Answer 1

P1176 Bank 1 Oxygen sensor correction after catalytic control linit reached.

This code is a condition that is usually caused by false air,a vacuum leak that occurs after the MAF (mass air flow) such as the mass air flow air tube or ruptured or disconnected vacuum hose.

Comments

The false air can be a leak anywhere beyond the MAF to include your exhaust system. Best to check all vacuum lines and your exhaust before the bank 1 O2 sensor.
