How is throttle position sensor on Jeep Wrangler YJ?
Jeep Wrangler YJ – Testing the Throttle Position Sensor. Remember, even though mine is a little high on the low side voltage. The main thing you need to check for is you are getting voltage at all. The WOT voltage is below 5 volts. Idle voltage just above .2 volts. Also, as you open the throttle slowly you gain voltage smoothly.
What do you need to know about the throttle position sensor?
The throttle position sensor (TPS) is used in fuel-injected and carbureted engines. 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.
What should TP reading be on Jeep Wrangler?
Divide the output voltage reading by the input voltage reading. The result should be between .825 and .835 (.830 is optimum). If yours is not in this range, adjust the TPS by loosening the Torx head retaining screws and turning the TPS slightly then repeat the test until it falls into this range.
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.
Where is the throttle position sensor on a Jeep Wrangler?
Locate the connector on the back of the throttle position sensor but do not unplug it. Locate the markings on the connector that indicate the positions. Each is marked with a letter starting with A and running through D. Insert the black test lead from your voltmeter into the back of terminal D, being careful not to damage the wire or terminal.
How can you tell if your throttle position sensor is bad?
The most common symptom is your check engine light. This indicator is a vague symptom, as it could also point to a variety of issues, but you can expect to see it if there’s any issue with your throttle position sensor. Next, any unusual changes in your acceleration could be linked to this sensor.
Divide the output voltage reading by the input voltage reading. The result should be between .825 and .835 (.830 is optimum). If yours is not in this range, adjust the TPS by loosening the Torx head retaining screws and turning the TPS slightly then repeat the test until it falls into this range.
What causes a bad MAF sensor on a Jeep Wrangler?
A bad mass airflow sensor can leave your Jeep Wrangler’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold.
