Pressure sensors for fuel/air/oil
Hi all,
Im using a few of these cheapie from ebay: http://www.ebay.com/itm/Pressure-transd ... 0785454553
Im using 3, for oil pressure, fuel pressure and coolant pressure.
Looking at the reading ive been getting, they dont seem to be reliable.
Is anyone else having problems with these sensors?
Any suggestions for better quality sensors that arent $100+ ea?
Thanks!!

Re: Pressure sensors for fuel/air/oil
Same concept, slightly more expensive, will probably have been through quality control: http://www.aemelectronics.com/products/ ... ig-sensors
I will gladly pay twice and three times the price to avoid the chinese knockoffs, they only seem to be trouble no matter what they are - ignition modules, coils, sensors, you name it.

Re: Pressure sensors for fuel/air/oil
The transducer you linked to are 30psi. Actual pressure is exceeding the Transducer limit.MWPau wrote:Hi all,

Scroll to the bottom of the page there is calibrating info and other pressure ranges.
This link is for a 100 psi might work better for oil and fuel pressure.

Scroll to bottom of page there are other pressure ranges available.
Along with calibration information.
Re: Pressure sensors for fuel/air/oil
Im not that stupid ;)
Im using a 30psi for coolant pressure, fuel & oil are identical but 100psi.
Are they vibration sensitive?
Both the oil & fuel pressure sensors are mounted on the head.

Re: Pressure sensors for fuel/air/oil
Did you calibrate them in Tuner Studio?
Re: Pressure sensors for fuel/air/oil
Yup.
They seem to get "stuck" at a value much less than the real value now and then.
For example, oil press sensor will read ~22psi for a few mins, before moving to the correct 55psi.
I do have a old school oil-filled gauge im comparing the values with.

Re: Pressure sensors for fuel/air/oil
Good to know these parts are not reliable. I purchased two of them myself.
Here is a oil pressure sensor on E-bay, appears to be a GM part. Don't know how high it reads, but might be able to use for fuel and coolant pressure.

Still looking for a fuel pressure sensor.

Re: Pressure sensors for fuel/air/oil
I asked the eBay seller about the problem, and the new stainless version they are selling.
http://www.ebay.com/itm/261260635816
He said "the $24 version stainless steel is much reliable then brass version before.".
Who knows if they actually are, or if he just wants to sell more...
That GM sensor looks interesting.
http://www.yellowbullet.com/forum/showt ... p=23492634
Im guessing that if its oil safe, it would be ok with fuels too?

Re: Pressure sensors for fuel/air/oil
I have a couple of the stainless version, but haven't put them on the car as yet.
If you want I could pressure cycle them attached to an air line for a bit, but I don't have the fittings on the engine for them to go into just yet.

Re: Pressure sensors for fuel/air/oil
Doing an E-bay search for fuel pressure sensor, turned up Diesel fuel pressure sensors, would they work.
Also turned up this generic fuel pressure sensor.
http://www.ebay.com/itm/Pressure-transd ... 43&vxp=mtr
I have the stainless steel version also. Didn't notice the difference earlier.
Hay_Allen would be interested in test results you find, if you test them.

Re: Pressure sensors for fuel/air/oil
Perhaps try one of the Honeywell PX2 sensors.
e.g.
http://www.digikey.com/product-detail/e ... ND/2839650
I use a couple of older(?) MLH models on my car - one is 100psi for fuel, the other is 2000psi for nitrous - but they are nearly double the price.

Re: Pressure sensors for fuel/air/oil
The GM part look like a simple pressure switch. The simply close or open at some set pressure => useless.

Did you read the topic that was linked where a user has tested it and plotted the pressure:voltage response??subwoofer wrote:The GM part look like a simple pressure switch. The simply close or open at some set pressure => useless.

Re: Pressure sensors for fuel/air/oil
I would like to know if did gm sensor could be used for fuel too.
Re: Pressure sensors for fuel/air/oil
You can see here what the brass oil pressure sensor is reporting
I'll buy the GM version to replace it, and report back.

Re: Pressure sensors for fuel/air/oil
Ive used both the brass and now the stainless version of the pressure sensors from EBay. They seem to work ok for me. The paperwork that came with mine said it should be within 2%. I'd like to add a temp sensor for fuel, (I have 2 Schedar valves in my fuel rail) but I only have 1 analog in left. Its the hard to get to one so that won't be happening anytime soon.

Re: Pressure sensors for fuel/air/oil
I've had the brass one fail where it read way off of what it should read. Also, the internal seals are absolute garbage. I have oil showing up in the connector all the time.
