MAF Sensor Question P0101
#1
![Default](/forum/images/icons/icon1.gif)
Hello All: I have a question about a MAF sensor for a 2005 S-Type Sport. I've replaced it twice and still get the code P0101. I've also replaced the pigtail and inspected the intake tubing for leaks but did not find any. I also have installed a new Jaguar (dealer) air filter. Both MAF sensors that I've used are from AutoZone. I'm a little skeptical about this part since it's remanufactured. I'm also a little hesitant to get one from the Jag dealer since they are 3 times the price and I'm not sure if the sensor is really the problem. I have the JTIS and I have checked the power and ground to the sensor and resistance of the sensor and it seems ok. I also have a scanner and can view the MAF value. I think it is a little low but I'm not sure. Does anyone know what it's supposed to be at idle? Mine is .6 LB/M at idle.
Any suggestions?
Thanks,

I've done the checks on the MAF sensor and everything seems within spec. I've also taken the recommendation of JagV8 and replaced the MAF with one from a wrecker. The P0101 code still comes back. I'm wondering if it's a problem with the throttle body. JTIS says to check these items:
MAF sensor, MAF sensor circuit(s), Blocked air filter, Air intake leak, Engine breather leak, Throttle control malfunction.
I don't think there is a problem with anything MAF related but maybe there is a throttle control malfunction. I believe the P0101 code registers when I'm coming to a stop. Can anyone tell me how to check for throttle control malfunction? I don't get any other codes and the car seems to run fine.

Well, Search basically shows almost no-one's had this ![Frown](https://www.jaguarforums.com/forum/images/smilies/frown.gif)
But yes, it has been fixed by changing the TB (throttle body). Very expensive part so you either want a cheap used one or to do it last of all.
I suppose you could try checking wiring right back to the PCM, but that's a pain to do, too
