Order of inspection
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1) Medium
The P0325 code means the computer is not receiving the knock sensor signal, or is receiving it out of range. Without that data it cannot detect engine knock, so it retards the ignition timing as a precaution. The result is a clear loss of power and worse fuel economy, even though the engine runs without any obvious noise.
