Code P1925 Description
The P1925 diagnostic trouble code indicates that there is a problem with the fuel additive level circuit being too high. Modern vehicles are equipped with systems that monitor the level of fuel additives in the tank to ensure optimal engine performance and emissions control. When this code is triggered, it means that the engine control module (ECM) has detected a voltage signal from the fuel additive sensor that is higher than the expected range. This could be due to a malfunction in the sensor itself, a wiring issue, or a problem with the ECM.
