P1143 code for 2000 Jetta with 2.0 L engine but vehicle has no performance problem?


This code P1143-ecm load calculation cross check upper limit exceeded came on my scanner when the mil light appeared. There is no noticeable change in engine performance but I hate to see the mil light. This happened after my mechanic changed the mass sensor yesterday. How do I fix this?

ATS Advisor:

That code will come whenever the mass sensor that was replaced is not the correct one. Ask your mechanic to get the correct one and have it replaced again.


To prevent ordering the wrong mass sensor, always give the engine code to match the part number of your mass sensor.

Reset the code after replacing the mass sensor.
