I just changed the throttle position sensor and it is still shutting off when i turn and put it in park . On a 1996 chevy lumina

During replacement of key components of the engine management system including the battery the set points of the computer need to be relearned. The computer algorithms are adaptive and the idle air setting is part of that. The TPS provides the throttle position information to the computer .

It usually takes up to 8 miles of driving for the adapting process to settle in. In your specific case it is not possible to know at this point if this is the cause of the stalling. If the engine did not stall before the replacement than it likely is the problem.(the car needs to be driven to allow for the adaptive controls to relearn the idle set points) You need to be patient and let the car relearn the idle set points. If the car had been stalling previously then you can only try driving the car to see if the new TPS component has resolved the issue.

Do i need to relearn the tps on a 1999 vw jetta

Unhook battery, press brakes to de-power everything. Leave unhooked for half hour or more.

Re-connect the battery. Turn key to on position. Do not start the car... just to on. Don't touch the gas pedal at all. Leave for ~10-20min.

Turn key straight to start and start the car. Do not touch the gas pedal. Let idle for ~10min without touching anything.

Turn off car. Restart, drive. It might take a few heat cycles and a bit of driving before the ECU 'learns' everything over again.

Pcm relearn

what large topic. and wow, not even a FUNCTION STATED
just the WHOLE PCM,.
no symptoms, no issues, just that.
not sure what engine you have there, and matters !!!
most PCM's relearn EVERYTHING after you pull the battery
connections or the PCM memory fuse. IOD fuse.

dont pull the battery, or lose radio passcodes. (bricks IT or NAV bricked, if opted)
lots of learn, paths.
fuel trim? ( does o automatically as does spark)
spark advance, and knock data?
transmissions all have learn mode, and do so automatically when reset.
now the last one, some cars, the TB (throttle ) body must be relearned, some are auto learn others not.
aka: throttle by wire ,relearn.
did you replace something (my other shoe drops......)

did you first scan the PCM and see if there are issues.
if not, why not, why work blind>?

there are other learns
seat position (guessing BCM)_
pedal position relearn, omg.
Sentry Key "Customer Learn" Mode
transmission quick learn or drive learn (read the FSM yet?)
chapter 8e-290 + all those learn steps for trans, takes no tools.
RTM? yet?

instrument cluster learn mode? Odometer?
At the garage door opener receiver (motor-head unit) in the garage, locate the 9learn9 or 9smart9 button.
sun roof relearn?

TPS learn(excepted)
"Is the voltage reading within the listed specification when the
jumper wire is installed?
Yes >> Replace the Throttle Body Assembly. Disconnect the Battery
when replacing the Throttle Body Assembly. After
installation is complete, use a scan tool and select the
ETC RELEARN function.

No >> Go To 4
NOTE: Remove the jumper wire before continuing."

ill stop here, (i scanned the whole FSM for you on LEARN)
these newer cars the PCm .,BCM and other modules work on cooperative modes. Ill be the last to ever say , where learn data i stored, that i below my paygrade (retired and zero) LOL !

why not post something more focused.
I'm considering a new TB.
what do I need to know.?

How to tell if tps is going bad on 2005 murano rpms jump up and down took it to dealership and at first the tech said he has never seen this before then they said throttle body needed to be cleaned and...

So did they clean the throttle body? It could be tps or iacv also. There are many things it could be. Is the check engine light on? If they reset the computer they should have seen what codes were present.

What is a tps sensor and what does it mean to be re-flashed.

TPS is Throttle Position Sensor and Its Purpose is to Tell ECM What You Are Demanding of the Gas Pedal , it Senses Where the Gas Pedal is --
Reflash= Relearn that is When A NEw Sensor or ECM Controlled Component is Installed and ECM Must Relearn the Electrical Values of Components. To Relearn you Must Do the Fallowing.
Turn Ignition Switch On and Leive it on for 10 minutes then turn it off for 30 Seconds then turn it back on for 10 mins Do this a total of 3 times totaling 30 minutes ALL Without Starting Engine Just Turning KEY to ON Position.

Check the throttle position sensor"tps",or the idle air control "iac" by chance did the battery go dead or was unhooked?
if so the ecu was reset and needs to relearn idle settings by just keeping it running for a few minutes
