2008 6.0 Van

[MikeOD]

Does anyone have a stock 2008 6.0 van file they can upload? Either a GMC or Chevy. I've got a 2008 Silverado 6.0 tune to compare to, but I'm running into a P1516 code that I believe has to do with an incorrect throttle map for the TAC in this PCM.

I might be able to get it in bin format. That be helpful?

Yeah, BIN format would be fine.

The file you posted isn't stock. Looks like the throttle map is though?

Mike,
I got hold of my buddies 07 6.0 2500HD It is an ly6 with a 6l90. tried to save as a bin file. Got it in .cal .PM email address it wont let me post it.

I might be able to get an 08 van calibration if that would help.

Circuit/System Description
The engine control module (ECM) is the control center for the throttle actuator control (TAC) system. The ECM determines the drivers intent and then calculates the appropriate throttle response. The ECM achieves throttle positioning by providing a pulse width modulated voltage to the TAC motor. The TAC system uses the following circuits:

Motor control 1
Motor control 2
Two processors are also used to monitor the TAC system data. Both processors are located within the ECM. Both processors monitor each other's data to verify that the indicated throttle position is correct.

Conditions for Running the DTC
P1516 and P2101
The ignition is ON.
The ignition voltage is more than 8 volts.
The system is not in the Battery Save mode.
The engine is running.
DTC P0068 is not set.
DTC P1516 and P2101 run continuously when the above conditions are met.
P2119
The ignition is ON.
The vehicle speed is 0 km/h (0 mph).
The ignition 1 voltage is more than 10 volts.
DTC P2119 runs once per ignition cycle when the above conditions are met for more than 1 second.
P2176
The ignition is ON.
DTCs P0120, P0122, P0123, P0220, P0222, P0223 are not set.
DTC P2176 runs once per key cycle.
Conditions for Setting the DTC
P1516

The indicated throttle position does not match the predicted throttle position for more than 0.5 second.

P2101

The indicated throttle position does not match the predicted throttle position for more than 0.3 second.

P2119

The ECM determines that the throttle valve did not return to the rest position within 720 milliseconds.

P2176

The difference between the predicted and the actual throttle position is more than a calibrated amount for more than 1.5 seconds.

Action Taken When the DTC Sets
P1516, P2101, and P2176
DTCs P1516, P2101, and P2176 are Type A DTCs.
The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
The control module commands the TAC system to operate in the Reduced Engine Power mode.
A message center or an indicator displays Reduced Engine Power.
Under certain conditions, the control module commands the engine OFF.
P2119
DTC P2119 is a Type C DTC.
The control module stores the DTC information into memory when the diagnostic runs and fails.
The MIL will not illuminate.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
The driver information center, if equipped, may display a message.
Conditions for Clearing the MIL/DTC
DTCs P1516, P2101, and P2176 are Type A DTCs.
DTC P2119 is a Type C DTC.
The control module turns OFF the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

Circuit/System Verification
Ignition ON, engine OFF, use a scan tool to observe the throttle position (TP) sensor 1 indicated position. Throttle position should increase as pedal is applied and decrease as pedal is released. When no accelerator pedal activity is detected, The throttle position will return to the spring loaded default position.
Important: A low voltage condition may set this DTC.
Review the Freeze Frame/Failure Records and ensure sufficient ignition voltage was present when the DTC was set.
If voltage was low, verify with the owner that the battery was not discharged. If the battery has not been discharged, refer to Symptoms - Engine Electrical.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
Caution: Turn OFF the ignition before inserting fingers into the throttle bore. Unexpected movement of the throttle blade could cause personal injury.

Inspect the throttle body for the following conditions:
A throttle blade that is NOT in the rest position
A throttle valve that is binding open or closed
A throttle blade that is free to move open or closed WITHOUT spring pressure
If a condition is found, replace the throttle body assembly.
Important: Disconnecting the throttle body harness connector causes additional DTCs to set.
Ignition OFF, disconnect the harness connector at the throttle body.
Ignition ON, verify that a test lamp does not illuminate between motor control 1 circuit terminal B and ground.
If test lamp illuminates, test the motor control circuit for a short to voltage. If the circuit tests normal, replace the ECM.
Ignition ON, verify that a test lamp does not illuminate between motor control 2 circuit terminal A and ground.
If the test lamp illuminates, test the motor control circuit for a short to voltage. If the circuit tests normal, replace the ECM.
Ignition ON, verify that a test lamp does not illuminate between motor control 1 circuit terminal B and B+.
If the test lamp illuminates, test the motor control circuit for a short to ground. If the circuit tests normal, replace the ECM.
Ignition ON, verify that a test lamp does not illuminate between motor control 2 circuit terminal A and B+.
If the test lamp illuminates, test the motor control circuit for a short to ground. If the circuit tests normal, replace the ECM.
Ignition OFF, allow sufficient time for the ECM to completely power down. Connect a DMM between the motor control 1 circuit terminal B and ground.
Important: When measuring peak voltage, ensure that the DMM is on the proper voltage scale and that the response time is set to 1 ms.
Measure for B+ on the motor control 1 circuit terminal B as the ignition is turned ON.
If the peak voltage is not within 1 volt of B+, test the circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
Ignition OFF, allow sufficient time for the ECM to completely power down.
Measure for B+ on the motor control 2 circuit terminal A as the ignition is turned ON.
If the peak voltage is not within 1 volt of B+, test the circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
If all circuits test normal, replace the throttle body.
