So I said I was going to stay away from Voat for a week. Heard about your plight, resisting the urge to check other posts, replies, what have you.

As SlottingFloppies said, year, make, model is all good to know. This does look to be drive by wire.

However, I think you're going down the wrong path with this. With the air intake off the metering is bypassed it may not even start. I guess probably will in a closed loop mode, but no guarantees. Also, this plate is clearly cracked and it's open enough to start, I bet. Why would you expect the ECU to allow the plate to move before the engine is started?

If you are getting spark, shoot some starter fluid down the crack and see if it fires up. Or see if you can manually open the throttle with your finger. I don't know how those work, but there may also be a motor you can just power and set to a specific setting, although maybe it's a stepper and could be tricky, not sure.

I think you're down the wrong rabit hole. Pull codes off it, don't do this. It's an extremely modern vehicle if it's drive by wire. Or better yet, torch it, and get something with a proper cable throttle.

Motor sounded fine in the video, for the little bit I heard. Do you have spark? Fuel? Adequate compression?

Got it worked out... One of the coil wires had a sharp solder point that broke through and was grounding it and popping fuses. Had a mechanic come out and diagnose it for me. Cost $70, and some kapton tape.

Coil? The coil-on-plug or the coil in the throttle actuator? Glad you got to the root of the issue.

Im glad you got to the source of it. Like I did say, watch for codes for the cat efficiency. If you were shooting fuel into the cat, it may be necessary to replace.

I just went outside to check the exact code for the O2 sensor and it's gone. Now it's reporting all four coils have issues.

What is the likelihood that all four go bad on the same day at the same time? With no prior warning codes?

Sometimes an ECU can get confused and cutting the power to it by pulling fuses or even disconnecting the battery a few minutes to reboot it will help.

2009 Camry, I got it used so I don't know the complete history.

Why would you expect the ECU to allow the plate to move before the engine is started?

Not really a mechanic just figured an engine would need fire, fuel, and air to start.

If you are getting spark

I have new plugs but the original coils, is there an easy way to tell if I'm for sure getting a spark?

there may also be a motor

There is, it's a stepper motor, I'm worried without the specs I'd risk frying it since the coils would need to be energized in a three phase setup.

Pull codes off it, don't do this

Been doing that for month,. only codes relate to fuel being too rich. Dealership and everyone says it's the O2 sensor (what the code is for) which I replaced with a genuine one and still had the same codes. Been running pretty much fine for months with the fuel rich code till today.

EDIT: I had the dealership clean the fuel system months back.

torch it

There was flooding in my city today, I was half joking to the wife that we should just go push it in deep water and claim it.

Is it the mass air flow sensor?

Got spark? Are you SURE you got spark? Ok then, pour a little bit of gas in there and try to crank it. Just shove the valve open and pour some in there, a little bit, like less than 1/4 cup of gas, See if she fires and runs. I thought throttle body would only open with a vacuum. IDK.

Nope... Any easy way to test? New plugs but original coils as far as I know (bought her used)

Take a spark plug wire, off the spark plug. Stick a screwdriver, any normal metal screwdriver, and put inside the plug wire you just took off. Seriously, just pretend there is a screw inside that plug wire jacket, just place screw driver end in there. THEN on the metal screwdriver, the part of screwdriver shaft that is not covered by the plug wire jacket---take that screwdriver and lay it against any piece of metal, that is grounded, by your block. Crank car, see if spark flies in wire/screwdriver/ground. You should hear/see tickticktick tick. Theres your spark. OR your distro/coil is dead

YEAR MODEL MAKE OF CAR???

Not sure how the coils and plugs are set up on that engine, but you can usually pull a plug out of the engine, plug it into the end of the coil or wire, make sure the plug is grounded, crank the engine and watch for spark. Here's a video I quickly found pretty much showing the procedure

That's drive by wire.. well driven by motor. So chances are yes if the valve won't move, its seized internally. Carefully take it apart, un-seize and lubricate with white lithium grease in the gearing.

Had a drive by wire (it had a wire cable going to throttle body hehe) with a stuck closed idle air control valve. Just took it apart,reworked it, lightly sprayed with silicone spray and still runs great to this day!

Ah. The "maintenance free" parts of the car. Hopefully its not an expensive fix.

Could it be the fuel pump? The throttle body has some air going into it. If the ignition pack was bad, likely one cylinder would be misfiring.

I think most cars have a flood mode where you floor the gas pedal and try to start.

I don't think you can move the throttle body by hand, I think it may be attached to a stepper motor. I can hear air going in, sounds like maybe not getting fuel.

Wow, sounds like it was an ignition problem. Maybe that short caused the ECU to stop the ignition or all the current just shorted to ground.

Replaced the fuel pump a few months back when the symptoms initially started and that is what seemed to fix the issue. The only odd bit though was I had the code for the O2 sensor being biased rich and it's run OK for all this time now today it wont start. I also bought a new sensor and MAF sensor but the code would not go away.

Yea, it's a stepper, quite hard without power and I assume it'd be even worse when energized.

Also, check all fuses too.

What are the current OBDII codes? Toyotanation.com forums may be a good start for troubleshooting. Maybe YT as well.

As others have said with modern throttle by wire, your mass air flow sensor won't let the throttle body open if it isn't reading. It doesn't sound like you are getting spark, check your plugs/coils.

Well I've bought a new MAF sensor when the symptoms initially started. So I assume if its an issse there it'd be with the wires then.

Spark plugs are new but coils are the original ones. (2009)

I'm assuming with an 09 it has coil on plug ignition, and as far as I know those cannot be easily tested without specific equipment. If it isn't throwing any other codes I would have a mechanic test your coils, unless you already have the means to do so yourself.

2009 Camry...

New spark plugs, though original coils as far as I know. Bought it used.

Second I would check the fuel system. Probably starting with the fuel filter (assuming you can access it) then moving on to the fuel pump.

Already checked... Now this was the initial issue from months ago. First there is no fuel filter, it relies on the sock in the tank to do the filtering. I also purchased a new pump and sock which fixed things for the past few months. I undid the fuel hose and when I cranked the engine I got a nice geyser of fuel out of the assembly. So I would assume the pump is OK (especially since it was a genuine one and only a few months old).
