Step 1: Diagnose the Problem

Before you can fix the B1290 error code, you need to figure out what’s causing it. The first step is to use an OBD-II scanner to read the code and determine the specific problem. In this case, the code indicates that there’s a short circuit in the servo motor potentiometer air intake right circuit.
