Code P0088 Saturn Description

The fuel injection pump supplies high-pressure fuel to the fuel injection rails, and then to the fuel injectors through high-pressure pipes. The Fuel Rail Pressure (FRP) sensor is a three-wire sensor mounted in the right fuel injection rail. The FRP sensor uses a 5-volt reference circuit, a signal circuit, and a low reference circuit to monitor fuel rail pressure. This information is sent to the Engine Control Module (ECM) to assist in the fueling of the engine. The Diagnostic Trouble Code (DTC) will set when the actual FRP is more than the desired FRP.
