When the Ford fuel push sensor stops working some of the usual symptoms incorporate an engine that is hard starting or one through a severe absence of power. Return these space the main symptoms of the condition, fail of the fuel rail sensor will virtually always set a diagnostic trouble code.

The most famous codes collection by a defective original equipment component remain the P0190 and the P0193. These was standing for fuel rail press sensor circuit break down and system circuit high output detected. In both situations the break down of the push sensor pressures the computer to start guessing in ~ the ideal 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 whole fuel return system. Currently they usage this push sensor come send the computer system real-time data therefore it can use this info to manage the fuel pump procedure on the fly.
We contact the turning on and also off that the fuel pump to accomplish the correct push pulse broad modulation. This system worked pretty fine up till this point. However, as these cars and also trucks equipped with this form of system strategy 10 years 100,000 mile we"re starting to view 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 previous $100. Hence we have to verify that this component stays the true root reason of all of our problems. Here we"ll talk about how to make a couple of tests at the four wire connector prior to condemning the part.If you decide you desire to change the Ford fuel press sensor on her own, I have a couple of tips listed below to assist the project go a small smoother. Although the fuel rail sensor mounts in a practically location, it"s an installed in the fuel rail it is holding back 65 psi of fuel pressure. Therefore, you need to make certain you depressurize the system before you eliminate the retaining screws. Watch the procedure below in the technical tips section.Finally, we"ll cover a couple of common questions about the instead of parts. It"s tempting to shot one the those $14 made in China sensors. However, unless you have a the majority of time and also patience ns don"t recommend this route. See great compromise between a brand-new dealership branded part and the cheapest the the aftermarket choices in the components section.
Diagnosing Injector press Sensors
In the Ford business manual they call this part an injector press sensor. However, the rest of the civilization is calling this the Ford fuel press sensor. This becomes important when you effort to uncover replacement parts.
I"m a large believer in testing automotive electric components before replacing them. Return the Ford fuel press sensor remains a weak spot v a high failure rate, other an easy problems can reason the same P0193 diagnostic problem code.
When friend look at the sensor you"ll see a red vacuum line connected to one side of the part. ~ above the backside you"ll check out a four wire plug the we have the right to perform some rapid diagnosis on.
With the an essential on and the engine turn off we deserve to either back probe or disconnect the connector and also check for the 5V referral signal native the cars key computer. Top top the 2005 version year, you"ll discover the 5V referral signal at terminal 2. Identify the referral voltage wire by color.
They provided a brown wire with a white tracer. This seems to apply throughout all the the famous models like the Ford Focus, the Taurus, Escape and Explorer sport-utility vehicles. V that said, various other years and other models might possibly usage a different shade wire. If you have actually the 5V reference signal at terminal 2 and also you have a strong manifold vacuum signal at idle native the red vacuum line attaching to the pressure sensor, you probably have actually a bad part.Although I have actually come throughout the check engine light code P0193 on a couple of different Ford vehicles, so far, the only thing I"ve uncovered is a defective sensor. Another interesting point to make is this part seems trustworthy until it gets close come 100,000 miles. Keep in mental this can be a simultaneous on the vehicles the I"ve seen. Walk forward, I will probably just go ahead and also replace the component on vehicles that collection the code and also show much more than 100,000 mile on the odometer. I’ll article an update here if I get burned and find an additional root cause.
Choosing Ford Fuel Sensor Parts
There"s no question that we"re starting to see an elevated failure price of the Ford fuel press sensor on high mileage units. As the trend continues prices will certainly come down. And also we are currently seeing this.When you have actually an old drive it"s only natural to shot to spend much less money ~ above parts. However, my an individual experience is no favorable with the ultra low priced replacement fuel injector sensors I"ve tried. After having actually a couple of experiences with poor parts appropriate out of the box, I began to use the Motorcraft parts over the aftermarket ones. Unfortunately, the little plastic sensor comes through a steep price tag as soon as purchased with my regional dealership.
Most plastic computer input sensors lug a price tags in the $50 range. V that said, this is a dual sensor that senses both fuel temperature and also pressure at the same time. Nevertheless, the Ford dealership quoted a price simply shy that $150 for parts.In an effort to to win a compromise between the low quality replacements uncovered on the Internet and the super expensive one found at the dealership, ns tried the Bosch instead of part. Back in mine day this firm had a great name. Unfortunately, i hear they room not the same company they usage to be. V that said, so much I"ve had great luck. At less than fifty percent the price that the dealership providing this has worked out for me for this reason far. If I carry out experience troubles with the Bosch, Ford fuel pressure sensor I will certainly come back here and amend this an individual observation.
Replacing the Ford Fuel press Sensor
On an initial glances the Ford fuel pressure sensor looks like a to walk in the park come replace. And also it is, but we have actually one major concern come consider before we start removing the little bolts. This part measures fuel pressures better than 60 psi.In a nutshell, if you remove this ingredient on a totally pressurized fuel rail, gas is going to spray everywhere the engine compartment. Imagine how bad this would certainly be if the engine is at complete operational temperature. Nevertheless, this potential for damage way that vigilance is required.Before you eliminate the assembly you have to make sure to depressurize the rail. Letting the vehicle sit overnight becomes the easiest method to manage the situation. If you change the component on a cold engine that hasn"t run in the last 24 hours, over 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 situation we’ll have to run the automobile and then disconnect the fuel pump till the engine stalls. There is another possibility on some models and also engine sizes.On part models Ford set up test ports near the input manifold so that technicians can take fuel press readings for diagnostic purposes. Friend can connect a fuel push test gauge come the Schrader valve fitting and also use the bleed switch on the tester to safely remove all fuel press in the system.Always use hand tools about fuel system repairs, since electric and battery-operated tools make sparks that can ignite fuel vapor. Also when you remove all fuel press from the rail you have to still ingredient a few rags under the rail to absorb any type of fuel leakage during the instead of procedure. Likewise be careful with the vacuum line once you traction it off of the port. These vacuum lines room getting an extremely brittle on 10 year old cars through 100,000 miles.I installed a Ford fuel pressure sensor on my friends Ford Focus. If girlfriend own among these rides you can want to learn how a brand-new engine mount fixes idle vibration ~ above the Ford four-cylinder cars.
