fuel rail pressure sensor.

[timelessconstructionllc]

My truck is throwing code p0191. From What I understand That means I need to replace the fuel rail pressure sensor. Damn things expensive. Can anybody tell me What my options are?

We have Good Use ones $50. 00 1 Year warranty... otherwise Genos has them New $129. 00

Best buy is the whole fuel rail asy from GENO's Pressure sensor and blow off valve.

The rail manifold, valve and sensor costs $305 from genos. Is the manifold something that normally has to be replaced at some point? Anyone have any experience with the used sensors? How hard is it to change our the sensor versus the whole manifold.

No, Geno's just found it was cheaper to buy all those parts together rather than just the valve alone.
Me? I'd buy one of TC's sensors.

TCDiesel- what kind of life do people typically get out of your used sensors?



Prariedog- thank you.

I have never had one fail... . Yet... Had to replace one that the customer broke,socket slip off and broke the plastic body.

does it turn on the check engine light when it goes bad or do you just have to check to see if theres a code stored

Not always..... to both.

My check engine light came on

Find a buddy with a known good one before buying one. Try it on yours, if it cures the problem, then replace it. With the CR system, it could be anything, and you dont want to waste that hard earned cash throwing parts at it.

My check engine light mysteriously went off today. Anyone have ant idea why or what that means?

 

[Prairie Dog]

That means what ever it was, cleared itself up (for now?) and then things went back to normal. If the problem goes away, the CEL will turn itself off after 9 restarts. You may never see it again.

Through recent experience, if your sensor is bad it will throw a code and the motor will most likely rattle a bit. (my sensor wasnt bad... just a lot of fuel system problems lately) Did it make an odd noise? The sensor reads the rail pressure returning data to the ECM which in turn uses that (among other things) to control the FCA. If the RP sensor is not sending a signal, the ECM will command full pressure and the FCA will give it, thus producing some injector rattle.



Keep an eye and ear out for this, it is NOT good to drive your truck if this is occuring... leads to sure death of your injectors $$$!!!

I've just recently been through a similar experience and now appear to have it fixed. Mine was throwing codes P0193 (fuel rail pressure sensor voltage high) and P0236 (Turbo Boost Sensor A-Circuit Range / Performance). It started doing it about every 60-75 miles the first day, and each episode was was accompanied with a very brief rough idle and audible engine knock. I immediately shut it down each time, and it would immediately restart without similar issues. I had never had this happen before, but do have 255,000 miles on the truck with original injectors. I tried to self-diagnose the problem, and ended up disconnecting my Edge E-Z (as I see you have one) to see if it played a role. Engine ran extremely smooth, and never missed a beat or threw another code over the next 1200 miles. I called Edge Products, explained the symptoms and codes thrown. Their tech fellow was very helpful and acknowledged that those codes could indeed be related to the EZ module and it may have had an internal failure. As my EZ unit had been on my truck for over 8 years / 255, 000 miles, I sent it in to them and obtained a new replacement for a greatly reduced price. I re-installed it this past week and have had no further problems with codes or performance in several hundred miles of driving. At this point, I feel the whole issue was related to my Edge EZ.



I would suggest trying yours without the EZ connected and see if you get more code activations. If you do, then as others have suggested, try changing out your rail pressure sensor and go from there.



Hope this info is of some help to you, and good luck with it!
