What does the TP sensor do on a Jeep Cherokee?
The TP sensor provides the PCM with throttle plate angle info. This, in layman’s terms means that it tells the computer how much you’re stepping on (or off) the accelerator. The throttle angle info the throttle position sensor (TPS) provides is key to engine performance. So, when this bad boy fails, your Jeep is gonna’ resent it.
What happens when the TPS on a Jeep Grand Cherokee fails?
When the throttle position sensor (TPS) fails, you’ll see one or more of the following symptoms: Check engine light (CEL) shining nice and bright. 24: TP Sensor Voltage Low. 24: TP Sensor Voltage High. Your Jeep Grand Cherokee fails the state mandated emissions test.

Can you change the TPS on a Jeep ZJ?
While changing the TPS did not solve my transmission problem, without a doubt the engine seems to run smoother with the new part. I love the price! Really affordable. I bought for my 95 jeep Cherokee Zj and it completely eliminated the spuddering it restored power and no more hesitation
How to know if your throttle position sensor is too high?
Check the voltage at the TPS (refer to a service manual for your vehicle for this specific information). If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.
When does a TPS sensor indicate a problem?
If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc. Other TPS sensor and circuit related DTCs: P0120, P0121, P0122, P0123, P0124
How to test the TPS code on a jeep?
Connect the black multimeter test lead on the battery negative (-) terminal. Turn the key to the ON position but don’t start the engine (this will power up the TP sensor). Your multimeter should report 0.4 to 0.9 Volts DC. If your multimeter doesn’t, don’t worry about it just yet, continue with the other steps.
When the throttle position sensor (TPS) fails, you’ll see one or more of the following symptoms: Check engine light (CEL) shining nice and bright. 24: TP Sensor Voltage Low. 24: TP Sensor Voltage High. Your Jeep Grand Cherokee fails the state mandated emissions test.
What happens when the throttle position sensor ( TPS ) fails?
When the throttle position sensor (TPS) fails, you’ll see one or more of the following symptoms: Check engine light (CEL) shining nice and bright. Diagnostic trouble codes (DTC) stored in the PCM’s memory: 24: TP Sensor Voltage Low. 24: TP Sensor Voltage High. Your Jeep Grand Cherokee fails the state mandated emissions test. Bad gas mileage.
What do you need to know about TPS sensor?
TPS TEST 1: Testing The TPS Voltage Signal. This first TP sensor test involves tapping into the sensor’s middle wire, with your multimeter, and manually opening and closing the throttle plate to see if the multimeter registers the changes in the voltage output (of the sensor). If the throttle position sensor is good,…
What are the symptoms of a TPS sensor failure?
The throttle angle info the throttle position sensor (TPS) provides is key to engine performance. So, when this bad boy fails, your Jeep is gonna’ resent it. You’ll see one or more of the following symptoms: Check engine light (CEL) shining nice and bright. P0121: TP Sensor Voltage Does Not Agree with MAP sensor.

Is there check engine light on Jeep Grand Cherokee 4.7?
I recently bought a 2005 jeep grand Cherokee 4.7, and notice check engine light and traction control light came on. Autozone has a great service where you can get a print out of what the specific problem is and how it might effect other parts.
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.
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.
How to check engine light codes on Jeep Cherokee?
Jeep Check Engine Light Codes 1 Connect scan tool to the 16-pin data link connector (DLC) located near the steering column. The connector may have a removable cover. 2 Turn the ignition on. 3 Follow scan tool manufacturer’s operating instructions to access the Diagnostic Trouble Codes (DTC’s).
How to reset your Jeep engine control module?
