Hi I'm Wayne

I will help you with this

give me a few to look it up

HI

The Throttle Actuator Control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well. The TAC system components include, but are not limited to the following: - The accelerator pedal position (APP) sensors - The throttle body - The powertrain control module (PCM) Each of these components interface together to ensure accurate calculations and control of the throttle position (TP). Throttle Body Assembly The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

I hope this helps you

Hi. If this helped you

Please rate my answer 3 or more stars.

That is the only way I get credit for the question

or the money you paid stays at JA and I get nothing for my time.

Diagnostic Step-by-Step
The ignition should always be in the OFF position when connecting or disconnecting electrical components to reduce the likelihood of damage to the components.
 This troubleshooting procedure is based on the assumption that supply power and ground to the PMCI are functioning properly.
 Disconnecting the PMCI connectors during the troubleshooting process will result in multiple errors.
 Specific electrical component information and pin out locations are provided in this procedure as a reference only. Always refer to the technical data sections in Rapido for the most up-to-date changes.
 It is necessary to use DAVIE to clear all current trouble codes from the PCI and EAS-3 ECUs, and then run the Quick Check to identify a change in fault status.
 This DTC can be set as a result of multiple failure modes. For proper fault isolation, complete all troubleshooting steps in the sequence provided.

Check for other faults as this is an informational code as you see that results from another code or problem. Let me know

Customer: replied 2 months ago.
No other fault codes are present and doesn't seem like this is the correct troubleshooting
Expert:  Daniel Wilson replied 2 months ago.

How can it not be correct when I took it out of the MX 13 manual

Expert:  Daniel Wilson replied 2 months ago.

Click this link and check for yourself. I took a screen snapshot

This seems to be just description of the fault my troubleshooting is by Paccar but does not have this code for troubleshooting
Expert:  Daniel Wilson replied 2 months ago.

Click below.... this is the manual I have

Expert:  Daniel Wilson replied 2 months ago.

That is because this fault is initiated by another fault and if you have this code without another fault it points to a software issue. Reflash and update your ECM software to reset it to factory settings.
