Hi all, so i got a P0118 CEL light reading 4 weeks ago, and so I replaced the ECT sensor... I'm now getting a P0117 CEL light reading.. What can I do next to further diagnose this issue? It's a new sensor so I'm ruling out that it could be the cause... Could it be the wiring harness, and how hard is this to swap out to the ECU?

 

Anyone? Looks like plenty of views, but no ambition to help? lol
