How does the MAF sensor work on a Toyota Corolla?
The MAF sensor is tasked with measuring the amount of air entering the engine at any given RPM. The PCM ( P owertrain C ontrol M odule = Fuel Injection Computer) then uses this measurement of air flow to inject the correct amount of fuel. To get into more specifics: The MAF sensor informs the PCM the amount…
How do you replace a mass air flow sensor?
Use a ratchet and socket (or Torx bits) to remove the bolts securing the MAF sensor to the intake tube. Slide the MAF sensor out of its housing. Carefully remove the new sensor from the manufacturer packaging and slide into place in the air tube.
What does p0101 mean on the Toyota Corolla?
With the Toyota Corolla, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. We will cover exactly what that means and potential fixes for it below.
What are the symptoms of a failed mass air flow sensor?
The mass air flow sensor can also get dirty if the engine air filter is not changed on time, which results in the same symptoms as a failed sensor. The most common signs of a failing mass air flow sensor are poor engine performance, such as hesitation or stalling; lack of power; poor fuel economy; and difficulty starting.
What does the MAF sensor output at idle?
Here’s what it looks like on a multimeter: At an idle under 1000 RPM’s the MAF sensor outputs about 1.1 Volts DC. At about 1500 RPM’s the math signal output is about 1.2 Volts DC. Ask about 3000 RPM’s the MAF signal output is about 1.7 Volts DC.
What are the symptoms of a bad MAF sensor?
You’ll also see one or several of the following symptoms of a bad MAF sensor: P0102: Mass Air Flow (MAF) Sensor Circuit Low Input. P0103: Mass Air Flow (MAF) Sensor Circuit High Input.

Inside the maf sensor, there is a heated platinum wire exposed to the flow of intake air. By applying a specific current to the wire, the ecm heats this wire to a given temperature. The flow of incoming air cools the wire and an internal thermister, changing their resistance.
What does k & n mean for a corolla?
Some claim the K&N increases air flow without loss of protection; others say it is a waste of money, and at worst, that it lets more dirt into the engine. If the K&N does make a difference, it is at the highest rpms when airflow becomes critical. There are performance computers of varying utility and generally overstated claims, as well.
Are there any performance parts for the Toyota Corolla Hatchback?
We focus intensively on the E210 chassis and have dealt with enough Corolla Hatchback’s since it was first released in 2019. Browse through our catalog for a variety of performance parts including wheels, exhaust, intakes, and more.
What kind of air filter does a Toyota Corolla use?
They will attempt to find one that works best with the Corolla (i.e. Roots or Compressor Type made by Toyota, Vortec, Eaton, etc.). Their setup may require repositioning of the battery to the trunk and replacement of the air filter box with a aftermarket air intake system.
What happens if you clean the mass air flow sensor?
According to some Toyota forums, cleaning Mass Air Flow (MAF) Sensor can fix low idling. At about 85,000 miles my Corolla’s idle speed decreased from 700 to about 500rpm and felt like it was going to stall sometimes after the AC compressor kicked off.
What to do if your corolla has low idle?
[update 5/7/14] – Corolla now has 147k miles and the low idle issue returned worse than ever. This time cleaning the MAF sensor didn’t help, so I removed and cleaned the throttle body which was pretty dirty and that fixed the problem. Cleaning the Throttle Body:
