Limp mode, codes read, results inside

[timps]

The car went in to limp mode last night with the electrical fault light on (the one with the wavy line) and eml on. The electrical light goes off when car is turned on and off but eml stays on. It did this before around 2 months ago and a quick clean of the TB sorted the problem. I tried this again today and it made no difference so went and got codes read. The results are below

Now the throttle body makes an awful noise when the ignition is on, sounds almost like a modem when connecting to internet, so it may just be a case of a replacement but want to make sure before i go out and buy one. Any ideas?

Thanks

smells like tb, but could also be loom related. check the loom for damages first and have a look if the plug on the tb is corroded. Anyone near Halifax who could lend this guy a tb?

plug on the tb is perfect, will check the loom again incase i missed something from before. Lending a tb is not a problem, its because the light may come on after 5 mins or after a week so would need it for a while. Think ill just buy a new one and hope for the best

The noise form the throttle body is normal.

im quite sure it isnt the normal noise. This is the closest i can find to the noise i can hear, not quite as bad as in the video but getting there

Pedal probably. Could do with clip really thats a bit vague, doesn't say whether its the pedal signal or the readback from the body.

Noise from the throttle with the ignition on is totally normal.

Bit of an update, ive found, if i keep the car above 3k revs, it will not go in to limp mode. It is only when the revs drop to say below 2k when slowing down for a junction that it comes on. Any more ideas or would you still say pedal or TB. Thanks

Throttle position sensor would be where I'd start as they're cheap and commonly go.

As said though you need a clip tbh

Throttle body is most likely, especially as removing and cleaning it before made a difference.
