Test 1: Check Actual Value G3/1 (O2 Sensor Downstream TWC)
Check actual value G3/1 (O2 sensor downstream TWC)
Test prerequisite
- Engine at idle speed
- At coolant temperature 80�C, start engine and maintain engine speed of 1/min for about 3 minutes.
Status of relevant actual value:
- Temperature of coolant: Communication with ECU required
- O2 sensor voltage downstream of TWC: Communication with ECU required
Specified value
- O2 sensor voltage downstream of TWC: Range must drop below or rise above range 450 to 500 mV 1 times within a minute. (Engine at idle speed)
Question: Are the actual values o.k.?
