What if replaced my tps sensor but check engine still pops up?

No code ever states what component has failed. A concern with the signal to or from the throttle position sensor does not necessarily indicate the sensor itself has failed. Obviously, based on the fact you have already replaced the sensor, there are further issues that have caused the light to come on, other than the sensor itself. Testing is needed to troubleshoot the code by following a diagnostic process which will check the affected circuit, related wiring and related components for issues.
