Typically when the fuel pressure sensor goes bad, it’ll trigger either P0191 or P0190. If there isn’t enough pressure, you could have an issue with the pump, or something is obstructing the fuel’s journey to the rail.Ī bad fuel pressure sensor should not be accompanied by any symptoms other than the check engine light. If the fuel pressure is ok, you probably have a bad fuel pressure sensor (or the fuel pump has a bad wiring connection). You’ll need to look up the fuel pressure specs for your engine and model year. Here are the most common causes of OBDII P0087.īefore doing anything, check to see if your Ram has a fuel pressure test port at the fuel rail or in the fuel line. It may not even be very noticeable, it just depends on the fuel pressure. Poor Fuel Mileage– Fuel mileage will suffer with low fuel pressure do to the air/fuel mixture being off.The engine will typically run rough or feel choppy when it is misfiring. As long as you fix the lack of fuel pressure, the misfire should take care of itself. If it is misfiring, you’ll likely get P0300 (random misfire, all cylinders) along with the P0087 that brought you here. Misfire– Without enough fuel pressure, your Ram is likely to misfire.It usually feels like it falls flat on its face, or just runs out of go. The most common ones are running at highway speeds and hard acceleration. This happens in situations where you need a lot of fuel pressure. Low Power– If the fuel pressure is too low, it will not allow the vehicle to operate above a certain performance threshold.Here are the most common symptoms of P0087 that you may be experiencing in your Ram.

How bad those issues are going to be depends on whether the fuel pressure is staying consistently low, or if it’s fluctuating in and out of normal operating range. If your Ram is experiencing P0087, it is almost always going to be accompanied by drivability issues. This means that the fuel pump adjusts the pressure going to the fuel rail based on the demands of the vehicle, therefore eliminating the need for a return line.

#Ram pressure codes code
This code is most common on vehicles that use a returnless fuel system. It’s generic, which means that it has the same meaning for the Dodge Ram as it would any other vehicle. This code indicates that there is an issue with getting enough fuel pressure to the fuel rails. P0087 is a relatively common OBD II trouble code.
