7MGTE Fuel Cut at 2700rpm
- Thread starter kaiser

You can't have overboost fuel cut without the 34. When it is calculated that fuel needs to be shut off, 34 is automatically triggered. Along with the MIL as the car stumbles. Considering all the threads on this subject over the years, I would be suprised to find that the MIL did not illuminate when the PCM was giving an open circuit to the ground.

I am not making boost at all, I cannot make it past 2700 rpm without hitting fuel cut. I severely doubt it is a boost leak or I would be running lean and I am running at 10afr

You probably want to read these two JetJock's posts:
Stock ECU Modes: Back Up
Stock ECU Modes: Fail Safe
(there may be also on this board, I just searched google)

Well, no it isn't. There is 3000rpm fuel cut that occurs when code 31 is set (AFM fault). There is also a 3000 rpm fuel cut if the ecu thinks you have been abusing the engine, but I doubt that is the case here.
Jon, doesn't backup mode enrich like a pig and won't allow mid/high revs?
It is my understanding from the above link I posted..

He doesn't have a boost leak. Unless he can not count 3 then 4 flashes. A boost leak is a vacuum leak when not under a heavy load.
Exhaust Not Plugged. It just has a 3" Divorced Down Pipe with no exhaust from there on.
JetJock This thread is still alive because I am out of town working and have limited time to work on the truck when I am back. Add that to the fact the Supra parts are non existent in North Eastern Ontario and most importantly my truck is not running. You have been very informative so far, and I appreciate the spoon feeding.

kaiser - buy parts from rockauto.com - not performance parts, but cheaper than buying local, even after shipping & duty.
Huh? My input has been very limited because I knew from the beginning this thread would be a lost cause. The signs are all there.

Damn, thanks Rollus for posting those, and a big thankyou to JetJock for taking the time to write them.
They shed alot of light on the TCCS for me.
You're welcome supraguy 
To the OP:
You are perhaps in backup mode, and if I understand corrctly, this back up mode won't even light the MIL..

It won't Monsewer but I seriously doubt that's his problem. It's very likely something far simpler. Unfortunately the OP's lack of understanding about how the system works coupled with the poor diagnostic info he's supplying isn't helping matters.

Hey jet jock. I would be glad to provide you with any diagnostic information that would help but unfortunatly I am new to this and do not claim to be a professional. I have rag through wires and i have tried to follow along with the diagnostic procedure outlined in the tsrm.
I did read thos two articles and found them extremely helpful and well wrafter I try a new afm sensor I will try using my back up ecu. Great suggestions everyone! Thank you all taking the time!
