I'm getting intermittent engine light coming on in our WG 2.7 Jeep.
It still runs fine and is showing P 0190 code which I understand is "high pressure fuel rail sensor" problem.
The engine light resets when the motor is switched off and may not appear for another few days. As mentioned it starts and runs normally.
I'm wondering if a partially blocked fuel filter could be the cause as it hasn't been changed for quite some time.
Has anyone had this problem and could throw some light on my issue. I'm reluctant to change the filter if not necessary as I believe they can be a bit difficult to bleed all of the air out of the system
Thanks
Graeme
