How does the throttle position sensor work on a jeep?
This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Powertrain Control Module ( PCM ). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the PCM.
What does the p0123 code on the throttle position sensor mean?
What Does the P0123 Code Mean? The P0123 code indicates a problem with the throttle/pedal position sensor. When the engine control module (ECM) detects that the throttle position sensor’s output voltage rating is exceeding the manufacturer specification, it generates the P0123 trouble code.
What is the trouble code for the throttle position sensor?
When the engine control module (ECM) detects that the throttle position sensor ’s output voltage rating is exceeding the manufacturer specification, it generates the P0123 trouble code.
How much does it cost to diagnose p0123 Jeep code?
The cost of diagnosing the P0123 JEEP code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0123 JEEP code detected? The Throttle Position Sensor ( TPS) responds to the accelerator pedal movement.
How to test the throttle position sensor on a jeep?
CASE 1: The multimeter registered a smooth increase or decrease in voltage with no gaps. This test result tells you that the throttle position sensor (TPS) on your 4.0L equipped Jeep Grand Cherokee (Cherokee, Wrangler) passed with flying colors. This test result also confirms that the TP sensor is getting both power (5 Volts) and Ground.

What’s the TPS code for a Jeep Wrangler?
P0123: TP Sensor Voltage High. Your Jeep Grand Cherokee (Cherokee, Wrangler) fails the state mandated emissions test. Bad gas mileage. Hard start and/or extended cranking time (after shut off). Black smoke coming out of the tailpipe. Hesitation when accelerating your Jeep down the road.
How does the p0123 throttle position sensor work?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is higher than the normal upper limit, P0123 will set.
