Pinpoint Tests QE: Electronic Throttle Control (ETC) System: Introduction
NOTE:
Soldering is the only approved circuit repair method for the electronic throttle body (ETB) circuits, the throttle position (TP) sensor circuits, and the accelerator pedal position (APP) sensor circuits. Refer to the
Connector Repair Procedures article the recommended solder splicing procedures.
This pinpoint test is intended to diagnose the informational PCM DTCs.
The informational DTCs are the result of the failure mode effects management (FMEM) operating strategy that maintains limited vehicle function in the event of a PCM, harness or component concern.
Circuit DTCs can be accompanied by the informational DTCs and should be diagnosed first. Informational DTCs without circuit DTCs may or may not indicate the actual concern and should be diagnosed as a symptom.
