Why do you need a throttle body on a jeep?
A throttle body controls the airflow in to your Jeep’s engine. As you depress the accelerator pedal, the butterfly valve opens to allow more air to enter the engine. Upgrading the original throttle body to a larger one can allow for more horse power to be made.
How to diagnose a jeep throttle position sensor?
Locate the connector that goes from the ECM (engine control module) to the TPS and disconnect it from the TPS. There are usually three prongs; the center prong is normally the negative connector. Take the volt meter and connect the negative side (usually the black wire) to the ground terminal on the battery.
What is the code for the throttle control on a jeep?
P0299 is the only code that came up. Turbo under boost. There was a loose hose clamp on the turbo outlet pipe and there was some sludge that spewed out a bit. I tightened it and disconnected the battery for a half hour. Code popped up again as soon as I started it again.
How does the TPS work on a jeep?
The TPS is used to monitor the position of the throttle butterfly valve. When the car accelerates, the butterfly opens to allow air into the intake manifold. There are a few signs that could signal that the throttle position sensor is failing. Turn on the ignition to the “On” position, but do not start the car.
