Technical Map sensor

[sirbald]

Hi all can someone kindly point out the location of the map sensor to my grande punto?
Car hesitates when pulling off so I want to replace the sensor

I've added a pic if what could possibly be the map sensor but I don't look nothing like the sensors available to buy for my car. The the bolt is on wrong side so surely that can't be the map sensor?

Any help greatly appreciated

Assuming your Punto is a 1.6 Multijet similar to my 2010 Doblo 1.6 Multijet maybe theses photos will help, The MAP sensor is at the back of the manifold with the top of the yellow locking mechanism of the plug showing, it is held in with a small torx screw, but to remove it you have to release or pull back the plastic around it at one side that clips it into place, it may need a little wd40 to help if the O rings are sticky.
I hope this solves your issue.
If you are able I would appreciate it if you could give me the readings to compare from your MAF sensor plug (on air fliter housing) when unplugged and ignition on but not running as I have a problem where I have a certain amount of black smoke and average performance but on hard acceleration on the dual carriageway goes into limp mode until error code P010F (MAF air A/B correlation) is deleted and sometimes U0001 (Canline Error) I have changed the MAF and MAP sensors in my quest without success so far. The readings I have are No.1 Green and Black wire 12 volts. No.2 Yellow and Grey Earth. No.3 Blue and White 5 Volts. No4 Blue and Green 5 Volts. The last two 3 and 4 change when plugged in and engine running to approx. 2.5 Volts on both wires which seems wrong to me, though I have traced those wires all the way to the ECU with no obvious fault. The third photo is my MAF sensor that I would appreciate the readings from yours for comparison.
