were can i find this on my carisma? looks like the fault code 25 means theres something wrong with this?

The Barometric Pressure Sensor /Manifold Absolute Pressure is usually located on teh upper portion of the intake plenum near the throttle body on these models. BARO is usually written on top of teh sensor in small letters, it isnt big at all the sensor.

mitsy told me baro sensor is built in to airflow meter ? is ths correct

That is incorrect. The Barometric pressure sensor /Manifold absolute pressure sensor . They measure decrease in pressure(vacuum ) within the intake manifold , while the Air Flow Meter measures the amount of air flowing into the engine through the intake throttle body . One measures air pressure drop (BARO/MAP) while the other measures amount of air/air flow . They both provide readings to teh ECU to give the best fuel to air ratio. Picture of Mine on my intake plenum is shown

ive replaced the airflow meter also cleaned the throttle bodie housing my car is still limiting out at 3000 rpm and the management light is still on

the error code is 25 baro.pre.snr..
ive located it i think its located were you said but looks different to yours it as 2 pipes coming out of it..
if i replaced this would all be fine and would one of any model work ...

That is a vacuum modulator. It most likely be for the fuel pressure regulator, or EGR valve, the valve shown open ans allows vacuum to flow to wutever source is needed for operation. if possible take a picture of the intake plenum runner , . Wut is possibly happening is that the computer is reading a big variance between intake side pressure and the air that the mass air flow is reading as actually going in and the throttle angle reading frum the TPS sensor. being there is such a vary between teh readings fuel spray and ignition timing is hindered engine performance. wut year and engine size might i ad, i may be ablt to tell yu its exact location.

the bit in the photo is found were your picture is ?

its a carisma 1.8GDI 5dr saloon automatic 2000 model i cant take pics its too dark outside i will update in the morninig

your a star thanks for the help not getting much from uk dealers..
cant get a manual for my model?

OKies i have the answer , turns out that , turn in point in teh manual the Barometric Pressure sensor is located in the Nozzle section of the Air Flow Meter , , downside is its onlee sold as a whole unit <_<

Yeah That really sucks . Though Most Mitsubishi products using the 4G9 series of engines , Colt , Carisma etc between 97.5 up to 2005 use this type of AFM > though it was a huge problem that Mitsubishi liek their other models moved the Baro sensor back on the intake plenum behind the throttle body as other models to which it worked better and was less prone to failure. 1.8 and 2.0 4G9 Mitsubishi engined cars will have the same compatible AFM it seems , i have run a check on it , 98-01 Pajero Sport and Shogun Sport with the 2.4 will also work it seems

so it doesnt need to be gdi model?
i can go to scrap yard in morning..

Frum wut ive looked thru it mad no diffrent designation to being diffrent frum gasoline direct injection or not. altho most of the 1.8 and 2.0 4G9 series around that year are GDI . Though it specified no differance between GDI and not and gave models up from 97 to 2005 all 1.8 and 2.0 GDI and a side not that non GDI numbers superced to the same number , as well as the year specified Shogun and Pajero Sport . So ues a scrap lot should have wut yur looking for easilly , when there look for younger model autos that have the 1.8 and 2.0 , there was a revision to the unit in 2002 , so 2002-2005 model AFM's i think fixed or were revised because of the issue of early failure.

so i should look for 97-05 colt,pajero,anything mitsubishi and as long as part number matches on MAF it should work?

Okies your engine is im sure a 4G93 1.8 SOCH GDI correct? the 4G94 is a 2.0 liter version of yur engine.

1996-2005 Carisma ,Colt , Lancer (non Evo)
Any of these vehicles using 1.8 and 2.0 GDI and Non , it stipulated that the number for the non GDI is superceded to the GDI one meaning its the same . these models are easy to designate , teh engine rather 1.8 or 2.0 , teh valve cover will look exactlly teh same through these years , the intake will look a little diffrent on 02 up models but the AFM is the same til 05. Just look on the firewall behind the engine where the Mitsubishi tag is , where it says engine it will say 4G93 or 4G94.

On the Shogun Sport , it shows that the 98-01 2.4 liter engined SWB is the same. On the Pajero Sport all it has to have is the 2.4 petrol engine
Some models of the Later Colts and Carisma have superceded numbers but are the same AFM in teh years shown. But yu can always take the number of yurs to match if yu like. But there are many Mitsubishi models that use the 4G9 1.8/2.0 with GDI so it should not be hard to find, just look for wut ive showed .

your the man great help il keep ya posted later today

mods should pin this thread...

No problem at all , yur welcome , ive compiled models using the 4G93 and 4G94 to narrow down wut yur looking for.

1996-2005
Mitsubishi Galant
Mitsubishi Legnum
Mitsubishi Aspire
Mitsubishi RVR
Mitsubishi Pajero iO
Mitsubishi Carisma
Mitsubishi Space Star
Mitsubishi Lancer
Mitsubishi Colt

1998-2001 4G64 2.4
Mitsubishi Shogun SWB
Mitsubishi Pajero SWB/LWB

ok just waiting for fitter to come out..
been to scrap yard bought 2
98 carisma 1.8glx
99 carisma
both look same as the 1 on the car just part numbers are different il continue thread when fitter as gone..

sorry m8 still doing same..
changed the air flow sensor with 5 different ones and its still the bloody same

the tech came out and ran the fault finder and it came up with immob.comm error surley this wouldnt make it limit out at 3000rpm

the baro prs snsr error as fanished ?
