SOURCE: Lincoln ls 04 check enging light is coming on and wrench light

You will need a OBD2 code reader, that will give you a "trouble code" then that will tell you what direction to look in, for the problem.

- Engine will not startP0193 DescriptionThe Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signal to the Powertrain Control Module (PCM) corresponding to pressure.


Strain gauge type sensors are consider passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.


Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.


The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder.P0193 Information for specific makesP0193 FORD

I have a 2004 Ford Explorer XLT 4x4 v6 sohc. I have had a service engine light for a couple months. Initially it was giving a P0191 and P0193 code - dealership said replace Fuel pump and filter. So I took...


Check the pressure regulater...Also make sure there is no kinks in the line..You really need to see a data stream instead of just codes..Alot of time people see a code and replace part you need to watch the pressures and see whats going on..Look make sure the vacuum line on the regulator is ok
