Pedal released | Pedal depressed | Sensor Type | |
APS 1 | 700mV~800mV | 3800mV~4400mV | Variable resistance type (Potentiometer) |
APS 2 | 275mV~475mV | 1750mV~2350mV |
APS 1 resistance | 'Supply' terminal ↔ 'Ground' terminal | 0.6 ~ 1.4 kΩ ( 20℃) |
Fig.1) APS 1 signal and APS 2 signal are measured simultaneously, Check if output value is rising and APS 2 signal is 1/2 of APS 1 signal.
☞ APS 2 ground checking signal is for ECM to monitor APS 2. This signal drops APS 2 output voltage to below 200.39mV per 200msec. If APS 2 output voltage does not drop to below 200.39mV, ECM sets DTC as recognizing ground circuit error of APS 2 .
