Lemonslice22 Posted July 17, 2018 Report Share Posted July 17, 2018 Hi im trying to calibrate my MAP sensor which is a link 3 bar using stock MAP wiring. Ive selected the link 3 bar sensor from the drop down menu but when trying to calibrate it i have a fault - MAP Sensor Calibration command failed: Current map <5kpa or > 5kpa of baro reading. It says its using AN Volt 1 for MAP sensor. Can anyone tell some things to check or change in order to get this to calibrate. Thanks.

Adamw Posted July 18, 2018 Report Share Posted July 18, 2018 (edited) To give us some clues what the problem is, go to AN Volt 1 settings, change the error low to 0.0V and the error high to 5.0V. With engine not running, open up runtimes screen (F12) and have a look at the analog tab as shown below. Tell us what voltage is showing on AN 1. With the 3 bar sensor it should be about 1.62V at 100Kpa. Edited July 18, 2018 by Adamw Typo Quote Link to comment Share on other sites More sharing options...
Lemonslice22 Posted July 19, 2018 Author Report Share Posted July 19, 2018 Hi ive just done as you have said and the voltage is 2.79 Quote Link to comment Share on other sites More sharing options...
rrob Posted July 19, 2018 Report Share Posted July 19, 2018 Try 2 bar, and see if the readings are realistic. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 19, 2018 Report Share Posted July 19, 2018 The voltage you are seeing there matches the stock Supra MAP sensor. Set MAP sensor type to "ST185" and the calibration will work. What made you think you have a 3Bar link sensor? Or maybe it has been wired to a different input, and you still have the stock one in place at the same time?

Lemonslice22 Posted July 20, 2018 Author Report Share Posted July 20, 2018 I replaced the origional with a link 3 bar MAP sensor myself. The stock one is in my tool box. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2018 Report Share Posted July 20, 2018 Maybe you have the pinout wrong then. Got a photo? If you suck/blow on the hose does the voltage/map change? Quote Link to comment Share on other sites More sharing options...
Lemonslice22 Posted July 20, 2018 Author Report Share Posted July 20, 2018 Il check this over in the morning thanks. Quote Link to comment Share on other sites More sharing options...
