Testing P0113 error

 

I found this video on testing both functions of the MAF sensor (we are testing the seciond part, the IAT part.

You will need the correct tool to remove the sensor, in my case it was a Philips screwdriver and a multimeter to test the function of the temperature side of the sensor, you will also need to understand how to use and understand readings from your multimeter 

1. remover the plug for the sensor.
2. Remove the screws 
3. gently wiggle the sensor and it will come out 
4. lay the sensor on a clean surface 
5. get the multimeter and set it up to read K ohms

information on testing from the above has been snipped out 

On measuring the sensor with the ambient temp that the sensor is in is at 17 degrees, I got 1.92k ohm (this is working fine at this temperature), it doesn't mean the sensor isn't failing at higher temps.

I cleared the error code and switched the ignition off and started the car, it hasn't come back yet, I will take the car for a drive and see if it comes back 

Ravioli is not well!

On my drive home from our holiday, my car decided it wanted to drop out of cruise control and the VSC warning and 4wd disabled as well as the engine light came on!!!!

At the time, I had no way to test the car, but it drove fine and had no limp mode, I drove the car home and plugged in to it and found error p0113.

Fault meaning and remedy:

 What does this mean? 

P0113 TOYOTA code possible causes Dirty air filter Faulty Intake Air Temperature (IAT) Sensor (Part of the Mass Air Flow [MAF] Sensor) Intake Air Temperature sensor harness is open or shorted Intake Air Temperature sensor circuit poor electrical connection Faulty Engine Control Module (ECM) 

How do I fix code P0113 TOYOTA code? 

Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

This is what my sensor looked like, fixed by 2 screws on the rear of the air filter box as this sensor has two functions, it is known as the MAF sensor.

Firstly I checked the air filter I replaced in March April time and check the box isn't full of leaves.

Secondly, I checked the connector to the sensor and unplugged and pulled the wires gently, as well as checking the pins and the connectors for corrosion.

Thirdly, I removed the sensor to check there was no visible fault.

I found no big issue when with the above, so next was to try and find any way to test the IAT of the sensor and at the time I came up with nothing, but I found a comparable l MAF sensor for £11.94p, so I ordered it.
