Can you change the Temp sensor in a Toyota AFM?

This is my AFM intake temp sensor and my car is running like crap, got a code from the car confirming that the temp sensor is an issue. Whats involved in changing the sensor? Or can it be done at Toyota?

Thanks

The AFM can be disassembled and the IAT sensor pulled out.
You will need to cut the silicon seal that holds the plastic lid on and prize it out with a small screw driver.
From memory: You will also need to remove the wiper arm from the flap, the clock spring (that holds the flap closed and has a preset tension) and the circuit board. So make a good durable mark that shows the position of the clock spring before you take it apart, otherwise you'll have a hell of a time getting the thing sorted.
It's been ages since I had an AFM apart, but I'm pretty sure the IAT sensor's wires are soldered onto the main plug's pins, so you'll have to de-solder them and resolder the new(er) ones.
Reseal the lid with just about any silicon sealant.

Failing all of that, just get a good second hand AFM.

just find the 2 wires for the air temp sensor and wire and external sensor
u can get one of some 4ages that run a map sensor


what is the air flow u need?

Wouldnt you be better off leaving it there and putting a new one in the intake just after the AFM.
You could just re wire from stand alone ECU to it.
providing its is an aftermarket ECU.

Yeah I'm thinking I will wire in a new IAT sensor.. Finding one for the AFM then installing would be a massive PITA..

So what is my best option for a IAT sensor for a standard ECU? I don't have a standalone planned for install only an emanate.. Spose I will have to get a flange welded onto my intake pipe?

Try giving it a good clean 1st. May have dust particles stuck around it.
but if your running a std ECU, i recon looking for a replacement AFM would be the cheapest & easiest option.
