What happens if you unplug a 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.
How do you remove the throttle body from a car?
Remove the hardware that mounts the throttle body to the intake manifold. This can include a number of bolts, nuts, clamps, or screws of different types. Step 6: Separate the throttle body from the intake manifold. With all of the throttle body mounting hardware removed, gently pull the throttle body away from the intake manifold.
What to do if your throttle is not working?
If you feel the throttle body has no issues and you do not see any faults in the throttle body, but still you are getting the throttle failure signs, then you can try with resetting the throttle part. The throttle system works with the electrical connection of the engine, and it may get incorrect trouble codes in the electrical functions.
How to repair a wiring harness and throttle position sensor?
Plug in the wiring harness connector if you are not going to change it. Cut the wires on the pigtail about 1 inch away from where they enter the main wiring harness. Strip about 1/2 inch of the insulation off the wires at the main wiring harness connector. Insert each one of the bare wires into a separate butt connector.
How is the throttle body connected to the PCM?
The throttle body is linked with a throttle body position sensor which collects information regarding the amount of air entering the intake. The sensor then transfers this information to the PCM which decides how much fuel should be mixed for an effective combustion process.

Is the throttle body dependent on other parts?
This is carried out electronically in electronic fuel injection engine systems. In most vehicles, there is only one throttle body, with a rare exception of special, larger vehicles. The function of the throttle body is also dependent on other parts, such as the air filter.
What causes the throttle body to get stuck?
Even if you have an air filter on your car, dirt and soot come from the turbocharger, EGR valve, and the crankcase ventilation and get stuck on the throttle body valve. After a whole, it will cover the valve so much that the RPM will be affected.
