Circuit Description
The throttle position signal is used by the ASM to control the actual throttle position that is requested by the EBCM. The EBCM compares the Delivered throttle position sensor value that is sent from the ASM to the throttle position sensor value sent from the PCM over the Class 2 serial data line.
Conditions for Setting the DTC
DTC C0182 will set if the ASM delivers current greater than 18 amps to the Accelerator Control and Adjuster for more than three seconds without the cable adjuster reaching its desired position.
Action Taken When the DTC Sets
| • | A malfunction DTC is stored. |
| • | The TCS is disabled. |
Conditions for Clearing the DTC
| • | Condition for DTC is no longer present and scan tool clear DTC function is used. |
| • | 100 ignition cycles have passed with no DTCs detected. |
Diagnostic Aids
If an intermittent malfunction exists refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
