Baro reading and P0101 MAF DTC

Adrian2012....I know I prattle on about the virtues of All Grand Cherokee and their limitless knowledge on our beasts...but...its ALWAYS worth a call to them to gain clarity on just what your dealing with....Tam IS the man and is more than willing to give free...YEP FREE...advise/support/guidance/problem solve over the phone....free advise never hurts...especially when its coming from GENUINE experts

Well Farwest's pic shows that your sensor is original and since I have revisted this topic I run a check on my numbers, lo and behold I find the Bosch part number stamped on my MAP comes up as a fuel sensor in the Bosch catalogue while the Jeep number comes up as the MAP sensor, the Bosch number on yours comes up with a MAP sensor that going by the schematics is the same sensor as mine, most of these sensors are generic only the housing changes to cause confusion......... research is crucial along with cross referencing, NTK do good sensors as well.

So I would be having a look at the connections, make sure the pins haven't been pushed in or bent over which often happens, give it a squirt of juice as well, make sure you can see daylight in the sensor housing, if all good and its still playing up whatever its doing then might be stuffed.... though if you have a MAP reading of 101kpa then can't see anything wrong really..... on these readers not all functions are available on all engines so you will have blanks or base line figures......

Here's a pic of mine while the Bosch number is wrong the F number is Fiat and it cross references and matches the Jeep 68211211AA

How do you blokes have such clean engine compartments ???....Christ, mine wasnt that clean when I picked it up from the Auction House....let alone after blasting down dirt tracks going fishing....NEVER going to do what I have done in the past n attack the engine bay with the pressure wash at the Carwash with 2x cans of WD40 (dont ask why 2...you can guess what happened one time) on standby to get it started after its 'spruce up'....jus jealous is alls Im sayin

Hi Farwest,

Very interesting. If you have a scanner can you tell me if yours is measuring Baro?

thanks
Adrian

Hi Drover,
I saw that Automotive Superstore page and if you check the compatibility then Jeep isn't covered. I also went to Bosch and for that part number Jeep is also not listed.
Hard to get accurate info nowadays.

thanks
Adrian

Adrian...I dont have a scanner...at this stage....I have been lucky enough to not require one...sorry.....Bob may have one and Grippy is another 11-13 owner that I know does have one and is tech savvy...Hey Grippy...leave those kids alone (Pink Floyd reference) and help if you can
