has not given up on a nameplate that in its early days inspired astonishing loyalty. Indeed, the Aura is a tangible sign that G.M. The division that got by so long on its customer-hugging New Age spirit now has the Aura, and it's no apparition. But now, in its hour of greatest need, the bosses at General Motors have given Saturn a midsize sedan with the looks, brawn and sticker price to compete with the latest entries from Asia. FOR most of its brief existence as a carmaker, Saturn has been best known as a producer of underpowered compacts whose short list of appealing features barely went beyond their ding-resistant plastic body panels and a haggle-free buying experience. Using a multimeter, check the resistance of the fuel pump by connecting the positive lead to the positive terminal on the pump and the negative lead to the negative terminal.OJAI, Calif. You’ll need to verify what type of fuel system your particular Saturn Aura has. Check the Fuel PumpĪ returnless fuel pump can cause P0088. If the fuel pressure is too high, you’ll need to replace the fuel pressure regulator. If the fuel pressure checks out, you likely have a bad fuel pressure sensor. You’ll need to look up the exact fuel pressure for your vehicle and engine combination. That’s not a tool that most Shadetree mechanics have, you can usually rent one or borrow one from the local parts store.

You’ll need a manual fuel pressure testing gauge. The next course of action when diagnosing P0088 is to test the actual fuel pressure at the fuel rail. Do not connect or disconnect the fuel pressure gauge with the engine on.

Make sure you have a fire extinguisher ready in case the fuel sprays.

It’s always best to do it with the engine cold. Check the Fuel Pressureīe careful when checking your Aura’s fuel pressure. If there are, you’ll need to repair or replace the harness. Make sure that the harness is plugged into the sensor tightly and that there are no damaged pins inside the connector. It’s not uncommon for a rodent to nest around the intake, particularly in the wintertime. Due to its location, damage to the harness is very common. Make sure that it is not burnt, cracked, or frayed. Take a look at the fuel pressure sensor wiring. Start here (particularly if your Aura is running fine).

While several things can cause the P0088 code in the Saturn Aura, here’s a good order to diagnose them in: Inspect the Fuel Pressure Sensor Wiring

Wiring issues at the fuel pressure sensor.

Here are the most common causes of P0088 in the Saturn Aura:

Misfiring (you’ll likely see code P0300, focus on P0088 first).

Here are the common symptoms associated with P0088 in the Saturn Aura: There may not be any symptoms if the fuel pressure sensor is bad. There will almost ALWAYS be symptoms associated with P0088 if the fuel pressure is incorrect. If it’s not working correctly, the engine may stall or run rough. The fuel pressure sensor signals the pressure in the fuel rail to the PCM. The fuel pump can adjust to the needs of the engine directly, with no regulator needed.

The other way is that the fuel pressure is regulated by the fuel pressure sensor, as it works with the PCM.

The first way is to use a fuel pressure regulator, which returns the extra pressure to the fuel tank.

There are two ways that an engine can have its fuel pressure regulated. Knowing how your car’s fuel pressure is regulated can help you figure out the faulty component. The main components that can fail and cause P0088 are the fuel pump, fuel pressure regulator, and fuel pressure sensor. If any of them are faulty, it could cause a code P0088. Several components make up the fuel system. If the fuel pressure is too high (the voltage value coming from the fuel pressure sensor is over the maximum value), it signals your Aura’s PCM to display code P0088. Too much fuel can lead to just as many problems as no fuel. The purpose of the pressure monitoring system is to help the engine run by monitoring the fuel pressure from the fuel injection system. This code is set when your Aura’s PCM detects too much pressure in the fuel system. P0088 is a generic powertrain code that indicates a fuel pressure issue. P0088 Definition: Fuel Rail/System Pressure – Too High While P0088 is a generic code, repair steps will vary depending on your Aura’s model year, engine type, and how it regulates fuel pressure. In layman’s terms, it indicates that your car’s fuel pressure is too high. P0088 is a common OBD2 trouble code that can occur in the Saturn Aura.
