Crank no start, code P1515

Good afternoon,

I attached a description of the code below with a flow chart attached.

The most common cause for this issue is the throttle body.

CIRCUIT DESCRIPTION
The commanded throttle position, based on Accelerator Pedal Position (APP) and possibly other limiting factors, is compared to the actual throttle position. The 2 values should be within a calibrated range of each other. Both the Power-train Control Module (PCM) and the Throttle Actuator Control (TAC) module redundantly monitor the commanded and actual throttle position. This Diagnostic Trouble Code (DTC) sets if the PCM detects an out-of-range condition between commanded and actual pedal position.

CONDITIONS FOR RUNNING THE DTC
DTCs P0601, P0602, P0604, P0606, P1516, P1517, or P1518 are not set.
The following DTCs are not active at the same time: P1120, P1220, P1221
The ignition is in the crank or run position.
The ignition voltage is greater than 8.5 volts.
The TAC system is not in the battery saver mode.

CONDITIONS FOR SETTING THE DTC
The PCM detects that the commanded and actual throttle positions are not within a calibrated range of each other.
All above conditions met for less than 1 second.

ACTION TAKEN WHEN THE DTC SETS
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 and/or the Failure Records.
The control module commands one of the following Reduced Engine Power modes:
- The APP indicated angle is limited to a predetermined value to limit the amount of throttle control.

OR

- The APP indicated angle is limited to 0 percent. The control module only allows the engine to idle.

OR

- Under certain conditions the control module commands the engine OFF.
The message center displays Reduced Engine Power.

CONDITIONS FOR CLEARING THE MIL/DTC
The control module turns OFF the Malfunction Indicator Lamp (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.
Use a scan tool in order to clear the MIL and the DTC.

DIAGNOSTIC AIDS
Inspect for mechanical concerns or binding that may be temperature related. Components may not move freely in extreme heat or cold due to the presence of contaminants or ice formation.
Inspect the TAC module connectors for signs of water intrusion. If water intrusion occurs, multiple DTCs may set without any circuit or component conditions found during diagnostic testing.
When the TAC module detects a condition within the TAC system, more than 1 TAC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing an individual condition may correct more than 1 DTC. Disconnecting components during testing may set additional DTCs. Remember this if you review the stored information in Capture Info.
