Question about 2005 Ford Mustang
I really need help! I own a 2000 3.6L engine ford mustang with 47,500 miles. I’ve been having power issues where I run my car at sixty and it actually feels like it’s running forty miles an hour. I used my OBD II scanner and received one trouble code: P0121.….In range throttle Position Sensor (TPS) fault. So instead of using a digital multimeter which I currently don’t have I changed the TPS with a new one from Auto Zone, after changing the sensor I turn the key to the on position; engine is not running and the dash bored displayed “Service Engine Soon” the dash was not displaying this light with the old TPS. So I ran the OBD II again and this time it gave me one more code but different from the first trouble code: P0122...Throttle Position sensor TPS/ Padle circuit low input. I assumed it was the cable harness that was bad, I also called Auto Zone and they told me the same thing. So I purchased a new one from my nearest ford dealer and remove the old one. I ran the car once around the block and no lights, I shut off the car/turned it back on and ran it again around the block and the “Service Engine Soon” light came on. I ran the OBD II scan again and it displayed the same trouble code P0122. I do feel that when I’m driving the gas pedal sticks once in a while and if I hit the gas suddenly for more power the engine stalls for a few seconds. Could it be that the throttle valve (padle) is damaged and needs replacement or maybe just an adjustment? I checked in the Haynes manual and it said that the 3.6L and 4.6L engine idle speed is not adjustable and that this procedure requires a special scan tool to extract working parameters (voltage signals) from the EEC-V system while it is running. I feel at a lost!
Make sure you installed the correct TP sensor. If so you may have a bad one. I have gotten bad "new" parts before. If all your problems started with the installed part start there.

Hello! The common point is that all 6 codes are associated with the 5 volt DC reference supply...Tell me exactly what went on with the seat cable repair...Include wire color codes...
