03 GTX DI PTO and MAG TPS OUT OF RANGE
Does anyone think this may cause a failure where you loose compression? I have about 24 of the PTO sensor and 150 of the MAG sensor out of range faults.

These sensors not working properly can cause you to fry a motor, yes. These sensors determine the fuel mapping, chances are it ran lean and cooked the cylinders causing low compression.

That is what I was afraid of. Thanks for the input. I now have begun the procedure of diagnosis on these sensors. I have 2 extras. I want to swap them out after I run it on the trailer for a bit. See if it throws a code again.

If it's really low on compression you know you will only be doing further damage to the engine right? You might get away with a top end if you don't run it till it scatters...
How low is the compression?

The compression on the old engine was 25 and 100. I replaced the engine, cleared the codes, and fired it back up after going through the usual precautions. It fired and I ran it for 5 seconds. It coded on both TPS sensors. I replaced both of them fired it back up. Now no codes and I plan on running it on the hose for a while in the driveway. I also will conduct a fuel pressure test as it wont rev up.

Started it in the driveway on the hose.
P1102 TPS, PTO TPI_1_ADAP Throttle position adaption failure
Yes No Full reset. Key off and on
No initialization after throttle body or ECU changes throttle idle. Stop drifted.
Check cable adjustment. Check Idle stop for wear. Check throttle angles at idle.

P1102 again. I am going to switch them and see if I get a fault on the PTO side.

I ran the candoo, wrote the cleared codes and reset TPS back to the machine. Started on the hose 4 min or so, so far so good. No codes, no faults. Test drive today!
