2007 Suzuki XL7 - Error code reads p0122 and the computer in the dash reads Engine Hot- A/C off. It turned over earlier but Car wont start now. Battery is new, all fluid levels ok. AND... can anyone tell me a PART NUMBER to search for to replace the TPS? or a simple step by step on how to ADJUST it?

That TPS isn't stopping the engine from cranking. If you got it that hot, you may have done some serious damage.

The car did not get hot its outside in winter here 10 outside. Nothing "overheated" its a TPS throttle error not an overheating issue.

The throttle body assembly contains 2 throttle position (TP) sensors. The TP sensors are mounted to the throttle body assembly and are not serviceable.
If there is a condition with the TP sensors the ECM defaults to reduced power mode for the entire ignition cycle, even if the condition is corrected.
TAC System Default Actions/Reduce Power Modes
There are 2 reduce power modes that the engine control module (ECM) can default to if an error is detected in the throttle actuator control (TAC) system. If an accelerator pedal position (APP) sensor 1 or APP sensor 2 circuit fault, throttle position (TP) sensor 2 circuit fault, or if a TP sensor 1 circuit fault is detected with some APP angle, the ECM goes into one of the 2 reduce power modes. In this mode, the engine torque is limited so that the vehicle cannot reach speeds of more than 100 km/h (60 mph). The ECM remains in this reduce power mode during the entire ignition cycle even if the fault is corrected.If there is a condition with the throttle actuator control circuits, throttle actuator command vs actual position fault, return spring check fault, or a TP sensor 1 circuit fault, the ECM goes into the other reduce engine power mode. In this mode, the engine speed is limited to 2,500 RPM and the 3-6 fuel injectors are randomly turned OFF. At this time the Reduced Power indicator is commanded ON. The ECM remains in the reduce power mode during the entire ignition cycle even if the fault is corrected. Observe, if a TP sensor 1 or throttle actuator control circuit fault is present at the time the vehicle is at idle, with no accelerator pedal angle, the engine may stall.
Doesn't state anything in those quotes about reduce power mode causing a no start.
Looks like you would need to replace the entire throttle body for the TPS. Maybe you should do some diagnosis before condemning the throttle body because of a circuit code. Just a suggestion.
Throttle body is $356 from the dealer. Part # 1340078J00
