Chrysler Repair: Sebring jxi: Codes 0112, 1796, transmission controller, hall effect sensor


Question
QUESTION: I have two codes that came up: 0112 and 1796 could you please tell me what they are and mean, I know the 0112 is something with the air intake and I replaced it code is still there even after dislocating the battery. please advise.

ANSWER: Hi Robert,
You didn't tell me the year of the Sebring so it is not possible to be specific but the 0112 is indeed about the input air temp sensor voltage being too low. If you replaced the sensor then that would ideally eliminate the possiblility of a short in the sensor itself. When the voltage is low enough to set this code it usually means the signal wire is shorted to ground or the sensor is internally shorted to ground. Let me know the year model and I can tell you exactly. In the '00 model thae wire is black/red and goes to pin 37 of the plug at the powertrain computer that hold wires 1-40. You could unplug the sensor and the 1-40 plug to see if you then find the wire to be shorted to ground or not. If not, then maybe the code is 'stale' and you have it fixed but it just hasn't erased yet. Along the way the code erasure process required the intervention of the diagnostic code reader rather than simply disconnecting the battery, but it will self-erase after 50 key on-off cycles if the problem no longer is present.
The 1796 is about the autostick function of the transmssion and it says there is something wrong with the circuit from the switch to the tcm. In the '00 model that function's switch has 4 pins: 4 red/violet is a 12v input, 3 is a ground wire black, 2 is light green/light blue and goes to pin 5 at the transmission controller, and 1 is yellow/light blue and goes to pin 44 for the transmission controller. You could verify those wires, and check that the two on pins 2 and 1 are not shorted to ground when you have both plugs removed. If all that check then you would probably need to change the autostick control switch which is an electronic device called a hall effect sensor and is subject to failure at some point in time.

QUESTION: The year of my Sebring is 1997, and please clarify the info with the year of the car, and if it is still the autostick function then where is it located, and thank you for your time I appreciate it

Answer
Hi Robert,
If you have the autostick feature it would be a positition choice on the gear shift mechanism (and would be indicated either on he shifter or its 'surround') which allows you to control when the gear change occurs by moving the shifter to the left or the right for down and up shifting at will. If you had it, it would also show up as an indication of that and also the gear selected, on the cluster, when your tried to use it. If it doesn't work and you verify the wires as I described then it is broken. According to the manual that requires replacing the gear shift mechanism as parts for that specific option evidentally aren't sold separately. This is from my '98 manual. Let me know if you want to take out the mechanism and I could copy the pages that show how to do that from my '98 manual. It costs me 10 cents per side plus the postage.
It may be the case, even in '97 that you have to erase the codes by means of a diagnostic readout box. I would believe that you could go to Autozone parts store and ask for them to erase the codes as they will also do a code readout for free. That way you should be able to 'clean the slate' and then see what comes up again. I do believe that the self-erasure will occur as well if you are willing to await that outcome if the problem is repaired.
All the wires I referred to from the '00 manual are also shown in the '98 manual which should be identical to those in your '97.
