                                                      (f)    Use a multimeter to measure the resistance
                                                             between the pin 2, 3 of accelerator pedal or
                                                             lever position sensor 1 connector A026 and
                                                             the ground respectively.

           Is the inspection result normal?
           YES>To step 4.
           No > Maintain or replace the harness.


           4 .    Replace accelerator pedal or lever position sensor
           (a)    Replace accelerator pedal or lever position sensor
           (b)    Use a diagnostic apparatus to perform DTC verification procedures.
           (c)    Implement the steps to read sensor data stream.
           (d)    Check whether DTC exists.
           Is the inspection result normal?

           YES>Replace accelerator pedal or lever position sensor.
           NO >To step 5.

           5 .    Replace ECM

           (a)    Replace ECM.
           (b)    Use a diagnostic apparatus to perform DTC verification procedures.
           (c)    Implement the steps to read sensor data stream.
           (d)    Verify that no DTC exists and the data are normal.
