Does any one have an ohms figure for a rail pressure sensor on a 1.6 mini direct injection. I'm having trouble with a p0087 which is not hpfp related. ( already replaced) I need to prove the sensors ok before continuing
Good morning,why dont you do a similar test on the rail sensor as the pcm does when the key is turned on using voltage?it is probably a piezo resistive sensor and will be three wire, reference,signal and ground,Most likely a 5v ref ,that is presuming you have good primary pressure to your high pressure pump,
