Ran pretty much all the test I could on it, came up with the following codes: (Same before and after clearing them and running the truck, codes came back after a drive.)

Now the CEL does NOT come on.... except the hard accell (P0238) and then it goes right back off, and the truck runs like a top.

So now, it's time to do some research and figure out what needs to be fixed. :doh:

I welcome any/all experience!

The black caused my #3 and #8 to fail. I installed the gray and it lowered #3 to passable

Interesting.... seems the exact opposite of the guy who ran the tests from the link above.

I will be running my own test when I get the Black International CPS.... Gonna run the AE test as well as track mileage differences.

Will post up when/if I ever get it done. I would LOVE to get rid of at least MOST of the codes.... preferable all. :doh:

Ok, so I learned I was doing the KOER Switch test wrong, so I did ALL of them again. Here was the results, second round:

1: (GEM/Central Timer)
B1483 Brake Petal Input Circut Failure
P1832 Transfer Case Differential Lock-up Solenoid Circut Failure.

2: (Hybrid Electronic Cluster)
U1262 SCP (J1850) Communication Bus Fault -
U1027 SCP (J1850) Invalid or Missing Data for Engine RPM -
B1352 Ignition Key-In Circut Failure -
C1710 RT Rear Center Sensor Circut Fault -
C1704 RT Rear Sensor Circut Fault.

KOER CCT: P0269, P0284. ( I believe to be related to Grey CPS)

KOEO: P0605 PCM ROM Test Fault, (From the Phoenix, right?) P1218 CID High. ( I believe to be related to Grey CPS)

KOEO Injector Buzz Test: P1218 CID High. ( I believe to be related to Grey CPS)

KOER: OK.

KOER GP: OK. :

KOER Switch: OK.
