OK these got mixed up in my tool box and I was thinking that the copper looking sensor is the 5 BAR. Can anyone help me on this?????

PLEASE!

 

look up the part number

the silver sensors are the newer ones, they dont use the brass ones anymore

 

copper is 3.5 bar and silver is 5 bar

 

how can you tell.. i cant see the part numbers on those things.

they switched ALL their pressure sensors over to teh silver ones.

 

the brass one is:

35-2109

trhe silver one is:

s/n 050422073

 

the 35-2109 is a 5bar

the sn is not the part number, but if you know you had a 5 bar and a 3.5 bar then i guess its a 3.5 bar.

the wiring for the 2 is the same, so when you wire it up and set the wizard make sure to check the load w/the engine off, if its not close to 0psi then you have the wrong one.

 

This is the other number on the silver sensor:

p51-50a-b-p18-4.5v

thats the only other numbers on there.

****ALSO...

does anyone know what sensor AEM uses with the wide-band gauges?? I heard it was a VW sensor and I was wondering if anyone knew what year VW it came from.

I just got a 5 bar map and part # 30-2130-75

 

the part number for ALL the new sensors should be 30-2130-XX

the old sensors had the completly different part numbers.

 

I am looking at my AEM 3.5 bar map sensor right now, and it is identical to the sensor on the left. I also have the part # that is on the box for the 3.5 bar map sensor which is: 30-2130-50.


edit: here is the number that is on the sensor: P51-50A-B-P18-4.5V
and here is the s/n#: 042312195

the AEM wideband sensor comes stock in the new caddys. it you have one of the sensors the part number on it is a gm part number. I just brought 2 of them for $57.XX each at my local gm dealer

 

Easy to figure out guys.....use a leakdown tester to pressurize the sensor to 30psi.......in your AEM software CD youll find PDF's of each sensor......just cross the voltage readings you get from each sensor at 30psi...it will standout....


Both sensors were sold in brass and SS....

You can cross the part number on the sensor to a stock number...but the Caddy sensor doesnt have the same plug on it...so youll have to change it.....

The AEM sensors are not much higher than the GM part number....Call me for pricing

i usually just plug it into the car and check the wizard... it can only be one of 3 sensors... when you get teh one that reads 0psi you got it

 

If you know you have two different sensors one being the 3.5 bar and one being the 5 bar. All the sensors look the same whether they were the brass sensors or the newer SS ones. From the part number I can read on the brass sensor that is a 5 bar sensor and the other is a 3.5 bar sensor. How do I know and how am I sure I work at AEM.
