(f) Use a multimeter to measure the resistance
between the pin 2, 3, 4, 5 of accelerator pedal
or lever position sensor connector A026 and
the ground respectively.
Standard resistance
04 Multimeter connection
Standard value
pin
A026（2）- ground ＞ 10MΩ
A026（3）- ground ＞ 10MΩ
A026（4）- ground ＞ 10MΩ
A026（5）- ground ＞ 10MΩ
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.
