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
This current data is nothing but an example at certain condition. Thus, the real current data could be different from this example.
Symptom | Inspection procedure | |
Case1 | ● HO2S is high continously(Lean). | ● Go to "Fuel supply state inspection" procedure. ● Go to "Injector inspection" procedure. |
Case2 | ● HO2S is low continously(Rich). | ● Go to "Air cleaner inspection" procedure. ● Go to "Vacuum leakage inspection" procedure. ● Go to "Catalytic converter inspection" procedure. |
