Surely been discussed before. But is the MAP and TMAP Sensor for a R53 the SAME part number or not? MiniMania website says they are unique, but look identical. And some eBay postings just say buy two MAP sensors.

Just replaced the MAP sensor by the AirBox (Delphi MAP Sensor PS10133), And STILL getting P0107 and P1688 codes with massive "limp mode".. Hoping its the 2nd sensor under/front of the Intercooler that is the culprit???

Thank You!

If memory serves me correct when I replaced both my sensors they were different part numbers . I believe one uses 3 wires and the other 4 wires , or something along those lines .
Also I did go oem on both the sensors as it was suggested.

 

They are different.
And not interchangeable.

 

I do not remember correctly but just like what Ngtphantom said, one has 3 pins and the other has 4 pins. They both have the same numbers for about 75% of their part number but I think down to the last 2-3 numbers its different. As I said earlier I do not remember exact numbers and stuff. Beware you do not plug a sensor in the incorrect location and possibly damage pins.
Good luck!

 

If you'd like I can verify which part # goes where.. we have a map and a tmap. Though there both constantly referred to wrong.. the tmap measures both psi and temp and its located in the intake Manifold by the radiator and the map sensor is located to the left of the intake tube up towards the airbox kinda.. I can't think if the #s off hand but the last 4 digits of the part # determines where it will go..
I highly HIGHLY suggest avoiding non oem brands of tmap or map sensors. I've tried numerous brands and if they work they only work for a short time and either completely fail or loose accuracy and will throw missfire codes ect..
try cleaning the sensor with mafs cleaner spray NOT brake cleaner or carb cleaner and gently use a qtip on the exposed filament and rub off any oil residue that may have built up and baked on.

 

Thank you everyone! Replaced MAP and Battery. And still was in LIMP mode BAD! Bought the $160 buck TMAP sensor today, and back in business! They are both 4-Pin connectors, and look EXACTLY the same as far as I can see. Part number is different.

Front/Manifold is: 12140872679
Airbox/Rear is: 12140872648

But visually I have no idea the difference. Must be all internal differences...

And not to knock on wood...think may have fixed by cold start idle hesitation....

 

Yes I believe those are the part number . Glad you got it going! As for the difference between both the bodies look very similar. Where the difference lies is at the harness connectors to the sensor. One will have 3 wires and the other 4 wires I think, therefore taking different readings .

 

12140872679 is 2,5bar sensor, 12140872648 is atm sensor.

 

Probably applies to all supercharged Minis.

No codes, no MIL. Car bogged/stumbled during acceleration
but performed well at higher RPM. I'm thinking vacuum leak.
Scan tool showed 11 inHg vacuum at idle, but a mechanical
gauge showed 15 inches. There are two MAP sensors, one in
the intake manifold, one in the intake tube between the
supercharger and throttle body. The PCM uses these two
signals (plus RPM) to calculate intake airflow. Removed the
sensors and connected a mighty vac to each one to see if the
scan tool readings change. Both sensors send a signal but
the upstream (intake tube) sensor did not hold vacuum.
Replaced that sensor and fixed the problem, vacuum is now 17 inches.

The sensor SIGNAL did not fail so there was no code, no MIL, but it
definitely was the source of a vacuum leak. Live and learn.
