Barometric Sensor Issues

[Boddie]

I keep getting the check engine light every time I turn on my vehicle. It comes on immediately after being reset. It gives code 25 which is suppose to be the barometric pressure sensor. After replacing the entire MAF including the barometric pressure sensor with a known good one, the light still came on after resetting it. I took it to a shop to do some measurements on it since I do not have the proper equipment. The said the 5 volt reference signal is good and the sensor signal is 3.8 volts at the computer. They suggested I get teh ECU looked at.

The issue with that is I literally just got the ECU back from ECMTuning where they tested it and replaced the Boost Control solenoid driver IC106 (which I am not sure was necessary considering I use a MBC) and all the capacitors.

I am not sure what else to do, so any help would be great!

You can check the wiring, swap out and test another ECU, and maybe give the guys a call back at Ecm link and see what they have to say.

Do you have the ability to log and see what the baro reading is??

No I do not have any logging tools
