P1175

Lambda Control Adaption Fault Bank 2.

P1175 - Lambda control adaption fault bank 2.: Last occurrence - minimum signal

Possible causes:
1. Air leak to inlet bank 2.
2. Air leak to exhaust bank 2.

1. Air leak to inlet bank 2.
- The ECM is unable to maintain the lambda correction.
- Check for air leak paths into the exhaust before the rear O2 sensor.
- Check for air leak paths into the inlet manifold after the air mass flow meter.

2. Air leak to exhaust bank 2.
- The ECM is unable to maintain the lambda correction.
- Check for air leak paths into the exhaust before the rear O2 sensor.
- Check for air leak paths into the inlet manifold after the air mass flow meter.
