Like you said the first two codes are tps related. Check your wire harness and wiring could be shorted to ground or have a broken wire. The third code is for map sensor no response shorted or open circuit.

Have you used a OBD-II scanner to find your issue? The car will help you find out what is needed to fix it. Remember to clear the settings after fixing something. This will help pinpoint your issue. If the same issue arises then the issue is another part. Read those codes supplied with the unit. It will help eliminate possible multiple problems. I have included what the codes mean in the following link How to Read an OBD II Engine Code Best of luck

Yes, a bad map sensor causes poor acceleration, but don't assime the sensor is bad. First check to see if manifold vacuum is getting to the sensor. If yes, next verify that the reference voltage (5vdc on most cars on one of the wires--key on) is getting to the sensor. If yes, then test the sensor by a applying suction to the port and reading the output. You can use your scanner for that.

Easy, find someone that has an OBD2 meter and get the error code # ( an example is Po256) Then plug the code number into google and it will tell you what is wrong.
You have to have a sensor on the engine component for the ck engine lite to come on. Leaking fluid will usually not have a sensor, so this is not the engine light problem.

P0135 bank 1 sensor 1 open or short in wires,bad connections,bad sensor ,or bad ecm. P0141 bank 1 sensor 2 same diag as P0135. P0420 cat below threshold open or short, or faulty Ho2s sensors.you may have several problems. start with sensors circuit if good change sensors if not trace to ecm if reading not right replace ecm if all good replace sensors clear codes retest drive two drive cycles for cat to clear tests. then with no dtcs present test fuel pressure , injectors,then ignition system ,timing valves ,map,maf sensors,throttle sensor,crank sensor cam sensor, compression.

P0500 and P0501 are vehicle speed sensor codes P1529 I can not find in any of my data bases. if you are using a generic scanner/code reader it may be a false display or for some reason it's not listed in my reference materials. I have 4 different sources 1 being factory material?

weeeeiiirrdddd. i have a 2001 hyundia elentra gls, and my third cylinder is misfiring as well. my car also revs constantly on idle and in between shifting. it will flutter between 2-3000 or it will just stay at 5000. i replaced my plugs and wires to no fix with my cylinder. autozone also told me that it sounds like my throttle position sensor needs replaced, but every part they try to sell me will not fit and they swear up and down this is the right part...
