What is a po102 code?
P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What does mass or volume air flow a circuit low?
P0102 – Mass or Volume Air Flow Circuit Low Input. P0102 is an OBDII trouble code indicating that the mass air flow sensor (MAF) is reporting inaccurate values. A MAF that is reading too low will then result in not enough fuel being injected, and as a result the engine would be operating in a lean condition.
What is the code for a bad mass air flow sensor?
The code P0101 means that the signal from the mass air flow sensor (MAF) is out of expected range. The MAF sensor is installed in the engine intake, right after the air filter. If the signal from the MAF sensor is lower or higher than expected, the ECM detects a fault and stores the code P0101 in its memory.
Can u drive without a MAF sensor?
You can drive your car a bit and see if it runs correctly with the sensor disconnected. That is because even though your car can run without the mass airflow sensor, you shouldn’t do it for long periods.
What to do if your Toyota has a p0102 code?
Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor. The cost to diagnose the P0102 TOYOTA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
What does p0102 mean on the MAF sensor?
The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner’s manual for your specific car). P0102 Symptoms
What to do if your Toyota code comes back?
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor. The cost to diagnose the P0102 TOYOTA code is 1.0 hour of labor.
What are the symptoms of a p0102 low OBD code?
Symptoms of a P0102 code may include: 1 Malfunction indicator lamp (MIL) illumination (a.k.a. check engine light). 2 Rough running engine. 3 Black smoke from tail pipe. 4 Stalling. 5 Engine hard start or stalling after it starts. 6 (more items)
