When the Ford fuel push sensor falls short some that the common symptoms include an engine the is hard starting or one through a severe lack of power. Although these room the major symptoms that the condition, fail of the fuel rail sensor will nearly always set a diagnostic problem code.

The most popular codes collection by a defective original equipment part remain the P0190 and also the P0193. These stand for fuel rail pressure sensor circuit breakdown and mechanism circuit high calculation detected. In both cases the breakdown of the press sensor forces the computer system to start guessing in ~ the finest fuel mixture.The exciting thing about a Ford fuel press sensor is this relatively brand-new design eliminates the old-style fuel push regulator and also elimination of the entire fuel return system. Currently they usage this pressure sensor come send the computer system real-time data for this reason it can use this details to regulate the fuel pump procedure on the fly.
We call the turning on and off the the fuel pump to achieve the correct pressure pulse width modulation. This system operated pretty fine up until this point. However, together these cars and also trucks equipped through this type of system strategy 10 years 100,000 mile we"re beginning to check out an elevated failure rate of the component the reports pressure earlier to the computer.
Unfortunately, the price of this plastic part, brand-new indigenous the dealership pushes well past $100. Therefore we have to verify the this component stays the true root reason of every one of our problems. Right here we"ll talk about how to make a few tests in ~ the 4 wire connector prior to condemning the part.If you decide you want to replace the Ford fuel press sensor on her own, I have a few tips below to assist the task go a little smoother. Back the fuel rail sensor mounts in a practically location, it"s placed in the fuel rail it is holding earlier 65 psi of fuel pressure. Therefore, you have to make sure you depressurize the system prior to you eliminate the retaining screws. See the procedure below in the technological tips section.Finally, we"ll cover a couple of common questions around the replacement parts. It"s tempting to shot one of those $14 make in China sensors. However, unless you have a many time and patience ns don"t introduce this route. See wonderful compromise between a brand-new dealership branded part and the cheapest the the aftermarket choices in the components section.
Diagnosing Injector push Sensors
In the Ford service manual they call this part an injector push sensor. However, the remainder of the human being is phone call this the Ford fuel press sensor. This becomes crucial when you effort to discover replacement parts.
I"m a large believer in testing automotive electric components prior to replacing them. Back the Ford fuel push sensor remains a weak spot v a high failure rate, other straightforward problems can cause the same P0193 diagnostic trouble code.
When friend look in ~ the sensor you"ll view a red vacuum line connected to one next of the part. On the backside you"ll watch a four wire plug the we can perform some fast diagnosis on.
With the an essential on and the engine off we can either back probe or disconnect the connector and also check for the 5V recommendation signal indigenous the cars key computer. Top top the 2005 version year, you"ll uncover the 5V referral signal at terminal 2. Determine the reference voltage wire by color.
They provided a brown wire v a white tracer. This seems to apply across all the the renowned models choose the Ford Focus, the Taurus, Escape and Explorer sport-utility vehicles. Through that said, other years and other models can possibly usage a different shade wire. If you have actually the 5V reference signal in ~ terminal 2 and you have a solid manifold vacuum signal at idle from the red vacuum heat attaching come the push sensor, girlfriend probably have a negative part.Although I have come throughout the inspect engine light password P0193 top top a few different Ford vehicles, so far, the only thing I"ve found is a defective sensor. Another interesting point to do is this part seems reliable until it it s okay close to 100,000 miles. Save in mental this can be a coincidence on the vehicles the I"ve seen. Walk forward, I will probably just go ahead and also replace the ingredient on vehicles that collection the code and show more than 100,000 miles on the odometer. I’ll short article an update below if I get burned and also find an additional root cause.
Choosing Ford Fuel Sensor Parts
There"s no inquiry that we"re beginning to see an elevated failure price of the Ford fuel pressure sensor ~ above high usage units. Together the trend proceeds prices will come down. And we are currently seeing this.When you have actually an old journey it"s only herbal to try to spend less money on parts. However, my personal experience is not favorable with the ultra low priced replacement fuel injector sensors I"ve tried. After having actually a couple of experiences with negative parts appropriate out the the box, I started to use the Motorcraft parts over the aftermarket ones. Unfortunately, the small plastic sensor comes through a steep price tag once purchased v my regional dealership.
Most plastic computer system input sensors bring a price tag in the $50 range. With that said, this is a twin sensor that senses both fuel temperature and also pressure at the very same time. Nevertheless, the Ford dealership quoted a price simply shy the $150 because that parts.In an effort to to win a compromise in between the low high quality replacements discovered on the Internet and the at sight expensive one found at the dealership, ns tried the Bosch replacement part. Earlier in mine day this agency had a great name. Unfortunately, ns hear they space not the same firm they use to be. V that said, so far I"ve had an excellent luck. At much less than half the price that the dealership giving this has settled for me so far. If I carry out experience difficulties with the Bosch, Ford fuel push sensor I will come earlier here and also amend this an individual observation.
Replacing the Ford Fuel press Sensor
On first glances the Ford fuel pressure sensor looks like a walk in the park to replace. And also it is, however we have actually one major concern come consider before we begin removing the little bolts. This component measures fuel pressures higher than 60 psi.In a nutshell, if you remove this ingredient on a fully pressurized fuel rail, gas is going come spray all over the engine compartment. Imagine how bad this would be if the engine is at full operational temperature. Nevertheless, this potential for damage means that vigilance is required.Before you eliminate the assembly you need to make sure to depressurize the rail. Letting the car sit overnight becomes the easiest method to take care of the situation. If you replace the component on a cold engine that hasn"t run in the critical 24 hours, there won"t be any kind of fuel press in the rail.

Unfortunately, we don"t constantly have that high-end of waiting for the press to dissipate in the rail. In this case we’ll need to run the automobile and then disconnect the fuel pump till the engine stalls. There is another possibility on some models and engine sizes.On part models Ford installed test ports near the intake manifold so that technicians have the right to take fuel pressure readings for diagnostic purposes. Girlfriend can affix a fuel pressure test gauge come the Schrader valve fitting and use the bleed button on the tester come safely eliminate all fuel press in the system.Always use hand tools approximately fuel device repairs, since electric and battery-operated devices make sparks that might ignite fuel vapor. Even when you remove all fuel push from the rail you have to still ingredient a few rags under the rail to absorb any kind of fuel leakage throughout the replacement procedure. Also be careful with the vacuum line once you traction it off of the port. These vacuum lines are getting really brittle ~ above 10 year old cars v 100,000 miles.I installed a Ford fuel push sensor on my friends Ford Focus.
