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.

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.

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.

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.
