When the engine is at normal temp say after cruising for 20 minutes, does the CTS sensor have any influence on the ECU? I mean when the resistant of it has become below a certain value because the engine is warm enough, does the ECU still uses the value?

The reason I ask because my car is running very lean when the engine is cold or hot. Have tried a numerous of thing, but still haven't found what's the reason.

Rewired the fuel pump, checked the fuel pressure and all is fine.

Hope someone can help me with the question about the CTS.
