Hi.
Any ideas
Peugeot 407 2.0 HDI
Fault code p0087 fuel pressure too low
Fault code p0088 fuel pressure too high
Don't know how it can be low and high at same time.
Changed fuel pressure sensor still same fault.
Could it be fuel pressure regulator.
Not got access to pp.
plus codes go off once ignition is turned off.

Thanks for ant help.

HI...what are the problems with your car...those are generic codes and can be misleading
Hi.
When cruising 40mph - 70mph and you put you foot down slight hesitation
Then goes into limp mode. Stop the car engine off read the two fault codes.
Do not delete the codes. start car every thing ok again and fault codes have gone.
