Monitor Description

Function Explanation (DTC Detection Outline) (200 Pin Type) 

• If the voltage between ECM terminal C27-81 and ECM terminal C27-82 exceeds the specified range with the A/F sensor activated, the element in the A/F sensor could deteriorate. To prevent this, the ECM stops control of the A/F sensor and stores a DTC.

Function Explanation (DTC Detection Outline) (186 Pin Type) 

• If the voltage between ECM terminal C28-4 and ECM terminal C28-3 exceeds the specified range with the A/F sensor activated, the element in the A/F sensor could deteriorate. To prevent this, the ECM stops control of the A/F sensor and stores a DTC.
