O2S Circuit. Slow Response. Sensor 1.







Fault symptom
- Check Engine (OBDII, EOBD).

On-board diagnosis

Type of diagnosis:
- Once per driving cycle.

Enable criteria:
- Battery voltage must be between 11 - 16 V.
- Coolant temperature greater than 70 degree C.
- Motor running more than 180 s.
- Engine speed between 1500 - 3000 rpm.
- Air mass between 200 - 500 mg/C.
- Lambda status 0.
- Lambda integrator between 0 - 15 %.
- Bleeding adaptation more than -10%.

Diagnostics for the following components/systems must NOT have reported a fault:
- Mass air flow sensor
- Crankshaft position sensor
- EVAP Valve
- Shut-off valve, EVAP canister.
- Tank integrity system (EVAP).

Fault criteria:
- When all conditions are fulfilled, the number of combustion is counted during 4 lambda transitions.
- Number of combustions exceeds 160.

Dependent:
- None

System reaction to a fault:
- None

OK report:
- Diagnosis completed without fault report.

Fault handling:
Type III
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
