Question

What is the engine code P2637 for my 2007 Saturn VUE 2.2L?

Answer 1

The P2637 code indicates a communication problem between the Transmission Control Module (TCM) and the Engine Control Module (ECM), or internal problems with the modules. I recommend starting by reprogramming the Transmission Control Module (TCM) and the Engine Control Module (ECM) with the latest software. Here is a link to the code page with more information about the code:
