Some common codes that usually indicate a defective injection pump. Code P1688 always means that the pump is bad, there is no further diagnosis required. Code P0216 is probably the most common code for VP-44 Pumps. If transfer pump pressure has been checked and is good, the injection pump is defective. Other codes that are less common are P0180, P0181, P0215, P0251, P0252, P0253, P0254, P0370, P1287, P1689 and P1690. These codes USUALLY, but not always indicate a defective pump.
