Help With Throttle Body Issues

Hi guys, hoping you can help me. I've got 2008 saleen 302 e that keeps going into safe mode. I've been looking at the car over the last few days, it's had a new tps, I've cleaned the maf sensor and the throttle body, I've checked and cleaned the connections to the tps and to the tac. I went for a drive and pulled 3 codes p2111, p2112 and p2104. All these codes seem to point to the throttle actuator control. Apparently the return spring has been checked, are there any other checks I can do to the tac or would I have to buy a new throttle body complete? The car has only done about 12000 kms. Are there any checks that can be done to the pcm? Any ideas where I can go from here? Thanks!

Yes that's what I'm now thinking after a bit more research, it's a 55mm ford unit. I've checked the resistance on the throttle actuator control and I'm getting .3 ohms and I think it's meant to be above 1. I've ordered a throttle body so I'll let you know how I go!

Just to help anybody if they get this kind of issue I thought I'd put a response up. I ordered a new throttle body off eBay but unfortunately when I recieved it it was damaged, so I cut my losses and just fitted the throttle actuator control motor off the new one instead of changing the whole lot and it has been all good since, touch wood!
