I had my engine mount replace and have the engine clean to find a leak, replace the gasket on the oil filter mount where the leak is coming from. Car works fine except the CEL comes on and shows a code P105. I don't have an idea where the MAP sensor is or is it Knock sensor ? I'm lost with all this sensor. Is there someone who knows where it is and how it looks like? picture is a big help and thanks in advance......

 

Thats a circut malfunction.

A vacuum line leading to or from the intake maniforld probably got knocked loose when the engine was cleaned.

Look at the areas where cleaning was morre concentrated.

 

Thanks, I was just there in walnut creek last week and hope the smoke are gone by now
