2001 Camry: No engine response from pedal.

It should be a straight in out replacement.
It will probably take you longer to locate it than to change it.
(In the unlikely event of any calibration being needed the engine management system (EMS) should take care of it, especially if you dissconnect the battery overnight, that might help the EMS to reset to default values)

What evidence suggests to you that the TPS is defective?

Have you examined the vehicle's data stream statically and dynamically?

Have you checked for specific trouble codes?

Simple answer (for those without shop/dealership facilities AND know-how): It's not a DYI task - either diagnostic or TPS fault repair.

Also, "not response from pedal" (while intuitively "seems-right") is not typically a TPS-fault failure mode. More typically: Engine "start-stall"...progressing to engine "no start." (Sensing of throttle position - without slop - ... critical for computer monitoring/control...not so much for throttling, don't you see.

Before taking it to repair shop...go to first intuitive (KISS solution place): pedal-to-throttle cabling/linkage. (Your statement that...no engine response indicates that car just sits there idling but is not drivable (can't accellerate)...or can't slow down other than with brakes and engine kill (or running into something).

Final update. As it turns out my daughter left the lights on. When she had college security help jump the car it must of blown a fuse that was under the hood. The schematics only list it as CPS. After checking all the fuses this last fuse was blown. I replaced fuse and accelerator work normally. Thanks everyone for your help.

Update appreciated. Thanks from (I presume) all of us.

Advise daughter read manual on how (and, inferentially, how not) to receive or give boost with battery jumper cables; never leave it to KK (Kampus Kops) and such.

CPS: sounds like "computer protection system"...blows fuse to interrupt over current (thus isolating computer criticals) due to battery boosting done incorrectly...or correctly(?). (If fast blow fuse, it could be due simply to a momentary bump or misplacement of cable clamps.)
