Throttle position sensor fault

I replaced my TPS about 6 weeks ago, check engine was flashing a 24 code.
Seemed to solve the issue. Now it's back. Check engine light on, code is 24.
Checked the connectors. Engine stumbles on acceleration.
I was going to just replace the TPS again, is there anything else to look at.

Well the code doesn't lie. I would guess you just got the crapy end of the stick and your TPS crapped the bed early. What brand did you buy? I bought the napa brand TPS when mine went over a year ago. Two years in may. And it hasn't caused a problem since.

Tps fault will also throw a code with a bad map sensor. Check it with a meter and see if it is bad. If it is then you can warranty it. If it isn't then look at your map and the vacuum lines.

Is this an "over voltage" issue? If yes, really clean all grounds, including verifying the splice(s) at any junctions. The TPS, and several others are just potentiometers, 5 volts on one end, ground on the other. The "signal" is somewhere between the two. The only to get "over voltage" is to have physically broken pot or missing ground. You might even find the original is still good if you still have it. Guess how I came to discover this wonderful peace of advice?
