P0237 Turbo boost sensor A circuit low
 

need your help guys

car drives fine, check engine light went on and then off the next day, mech scanned and came up with that (guess its stored in memory)

Car had some surging idle, now its steady, but i think i feel some surging still...

what should i do ?

read somewhere that volvo refers to it as a MAP sensor, is this the same thing ?

who's got vadis ? i dont have it on this computer, i just moved and its on a disc somewhere in a box that i cannot find yet... plz let me know ...

this is ridiculous, i keep replying to my own thread
item #5 called Intake Manifold Pressure Sensor, is this what i need to buy ?
looks like its easy to replace, am i right ?
Attachment 22120

for those who are searching this thread like years after i posted this - yes the boost sensor was the culprit, so if you are sitting at a red light and all the sudden your rpm dips down once or twice, or if you are getting a jerky pedal reaction upon acceleration accompanied with slight vibration along with the code P0237 then yes - this is the sensor to change for sure, car feels like new now, got all my power back, lots of torque, i go up hills at 1500 - 1700 rpm @ 80 Km/h. i think the sensor can be cleaned, cause after i took it out and saw the little hole that can easily plug up with dirt and oil its kinda obvious, i think this has been happening for a while and i have always felt some slight rpm dips and jerkiness that is now gone...

mine is at the shop as we speak right now

^for...?

for this very code p00237. How much is the part usually?

Sorry somehow I missed this post.

its ok you cant get to them all, it was frustrating , but i think its all good now
the part is about $135 canadian + tax at the dealer, i tried searching like 6 different websites and noone of them had it in stock,

i got a discount atthe dealer cause the guy was nice, i got it for 110 + tax, online i think its about 80-100 canadian

the sensor is in an easy location to change but it still gave me trouble at the plastic clips that hold it are so friggin tight it took me almost an hour to change, but at least i did no need a mechanics ;-)

interesting enough I have to do this one bymyself, What exactly has to be removed in order to access the area I need to get too?

Will this roughly take an hour to do? Basic tools needed?

is that a fair price on the part for it, if so I will go ahead and buy it:

Thanks

thats a damn good price for a bosch oem part for a volvo, i paid more than that

once you get your hands in there you will see what needs to be removed, its just a little hose that needs to be put aside

you will need a long flat screwdriver, or two, and i would use some kind of thin (not latex or nitrile) gloves like rubber dipped for better grip,,,

other than that, good luck and dont break the tabs that gold the sensor!!!

shocking how easy this is to get too, I tried to clean it with carb cleaner, it didnt work. So I ordered the new sensor.

also found a used sensor for 24$? would any suggest that this be okay?

cannot say, it could be just as broken as your old one

sorry just saw this - on an S60 with no tools the swap took me about 40 seconds including opening the hood.

I wouldn't buy any sensor used, but thats just me.

i ended up gettin it for 17$ hopefully it will be oka lol

I have very less idea on it. Actually how much is the part is...?
By John,

i think i paid 40 for it brand new @ the dealer.

really? everywhere I looked it was 79$ plus... lol... and at autozone they wanted 96$, so I thought they probably wanted more if I went to the delearship...

i also have a VERY good relationship with my dealer - they do give me a break on things from time to time.

its 125 + tax at any canadian dealer actually, it can be had for less online you you can find one in stock, and buying a used sensor its like buying something in a black box and you dont know whats inside...

P0237 MAP Turbo/supercharger boost sensor.A circuit low Circuit open,short to ground,faulty sensor.

isnt that the title of the thread ?

Pretty sure it's spam. Disregard.

The user has one more day to remove the links in sig before they get an infraction.

hehe.... I get the car all apart today nice and easily remove the clips holding the sensor and open the box to find that this is not the correct part :( lol... my luck... picture was taken from my cell phone lol.... has this information on it - Volvo 1275638, then under this it has these numbers on it - 499500-0050, then under this it has written 5V, Denso japan ...

definitely wrong item, i have the old one still in the garage, i might be able to take a pic later

i bought the right one from Volvo delearship today, I searched online and found a 20% coupon and ended up getting the sensor for 72$ today. any idea what that is hahaa..

P0236 P0237 Turbo boost sensor A circuit low
 

When it says "A circuit low" it's the MAP sensor measuring the turbocharger intake pressure. It is dead, or no power getting through it.

Check physical connection, clean the electrical contacts. If no different replace the part. Simple.

Bosch 0261230029 MAP sensor. Just google that number.

Got mine from RockAuto for $45 USD. 2 min fix. Rides smooth and fast pickup with better fuel consumption now. Was like this when I bought it. Replaced part and HIYAAAH love it even more. (2002 S80 T6).

Good luck
