MAP SENSOR VOLTAGE

IDI_AMIN

Anyone know what the voltage should read for the map sensor to test if it is working or not if possible i would like to know voltage if functioning properly and voltage if it is not working properly .
Or if you know of another way to test if its working or not without trying a new sensor of course

obd2 output concerning pressure

30kpa ish at idle and should zero off when at 100% tp and shoot up to 100kpa when you take your foot off the pedal before levelling out at 30kpa ish

I was wrong about kpa decrease with more revs, tis opposite, it should drop to 0 when u take your foot off the gas after revving it, so increase voltage when you rev then near enough 0 volts when you take foot off

so around 1v idle then 4.75 when u plant it

I knew there was something wrong here could almost sense it. P0107 Barometric pressure circuit low which means either Map sensor is fucked or there is something wrong with the wiring i.e. a break or whatever.
This fucking car seems to throw up a new code every week :mad:
