--air solenoid--- ECM
code p0141 refers to heated oxygen sensor-2 bank1-heater control -circuit malfunction===causes --wiring--oxygen sensor--ECM
code p0128 refers to coolant thermostat --coolant temp below thermostat regulating temperature==causes mechanical fault (thermostat stuck open)
code p0102 refers to mass air flow (MAF) sensor/ volume air flow (VAF) sensor low input===causes wiring short to ground--MAF/VAF sensor ECM

Where are the O2 sensors? I found one directly behing the spark plugs on the back.


The O2 sensor (2 on V engines) are in the exhaust system pipes before the catalytic converter, the next sensor is the efficiency monitor for the catalytic converter system it looks like a O2 sensor but performs a much different function as far as testing goes. The codes you have follow.

P0420 - Catalyst System Efficiency Below Threshold Bank 1
What does this mean? In most cases it means the catalytic converter is worn out and that is sensed by the catalyst monitor I spoke of earlier.

P0102 - Mass or Volume Air Flow Circuit Low Input
Faulty mass air flow sensor
- Dirty mass air flow sensor (located in the air intake hose to the engine from the air cleaner)
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks

2000 Monte Carlo SS- Stalls after running 5-15 minutes


Check the plug on the MAF.Wiggle it while its running......see if it stalls or jerks.
Or.......replace the MAF if the plug/wire connections are good to it.
The other 2 codes will not stall the engine.

Remember.....all cars run on used parts.
A good used MAF can be had a lot cheaper than new.

Trouble codes- What to do with them?


P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency, clean inside the of MAF sensor with spray brake clean, if code returns replace the Mass Airflow sensor (MAF)
P0440 - Evaporative Emission (EVAP) System,
poss loose or leaking gas cap
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature,
replace the thermostat, engine running cold
P0716 - Input Speed Sensor Circuit Intermittent, this is a problem with the VSS, vehicle speed sensor, replace it.
Clear all the codes after above repairs and drive a few days, then retest system for codes.
