Check engine light appeared on my 08 Grande Punto.

I was diagnosed a PO135 error code. I replaced the lambda sensor this morning, started it up and, to my disappointment, the light remains.

Any ideas?


Thank you

If you've not reset it with a scan tool, then you may find it can take up to 30 miles to extinguish.
Take it for a run, or find a scan tool.

Tidy. Thanks for the information.
