1st rule of trouble shooting.
Resolve you're codes before trying to fix anything.

1 code can make you're ecu throw other codes which are not actually there.

Concerning you're tps, you need a voltmeter & a helms or haynes manual Or you can just check you're tps sensor for 5v at wot on the middle wire of the plug.

I do not remember what the manual says to do to test a tps. But I believe that is the proper way to test it.

You're speed sensor might be bad... Check you're wiring & again get a manual & read how to trouble shoot it using a voltmeter.

Voltmeters are handy tools

Good luck.
