E38 Silverado 2009 Gen 4 dtc p0606 in two diferente PCM

Hello. Im from Venezuela, and I had a troubles with a PCM E38 Silverado 2009 5.3l with A4 transmission. Downloaded original information with HP tuners and buy another PCM, second hand, but with thw same service number and put it the original PCM information. And after that the PCM always set p0606 and desable TAC. Try with other PCM and the same dtc and troubles with TAC.
Found another hpt files with the same part service number, motor and transmission and the same p0606 and the transmission knocks without dtc in TCM.
I appreciated your help.
Regards.

Make sure throttle tables are stock

All the tables are stock, cause the first PCM had hardware troubles and I don't modificate anything.

Is the vehicle completely stock? No modifications to it at all?

You cannot put a new (different) operating system into a used ECM using HP Tuners like that*.

*unless the used ECM was from the same year/make/model and already had a matching OS ID in it

Yes, its complete stock.

Hi blindsquirrel, what do you suggest that I can do now?

Post the HPtuners calibration file here.

And describe what the original troubles with the original PCM were please.

A log file, too. Two of the ECM segments (the ones HPT does not read or write, and will be left behind from the old OS) are only visible in a log, not in the tune.

Hi edcmat-l1. The original PCM always put dtc p0335 ckp sensor, and when it got hot it stopped accelerating, I reviewed everything related to it (oscilloscope, wires, original sensor, clean and change the TAC, new sparks, clean injectors, maf sensor) and the diagnostic was that the PCM had internal fail.
Found another and now I have this problem.

E38s are incredibly robust. The cause of your P0335 is not the PCM. I'd bet money on it and I'm not a gambling man. I'd put that PCM back in and figure out the cause of the P0335. If I were throwing parts at it I'd start with the sensor.

Thanks for the answer. The hpt file its ok?
We buy original new sensor, view all wires, ground, 12v, CAN lines, ckp wires and all its fine.
I have this truck for two months doing reviews, drives me crazy.

Excuse my ignorance, but this log file can be used to put the information in another PCM?

Not that it will help this specific configuration but there are several updates to your OS. Might want to just have it SPS flashed and retune.

No way, thanks for answer.

That was my next suggestion. SPS update.

Thank you.

There are things shown in a log file that do not exist in just the tune file. The tune file does not contain two of the eight segments. But, a log file will show the ID's of all eight segments, and then I can go put your VIN into the SPS lookup thing and find out if the two hidden segments for the electronic throttle are correct for the rest of the calibration.

If your used ECM was from anything other than the exact same year/make/model AND also started out as the same operating system ID, and you flashed your current tune into it using HP Tuners, then two of the eight segments are left over from whatever the ECM was programmed with in it's original vehicle. And if that is the case, *bang* P0606.

If you do not post a log file I can't look up the segment IDs, and nobody will ever be able to say for sure one way or the other if that is the cause of your current problem.

You know this is the case just because the problem was introduced with the replacement/used PCM. He did not replace the PCM for a P0606 problem.

Which leads to my next post, that he should put the original unit back in and fix the P0335 because it ain't the PCM.
