Hi all, I have a prpblema on this car lost power and turns on the failure... In the diagnosis by this code. DF503 function of pressure tuning fork(pressure too low) . Engine code f9q... by chance do you know what, and the sensor in question, or what to do ? Thank you in advance
pressure tuning fork???
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
? the explanation that from the diagnosis
attaches to the scanner, and I see a p? the press rail as st?....
usually the minimum should be around you 300 bar....
if so, doesn't it ? test first to see if your sensor rail ? ok....
without necessarily change it..but let us two tests..
if the sensor should be good, but the poor press checks that the circuit of the low-pressure fuel is ok...
the first thing you need to check that the pressure relief valve integrated in the filter is off, and it gives you a lot of pressure in the circuit..usually the press of the circuit of the low-pressure needs to be around you and 2-2,5 bar non the less..

low pressure not less than 3 bar, high pressure, to a minimum of 280 to 350 bar
for the rail pressure just went to see the rail goal..
for the low-pressure s I for sure that the press st? has 2-2,5 bar....
but if you say that must be not less than 3 bar, it means that you have info found that they say so....
or no??

freddyecu sorry but you can't find a code eobd standard, pressure adjustment the fork ? a p? incoprensibile difficult to help you..***** s, I would look at prex diesel but also that turbo...to diagnosis see the output in volts of the sensors if ce n'? one who shoots...
however, the fault DF053 that corresponds to the dtc 0089 means problem rail pressure too high, too low, or problem in the adjustment I verificherei the pressure regulator on the pump, rails very often breaks the seal and does not correctly adjust the ecu is aware of this because it opens the DRV too much to keep up the pressure to that objective....as to the minimum pressure ever under 3 bar is usually between 3 and 3.8 4 the engine while the high pressure bike varies from 280 to 350 depending on the temperature, pressure, etc.
for the minimum pressure, I agree with you that it should be above 3 bar, but I invite you to take 10 machines that work regularly and measured the pressure minimum, 10 maximum 5 exceeds 3 bar, the others are all below.
certainly I have not said that it is not positive to have the 2.8, but the best would be above 3 bar, it all depends on the state of wear of the pump low-prex and when and dirt in the fuel filter, etc., in line of up to 3 bar, more or less, you can accept...we see our friend what we will know
