Diagnostic Mode 5: Check Output of Oxygen Sensor Signals
Diagnostic Mode 5: Check Output Of Oxygen Sensor Signals
Function
The static values of the oxygen sensors are indicated via this diagnostic mode.
The values of the individual oxygen sensor test results must reach the specified value or must be within the min.- and max.- limits.
Requirements
- There must not be any DTCs stored in DTC memory, Diagnostic mode 3: Check DTC memory. Diagnostic Mode 3: Check DTC Memory
- Coolant temperature must be at least 80 degree C, Diagnostic mode 1: Check measuring values; PID 5, Coolant temperature. Diagnostic Mode 1: Check Measured Values
Procedure
- Connect diagnostic tester. Diagnostic Tester, Connecting
