Q: trouble runs fine on 2003 Honda Civic Hybrid

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
P1491 EGR System
P1600 -generic code
p1449, battery deterioration
How can I clean the EGR system, I searched for the PCV valve and could not find it, though I found a fixed entry port into the intake manifold
Are computer updates to the 'brain' & battery free by the dealer?
I'm not entirely positive about the EGR portion of your question, so I will defer to others on that. I can address the last question - on a 2003 Civic Hybrid, there is no remaining coverage at the dealership for updates of the PCM or IMA battery, unfortunately. You can appeal for assistance, but it will likely only be a minimal percentage. Good luck.
