QX70 3.0d Cutting out P2293

Hi,

 

I have a QX70 thats started to cut out. Then takes around 7mins before it will restart. Drives perfect until it just stops. Dashboard lights up. 16000 miles just out of warranty.

 

I've read a code of P2293 fuel pressure regulator 2 performance. The local garage thinks it may be water in tank or dirty filter.

 

Has anyone had a similar problem.

 

Many thanks.

Are the battery terminals clean? I had an issue not exactly the same as you but it was found to be dirty connections.

I sold mine. Not sure what Jimbobhill did. What’s the fault code?

Hi Jonny

I don't have an Infinity but looking up the fault code, Google says:

"Code P2293 is a code indicating that the fuel pressure is different than commanded to the injectors by the ECM. The problem may cause various problems due to the fuel pressure being too low or high, if the sensor is failing or failed."

So either fuel pump, fuel pressure regulator, fuel pressure sensor or (less likely as you'd smell it) a fuel leak somewhere.

Sounds like it needs some investigation work...

Dave

EDIT: If I had to guess from the symptoms you've described, I'd say either fuel pump or fuel regulator (just my thoughts so do please treat it as such!)
