The throttle position sensor, TPS, tells the engine control module,ECM where the throttle blade is. It is the primary way that the ECM knows what you want out of the engine. There is a backup system if the TPS fails, but it is not as efficient as the TPS.
So what does happen. The engine will not be as responsive to the throttle as it should be.
When you accelerate there may be a pause while the ECM realizes what you did. If you let off the of the accelerator the engine may take a few moments to return to idle or may idle rough and have a minor surge. It will ultimately return to idle. The engine will still run, but will be sluggish and lose its pep.

If check engine goes on can this be the throttle body?
Yes, particularly the throttle position sensor. But it could also be literally thousands of other things.
Where is it located tps 02 Jeep Grand Cherokee 4.0?
The throttle position sensor is mounted to the throttle body. It is located opposite of where the throttle cable goes onto the throttle body.
What is tp sensor on 2000 dodge neon?
it is a throttle position sensor, should be located on the rubber part that goes to your air filter box.
Where is throttle position sensor 2003 dodge ram?
If it is an 3.7L or 4.7L engine it is on the throttle body mounted on the side. If it is a hemi engine there are two throttle position sensors. The throttle body is electronic. There is a position sensor mounted underneath the battery hidden behind a cover. The accelerator cable goes from the gas pedal to this sensor. This sensor sends info to the PCM (powertrain control mondule). There is also another position sensor inside the electronic throttle body which tells the PCM what position the throttle plate is at. These throttle bodies on the hemi engines become dirty and cause codes like a P2175 and 2106. It will also make the ETC light flash, and cause low acceleration and limp in mode problems. Cleaning this throttle body will correct this.
1995 aurora when you press on the gas at idle it goes past 2 rpm and will not come back down someone help please?
Perhaps throttle plate (in throttle body) is sticking Also could be the throttle position sensor or the idle position sensor and could be the throttle cable --if you have used any fuel enhancers it gums up the throttle position sensor and it will stick. Had the same issue with 1996 -its the senors in your transmission-has 2 -need to put on diagnostics for which is causing it and then to replace parts -approximate cost for for part 60.00 cad -labour 1200.00 to 1600.00
How do you fix a high idle in a 95 cavalier when started idels at about 1000-1500 then when driven a block goes down to normal?
Could be a Throttle Position Sensor.
You have a 96 silverado it idles high while in park 1500-2000rpm but in drive or reverse it goes to 1000rpm?
My '95 did the same thing. It was the Throttle position sensor.
Where is the Throttle Position Sensor on a 1999 Honda Passport?
Straight back from the radiator cap, you'll see where the large tube from the air filter enters the throttle body, top front center of the engine. The throttle position sensor is bolted to the right side of the throttle body where this air feed attaches. There's a set of wires plugged into it at the top. The throttle position sensor is a smallish (1 1/4" x 2 1/2"?) plastic component and is attached with two Torx head bolts, size T25. To get at these, you'll need to unclip the plug that goes into the TPS as well as the two other plugs on the same bundle of wires. This comes from the right; the first plug on the line clips onto the air mass sensor (in the tube from the air cleaner), the second goes to the throttle position sensor, and the last one crosses the front of the throttle body and plugs into a sensor on the other side. Unclip all three and bend the wire back out of the way to the right so you can get at the two bolts from the right side. One is on the front side of the TPS, the other is on the bottom.
Does anyone have any idea what the problem might be with my 2005 kia sedona minivan it goes off if I let the accelerator go?
More than likely throttle position sensor
How can you tell if a throttle position sensor goes bad on a 1988 Chevy 2.8 engine?
loping idle. does not maintain idle, sometimes shuts engine off. do an ohm test.
Why would a 1997 Plymouth Breeze and shift perfectly from 1 gear to 2 gear but when it goes from 2 gear to 3 gear it takes it a long time and the motor seems to strain till it shifts?
You may want to check the throttle Position sensor. I had the same thing happen on a 1997 Breeze and eventually it failed to the point that it dumped a code for the Trottle Position Sensor. I changed that and all was fine.
Throttle positioning sensor on a 2004 gmc envoy xuv what will happen if it goes bad?
If the TPS or Throttle Positioning Sensor goes bad on a 2004 GMC Envoy SUV, the car will have a very rough idle. The engine might stall frequently and the cruise control will not function properly. The car will also use much more fuel than is necessary.
