you replace it
My book says that it means "closed throttle position switch" Ed
Closed throttle position switch
What does code po510 means closed throttle position swith
When the engine is not running, the governor spring typically holds the throttle plate in a closed position. This ensures that no air can enter the engine, preventing any unintentional fuel delivery. The throttle plate remains closed until the engine is cranked and begins to run, at which point the governor can adjust its position based on engine speed and load requirements.
A TPS sends info to the ECM (engine control module) as to the position of the throttle, be it closed, wide open or anywhere in between. The TPS would be found on the throttle body.
The throttle shaft in an engine is held in the idle position primarily by the throttle return spring, which provides the necessary tension to keep it closed when the accelerator pedal is released. Additionally, the idle stop screw may be used to set and maintain a specific idle position by limiting how far the throttle plate can open. In some systems, the engine management system may also play a role in controlling the idle position electronically.
My Haynes repair manual shows : It senses throttle movement and position , then transmits a voltage signal to the PCM . This signal enables the PCM to determine when the throttle is closed , in a cruise position , or wide open . A defective TPS can cause surging , stalling , rough idle and other driveability problems because the PCM thinks the throttle is moving when it is not .
Disconnect the negative battery cableRemove the air intake duct and disconnect the TPS and wide open/closed throttle switch electrical connectorsRemove the two retaining screws and separate the TPS from the throttle body
Throtle position sensors generally have very little adjustment,however,there is a setpoint were you would set a sensor.Disconnect throttle position sensor harness connector. Look at the plug with the lock to the right.The top pin is A the middle is B and the bottom is C Make sure that resistance between terminals b and c changes when opening throttle valve manually. Loosen, but do not remove screws. Adjust TPS B & C to 1000 ohms with throttle closed. Tighten screws
To adjust the throttle position sensor (TPS) on a 1997 Nissan pickup, first, locate the TPS on the throttle body. Use a multimeter to check the voltage output; it should typically range between 0.5 to 0.9 volts at the closed throttle position. If the voltage is outside this range, loosen the TPS mounting screws and carefully rotate the sensor until the correct voltage is achieved, then re-tighten the screws. Finally, recheck the voltage to ensure proper adjustment.
To adjust the throttle position sensor (TPS) on a 305 TBI (Throttle Body Injection), first, locate the TPS on the throttle body. Use a multimeter to measure the voltage output at the sensor's middle pin while slowly opening the throttle plate. The voltage should typically range from about 0.5 to 0.8 volts at closed throttle and increase smoothly to around 4.5 volts at wide open throttle. If necessary, loosen the TPS mounting screws and adjust the sensor position to achieve the correct voltage readings, then retighten the screws.
Yes, if the throttle plate is stuck closed.
