A failing TPS can cause the engine to search for an idle or surge. You will notice your RPM gauge fluctuating up and down quickly or hear the engine revving up and down on its own. If not repaired immediately, this can eventually cause the engine to die out.

What happens when you unplug throttle position sensor?

If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration. Correcting the TPS then produced a correct idle, and no code.

How much does it cost to reprogram a throttle body?

When the throttle body fails, the engine won’t be able to remove the right mixture and will start to experience problems. To replace your car’s throttle body, you will pay as little as $370 or as much as $1,500. Labor should be between $70 and $260, and parts should cost you from $110 to $600.

Here are some common symptoms of a bad or failing throttle position sensor to watch for: Car won’t accelerate, lacks power when accelerating, or accelerates itself. Engine won’t idle smoothly, idles too slowly, or stalls. Car accelerates, but won’t exceed a relatively low speed, or shift up.

What should TPS be at idle?

At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. If the TPS has a worn spot, most likely it will be between 0 and 20 percent throttle opening. Try holding the throttle between 0 and 20 percent to see if you get a steady reading.
