I am having a persistent issue with my MAP sensor reading on my 1990 Eagle Talon.
I have tested 2 confirmed working AEM 5 bar sensors. We have checked the wiring a have confirmed 5 volts and have a good ground with a multimeter and test light.
I am getting a consistent fault code 14 for an error low value. When the error low value is set to 0.00 from the default 0.05V the car will refuse to start and run. With the error low value set to 0.05v the sensor will show 1.00v in the runtime values menu and MAP (psi) of 14.5 and a MGP of 0.00. With the car running these values do not change. When the runtime error value is set to 0.00v the sensor shows no voltage in the runtime values menu and the MGP and MAP values invert and will read 14.5 for MGP and 0.00 for the MAP.
I am stumped as to what the issue can be as both MAP sensors I have tried are working and the wiring is correct.
I have attached a copy of my tune file as well as screenshots of my runtime values with both error value settings.
Hopefully the tuning wizards here can help.
