P1117 - can't clear code

You said the Air pump works so I am going to assume you triggered it with your Durametic to check it.

So you need to make sure the air pump kicks on when you first start the car from a cold start. Confirm that it kicks on from cold start before going further.

This is why.
One of the things the DME/ECU looks at on cold start is coolant temp.
If the coolant sensor shows close to ambient temp. (cold engine). it triggers the SAI air pump.
If by chance your coolant temp sensor does not show close to ambient temp. at cold start.
Then the DME/ECU is going to react as if the engine is already warm so it will not trigger the Air pump. Thus possibly triggering a SAI code.

So a faulty coolant temp sensor that still operates but not properly can trigger other codes without triggering a fault code for a faulty coolant sensor.

Damn
I hope that makes sense
