Random engine light

[LiamTibbs]

Hi everyone,

I wonder if anybody could help me. I have an engine light on my kalos 1.4 which has been on for a while now but have plugged it into a reader and it's saying no codes stored. Has anybody had this issue before or may have any idea on what it might be? I found that the plug to the A/C compressor had rotted so replaced some of the wiring and ploughed it back in. It then came up with fault code P0134 but now fixed that issue and now am back with no faults stored but the check engine light. Any help would be appreciated.

Thanks

Hi, I have finally retrieved a code of p0135 but does anybody know where the wiring for the sensor leads to in the engine bay?
Thanks
