Hi I have the following setup on a 2007 Lotus Exige S
1. MX2E
2. Monkeywrench racing sandwich plate
3. 150 psi AiM sensor

its always showing 130-150 even when car is off or at idle

any thoughts?
thank you

Bad gage or sensor? Maybe the wire is grounding out.

got a new sensor from AiM
so i have ruled that out
everything is insulated
everything else works on MX2E digital cluster.
where can I check for bad ground?
thanks much

Is it a one wire sensor? if it is you might have a ground issue, you can check the resistance between the body of the sensor and a good ground point like the engine ground strap it should be no more than a few Ohms

If its the AiM 4 wire sensor and you have already replaced it it you either have a wiring issue or possibly the analog input on the dash is messed up. I am not familiar with the dash but it is possible to wire the sensor up into a different input and check to see if that fixes the issue?

i think it is 4 wire AiM sensor since there are 4 prongs in each plug.
bad extension cable?
I guess I will try swapping the channels in the channel expansion and see if i still get erroneously high oil pressure
thank you

If you still have the issue when you swap to another channel, try the sensor directly connected to the dash it should read 0 and if that works your extension cable is suspect.

Can you list the AiM part numbers of the sensor and any extension cable(s) you used (between the sensor and the channel expansion unit and/or between the channel expansion and the dash)?

Do you still have the CE going directly to the dash, or is there a data hub between the CE and the dash?

If he's using 0-150 AIM oil pressure sensor with 4 prongs, there should be data hub between CE and the dash.

I have same setup and reading 0psi when car is off and 68~71psi WOT.
OEM oil pressure reads 3.63 bar from EMU black ecu on track.

I agree, I installed same on my '08 Exige, including the data hub (and a SmartyCam), and oil temp and pressure sensors connected to the Channel Expansion (all working fine). The reason I asked is because the OP said that he couldn't get the data hub (and GPS) to work so he connected the CE directly to the dash (link to post).

You’ve selected the correct sensor on race studio? By default mine were not the Aim ones and I had to find them
