Question about throttle postion sensor

I replaced the throttle position sensor and after putting the new one in,when I started the car it would run like the pedal was to the floor and set off the engine light instantly . when I ran the codes it gave me 3 codes they were 22 , 32 and 35 I've already replaced the Map sensor and the idle air control also the EGR and many other parts before the above problem but when I put the old one back in it runs normal until it warms up good then when I stop at a light or any stop the rpm jumps a few times then it stalls but will start right back up

Re: Question about throttle postion sensor

did u do an idle relearn , this is the main cause of stalling at lights or stops with a 3.1

Re: Question about throttle postion sensor

I tested the plug to the TPS and got the 5 volts I'm supposed to get , Then back probed the sensor while turning the butterfly shaft and it say's it should go from 0 - 5 volts when you turn it but mine only went to 4.3 volts

More importantly than max voltage,did the values smoothly steadily increase w/o flat spots or fluctuating up & down.Also,are you getting full travel on the linkage?
