lemmy01 Posted July 14, 2012 Report Share Posted July 14, 2012 There was a wireing diagram by the sensor. As i remember there is a 5 & 12V wire if you choose the right one your wireing looks right for me.(dont use both ,5V or 12v) You could try sucking on the vacline of the sensor and show if the ecu display's it.

Simon Posted July 16, 2012 Report Share Posted July 16, 2012 Check the AN volt error settings. And also that you don't have MAP selected on another AN Volt channel at the same time. Quote Link to comment Share on other sites More sharing options...
koo Posted July 21, 2012 Author Report Share Posted July 21, 2012 after reading about the an volt fault codes i have set high and low warnings to 5.00 and 0.00 respectively. but the map sensor is still not working it is a 4 bar map sensor that was sent with the v88. it was working fine before firmware upgrade? it is set up on an volt 1 calibrated as 4 bar map sensor. any ideas im out of them.

koo Posted July 22, 2012 Author Report Share Posted July 22, 2012 could the upgrade to the new firmware have caused these problems? car was running fine till it was upgraded now it struggles to even start. is there a way to reflash the firmware or wind back the firmware to the previous version. i am at a loss to why this is happening also fixed the an volt errors. so its not in limp mode.

Simon Posted July 22, 2012 Report Share Posted July 22, 2012 If you measure the voltage out of the sensor with a multi meter and see if it changes. If you get no change with pressure then the sensor has failed. The sensor should have a ground 5V and signal. Quote Link to comment Share on other sites More sharing options...
