P2290=Injector pressure too low.
With a P2290, the fault sets when actual pressure is less than the commanded by a specified value. Greater than 1 MPa (4-5 ICP commanded), greater than 3 MPa error (6-27 MPa ICP commanded).
Just in case you were wondering, MPa is a metric (SI) unit for pressure, or force per unit area. Pa is the Pascal, which is one Newton of force applied to one square meter of area (1 N/m2). MPa is a mega-Pascal, or one million Pascals. Since atmospheric pressure is 101 000 pA, or 101 kPa(approximately 14.7 psi), this is approximately 9 atmospheres (around 150 psi).
So, I'm guessing your ICP is bad?
Hope that helps you some.
