Question

Just got these two codes on my 2005 Nissan Quest:
P1051 & P1168.
Would this still be covered under warranty?
What exactly do the errors mean?
Thanks!!!

Hi there,

Both codes are related to the bank 1 heated O2 sensor. This is the first sensor on the exhaust manifold on the bank closest to the firewall. In most cases replacing the sensor resolves the issue.
