P1259 - VTEC System Malfunction
P0325 - Knock sensor malfunction
P1166 - 02 sensor sensor 1 malfunction
P1167 - 02 sensor sensor 2 malfunction
P1456 - evap leak - Most common leak is gas cap
P0845 - Transmission Fluid Pressure Sensor/Switch 'B' Circuit

i would have these fixed as soon as possible or you could damage other components, those issues are vital to having the car running properly.

The 02 sensors and the knock sensor are fairly easy depending on where they are located, you will need some tools to tackle those jobs. As far as the transmission, vtec and evap leak those require some knowledge in diagnosis and may require specialty tools to find the issue. I have 15 years experience in the automotive industry and also ase certified.

 

 

I would purchase a factory gas cap from honda, easy way to check is pull the cap off and inspect the seal on it.

Sounds like you def need to replace the 02 sensor, if it came up immediately after clearing them i would also check the connectors and wiring going to those sensors. Most times it will take the car a couple of key cycles before the codes come back up. it needs to see the issue a couple times before it throws the code again. you want to check pending codes in the scanner if yours has that option, that will let you know what other codes the computer has stored.
