P1795

DTC P1795 (3.0L)

Circuit Description
The Engine Control Module (ECM) sends throttle plate position data to the Transmission Control Module (TCM). The data is sent to the TCM through a communication network called the Controller Area Network (CAN). Two circuits are used to communicate CAN data between the ECM and TCM. A fault in the CAN will not cause DTC P1795 to set by itself. If a CAN fault occurs, other DTCs will set before DTC P1795.

When the TCM receives invalid throttle plate position data from the ECM, DTC P1795 sets. DTC P1795 is a type A DTC.

Conditions for Running the DTC
No other CAN errors present.

Conditions for Setting the DTC
The TCM receives no valid throttle plate position data from the ECM for 1 second.

Action Taken When the DTC Sets
^ The TCM requests the ECM to illuminate the Malfunction Indicator Lamp (MIL).
^ The ECM records the operating conditions when the Conditions for Setting the DTC are met. The ECM stores this information as Freeze Frame and Failure Records.
^ The TCM records the operating conditions when the Conditions for Setting the DTC are met. The TCM stores this information as Failure Records.
^ The TCM stores DTC P1795 in TCM history.

Conditions for Clearing the MIL/DTC
^ The ECM turns OFF the MIL after the third consecutive drive trip in which the TCM does not send a MIL illumination request.
^ A scan tool can clear the MIL/DTC.
^ The TCM clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without an emission related diagnostic fault occurring.
^ The TCM cancels the DTC default actions when the ignition is OFF long enough in order to power down the TCM.
