Step 4: Test the reference voltage circuit. Next, using a multimeter, test the 5-volt reference circuit to verify if the voltage is out of specification. If the voltage is indeed off, focus on identifying the problematic component within the circuit, as this will likely be the primary cause of the P0641 code.
