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 continuously(Lean). | ▶ Go to "Fuel supply state inspection" procedure. | |
Case2 | HO2S is low continuously(Rich). | Intake air is decreased and MAPS is lowered. | ▶ Go to "PCSV inspection" procedure. |
Exhaust gas is too small. | ▶ Go to "Catalytic converter inspection" procedure. | ||
Excessive exhaust gas | ▶ Go to "Vacuum leakage inspection" procedure. |
