10 Oxygen Sensor Ahead of TWC, Bank 1 - Signal Implausible

P0130

10 Oxygen Sensor Ahead of TWC, Bank 1 - Signal Implausible

Diagnosis conditions
- Vehicle at operating temperature, after this 3 minutes idle speed, then approx. 30 seconds increased idle speed.

Possible fault cause
- Short circuit to ground
- Short circuit to B+
- Open circuit
- Oxygen sensor

Affected terminals
- II/2, II/5, II/9, II/15 and II/19

Diagnosis/Troubleshooting

NOTE:
- All electrical faults are recorded under the fault code P0130.
- Do not use contact spray on the connectors to oxygen sensors.

Work Instruction 1 - 12:

NOTE:
- Faults are recorded in these tests. Erase the fault memory.
- Open circuit in wiring in the oxygen sensor cannot be measured. To detect such faults, change between oxygen sensors bank 1 and 2. If the fault follows, then the oxygen sensor is faulty.
- Do not exchange oxygen sensors ahead of catalytic converter and after catalytic converter.
