  4. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2101 indicated? YES - Go to step 7 . NO - Go to step 5.
  5. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters: Engine speed Vehicle speed Accelerator position
  6. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2101 indicated? YES - Go to step 7. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals the throttle body and the throttle actuator control module, then clean the throttle body (see «THROTTLE BODY TEST»(ref-219376-S21134135652006021400000) ).
