lostsoul Posted May 10, 2020 Report Share Posted May 10, 2020 Getting a "operation failed" , will read +/- 5 kpa message when trying to calibrate the MAP Sensor ?? Have checked connection. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2020 Report Share Posted May 10, 2020 What does the BAP read compared to MAP? It must be within 5Kpa otherwise it means your map sensor cal is wrong. Quote Link to comment Share on other sites More sharing options...
lostsoul Posted May 10, 2020 Author Report Share Posted May 10, 2020 The BAP = 100kpa and MAP = 95 kpa. attached is the MAP Sensor Calibration. Has been working fine until yesterday. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 10, 2020 Report Share Posted May 10, 2020 has condensation gotten into the map sensor through the vacuum piping? Quote Link to comment Share on other sites More sharing options...
lostsoul Posted May 10, 2020 Author Report Share Posted May 10, 2020 Don't know ... the car was run only the day before and everything seemed alright then. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2020 Report Share Posted May 10, 2020 It is likely you are just a couple of tenths of a kpa outside of the 5kpa tolerance allowed. What you could try is sucking on the MAP hose just a fraction to get it within the 5kpa tolerance then hit the calibrate button. That will then offset the calibration a little so after that you then do the cal once more but without sucking on it this time. Quote Link to comment Share on other sites More sharing options...
lostsoul Posted May 11, 2020 Author Report Share Posted May 11, 2020 I thought I would try it once more before trying the "sucky" thing ..... calibration was successful, I am pretty certain all things cars got their temperaments from the same place as Cat's.
