Fg Map Sensor - Is It 1 Bar? If So What Happens If You Go Over 1 Bar (


Recommended Posts

So I am getting code p0236 - boost sensor circuit out of range.

I was thinking that it was probably just a faulty sensor as it occurs after I reach about 18 psi or more(have a gtx set up) and that it wasnt reading the high PSI correctly.

So I ordered a new one thinking that might fix it (I havnt picked it up or paid for it yet).

but now I discover on bosch's web page that the FG map sensor is part number 0 261 230 020 which max's out at 115 kpa (or 16 psi at 4.65 volt). I guess theoretically you might get to use the extra .35 volt (total 5 volt) but even then that would only bring you up to just over 17 psi.

So what happens if you go over this amount - does the maf sensor take over?

I am now thinking that the reason my car throws the p0236 code is it max's out the Map sensor range. Seeing that there are alot of cars running more than 17 psi, do/are tuners just able to stop that code from registering?

when mine throws the code, the car obviously goes into some special limpy mode and surges/pulses on light throttle. if I clear it it goes back to normal straight away.

mucho grassy arse for any advice

Nice, So is it trade in time. A mate of mine went halves in a crate LSA, he kept the blower and extras and the other guy got the engine. Blower for 6K, RTR.
