    If you would be so kind as to click the "answer this question" button, and post the year, make, and model of your vehicle, we could answer your question. Computer codes change from brand to brand, and also change from pre-1995 OBD 1 to post-1996 OBD II emission control systems.

    There is no P1129 code in my list of Jeep OBD II codes; but there is a P1192 code. If someone misread or transposed the two code digits; the P1192 code means that the voltage input at the inlet air temperature sensor is below the minimum allowable limit. By the way; if this vehicle has had one of those mislabeled aftermarket "performance chips" wired into the IAT sensor circuit; that would probably cause this code to set. The solution would be to remove that illegal device.
