This issue is a thorn in my side:confused:.
P0088 (only code) High Rail Pressure comes and goes, usually after WOT event and then no load or quick stop. worse when its cold out. Lift pump was changed last year.
Research says pressure sensor, pressure regulator, pressure control valve, flow quantity control valve or high pressure pump. I reject the latter as I have no issues with fuel delivery and wot has no issues. I am leaning towards the others. either a sluggish pressure sensor or regulator
What is the consensus as to which is the culprit?
Also research shows that there are options for both parts with MAJOR cost differences.
The pressure sensor (on the rail) from a local dealer is $450.00 canadian. the MB part for same engine is $222.00 US and a BOSCH equivalent is $122.00 US are they truly interchangeable?
Other sensors also available cheaper from other sources than Chrysler/Jeep.
I do not trust my local dealers and I do not know any trustworthy Diesel mechanics in Toronto Canada.
203,000 kms on the vehicle
Any help would be really appreciated
