(b)Turn the ignition switch ON.
(c)Check that the voltage (ACCEL POS) of the CURRENT DATA shown the standard value. Accelerator pedal released: 0.5 to 1.1 V
Accelerator pedal depress: 2.6 to 4.5 V
(d)Check that the voltage (ACCEL POS #2) of the CURRENT DATA shown the standard value.
Accelerator pedal released: 1.2 to 2.0 V
Accelerator pedal depress: 3.4 to 5.3 V
If you have no hand±held tester, measure voltage between terminals (VPA1 ± EP1, VPA2 ± EP2) of the ECM
