PLEASE HELP - serious 'safe mode' problems!!!!
Discussion
Hello all,
I have a 2005 VZ 6.0 LS2 Maloo and have been having problems with the car going into safe mode almost since I've owned it (over 2 years). No one can fix it and it is sending me insane hence the topic title!
These are the codes it is throwing up:
P2176 Throttle actuator
P2101 Throttle actuator
P1516 Throttle actuator
P0223 Throttle Posision Sensor 2 High imput
So far it has had the throttle body changed, the PCM changed and the accelerator pedal changed. After changing the these things the fault would go away for a while and then slowly come back going into safe mode more and more again. I'm guessing thats because the code would be cleared and the car wouldn't be looking for the code to start with. I have also looked at the loom and can see no visible damage. It goes into safe mode almost every time it is driven and happens during all types of weather and driving etc.
I am at my whits end with this. Someone PLEASE help

For some reason I cannot PM people? My browser won't load the screen properly. I have been speaking to paul at wortec and when he has got time it will be going to him. I am hoping that he will be able to fix it (it used to be their Ute), otherwise i won't know what to do!
Let Paul look 1st then 
Wiring loom?
Try Blair at Dynotorque?
If ECU and Throttle are changed as well as the connector that only leaves the loom.
Is the car standard? What about stuff like earths and battery connections.
Though you would have thought that would result in a wider range of errors.
Have you checked the throttle part number is right? GM changed throttles at one point and the two 90mm throttles are not the same even though they have the same connector and bolt pattern.
Sounds like nightmare. I hate intermittent issues. You have done well to handle it this long.
You "could" disable some of the codes so they dont trigger, but thats a very very bad last ditch thing to do.

So does the throttle blade track exactly what the pedal is telling it to do ?
Usually there are two sets of tracks in each, voltages of all 4 of these should match within a very small tolerance range throughout their entire movement.
And if changed sometimes these will all need their max/mins reset to the vehicle and ecu. ( and may require manual opening or closing of the blade to do so )
If they do not track properly, that's when errors could appear. But the faults causing the discrepancy could lie anywhere in the electrics. From base settings to components and any wiring in between.
Given the small amounts of error allowed one dodgy wire could be enough to make it start crying.

I have had a similar fault on my 05 Monaro VXR since i bought her 4 months ago.
Would go into safe mode randomly. Took it to Vauxhall who said the codes it was throwing were related to the throttle position sensor and this can be common on cars which have been sitting for long periods of time. They advised that it was probably damp wiring and it should dry up on its own over time.
That was a couple of months ago and while I havnt seen safe mode return the car will sometimes refuse to start, not even an attempt to turnover. This is accompanied by a "Service Vehicle Soon" message on the dash.
Most recently when she did finally roar into life the revs were bouncing around all over the place. She is booked in to have the codes read again. If the same codes appear again the wiring is being checked.
