Hey guys!

I'm looking for a little help or direction. I have codes P0088 and P0193. High fuel pressure at the rail and I have a new Fuel Rail Pressure Sensor and a Fuel Pressure Regulator on hand so I want to replace them.
I thought the Fuel Pressure Sensor would be a good start at least. Can you guys please help me with the location. I have a 2007 XJR, Is it behind and/or below the Supercharger?

I have been searching on line for hours but cannot pinpoint their locations. Any direction on their locations and how to would be greatly appreciated. Normally I can figure things out on my own but I'm just struggling here.

Thank you for your time!

 

My FRPS is on the end of the fuel rail at the front of the engine.
The one on your engine will be in a similar position and probably
under the supercharger which I do not have.
Yours will have chrome body unlike mine which is black plastic.

 

Meiron1,

Thanks for the reply greatly appreciated. I was thinking it might be there or on the back of the rail and was hoping I don't need to remove the Supercharger.
Perhaps there is a way to lift the SC enough to access it. The end of the Fuel Rail is visible but barely and hopefully the Pressure regulator is nearby too.

Again Thanks for taking the time to reply. hopefully someone with a Supercharger will chime in too. There does not seem to be much of any info out there that I can find.

 

Yes, the sensor/regulator it is at the back end of the rail. See the picture below. The rubber hose runs underneath the supercharger snout.

I am not sure if a good scanner can show you the pressure sensor reading, but I would do more investigation before digging. Removing the supercharger is a big pain and involves a lot of $$$ for “while you are there”

Thank you for posting! Greatly appreciated.

The car drives fine but engine light is on and when I clear the code it comes back on again as soon as you get down the street.

The code on my Rinky Dink Scanner is showing P0088 and P0193. I will take your advice and do more research before commiting to removing the Super Charger.

Thanks again!
