Current data inspection
1.

Monitor current data after engine warming up.

1) "Throttle Position Sensor 1 Voltage" and "Oxygen Sensor Bank1/Sensor1" at idle ("D" range)

2) "Throttle Position Sensor 1 Voltage" and "Oxygen Sensor Bank1/Sensor1" at stall test.

■ Specification

caution

This current data is nothing but an example at certain condition. Thus, the real current data could be different from this example.
