I just installed a new TPS on my 2001 Ford Taurus SEL, DOHC w/ 25,000 miles. Now I'm getting a DTC "P0122 Throttle Position Sensor/Switch A Circuit Low Input" Can someone please explain to me what does this mean? Thanks

It means the PCM detected the TP sensor signal was less than the minimum calibrated limit of 0.17v.
Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage. Check your wiring first then post back on how to check voltages.
If you have a scan tool you can check if it is out of adjustment pretty easily by looking at the throttle percentage. If it's less than 3.4% than it's out of adjustment.
