If simulation function of WDS or equivalent is used:

Warm up the engine and idle it.
Connect the WDS or equivalent to DLC-2.
Select the RPM and FUELPW1 PIDs.
Monitor the both PIDs while performing the following steps.
1. Depress the accelerator pedal and increase the RPM PID to 4,000 rpm.
2. Quickly release the accelerator pedal (brake pedal is not depressed) and verify that the FUELPW1 PID is 0 ms. , and 2-5 ms. when the RPM PID drops below 1,200 rpm.
  - If not as specified, inspect the following.
    - ECT sensor and related harness
      (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION .)
    - Neutral switch and related harness
      (See NEUTRAL SWITCH INSPECTION .)
    - Clutch switch and related harness
