Default Codes P0138 & P0158

Hey community,

I bought a 2006 350z convertible a couple of years back and until now all has been well. It only has 50,000km. I live in Germany.

Anyhow, it recently read code P0300 so I had all of the spark plugs and coil packs replaced. All was then well. 100km later the CEL came back on. This time it was both codes P0138 and P0158. Could the latter be the result of the prior repairs or is it purely coincidental? Additionally, what are the chances that it simply needs new oxygen sensors?

I disconnected the battery and the CEL light is now off. After several kilometers it hasn't come back on.

Hi there did you replaced it with OEM Hitachi Coil packs? Because aftermarket will break very easily!!! Also check your coil packs wires also see if they are connected or if they have broke due to high heat? I used OEM Hitachi and they last a very long time!!!
