wrench on display

[xyzabc33]

I've had this hAppen to me 3 times already. Any ideas would be appreciated.

I,have a 06 EB with 4.6. Went start it this morning and it was hard to start. When I did start the check engine light came on and the wrench on the display. When you press the accelerator the rpms don'give at all. I can let it set.for 15 minutes and it will work again. Full tank, dry gas etc.

Owners manual has brief descriptions of warning lights and chimes starting on page 12.

I work in a autoparts store. Scanned it and nothing stored. I read the manual and it says its a powertrain problem. But I have been reading and alot of the symptoms are the same as a throttle body problem.

what scantool are you using because not all scan tools can read all modules with these new CANbuses

I went to lunch and it happened to me in the parking lot. Was able to get codes this time.

p0121
p022
p2072
p2104
p2111
p2112

all reference the throttle position sensor and the like.

Gonna try cleaning the throttle body first and see if that helps. If not, Anyone know a good aftermarket replacement? I can get one through work, but if there is a better flow version avaliable, I would look at the avenue.

Best wishes. Throttle sends signal to PCM. PCM sends motor command to ETB. TPS sends position signal for PCM to compare. Sometimes one of these is bad, or just the butterfly valve dirty in ETB.
Clean MAF sensor and ETB first. If not fixed, second choice is to replace TPS (a pain because locktite on screws...special procedure). However, next step is to replace ETB and most come with TPS. Remove battery cable when disconnecting any connector. May have to reset PCM and do a re-learn.

I did more work, and here is what I found:
I also had Limp Mode problems that got worse over a period of a week or two. P2104, P2111, & P2112. After reading quite a bit, I replaced the TPS but no better at all. Finally got so bad that as soon as I touched the throttle it would show the wrench and limp mode.
Had already cleaned the MFS and the ETB and they were very clean. Checked the connectors and wiring and everything seemed fine.
Frustrating.
So read a bunch more and decided I was going to have to spend the money and get a new ETB next... But didn't want to spend that much money.
As a final option, I took the ETB drive apart and found the DC motor had very dirty armatures. It was tricky, but gently pulled the brushes back and put 600 grit sandpaper in front of them in a very tiny piece. Using the brushes, I pressed the sandpaper against the Armature gently and twisted and twisted the DC motor spindle. Took three pieces of sandpaper to get most of the black off the Armature. This was rather tedious and you have to be gentle. Also tricky to get it all back together, but after PCM reset, reassembly and starting the truck, and going through learning procedure, it ran perfect. Yay!
Just wanted to pass this on to those of you that know much more than I do. Hope it may help you understand why the error codes trip and the engine becomes useless.
