What happens to p0123 when the throttle is closed?
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.
When to replace throttle body on Jeep Compass?
Multiple issues with throttle body resulting in a loss of power and control of vehicle. Back in 2017, I had an issue with the car jerking, cutting out, and losing power. Took car to a Jeep dealership and throttle body had to be replaced. Again during the summer of 2020, vehicle started losing ability to consistently accelerate.
Why does my Wrangler have a p0123 code?
Im working on a friends 1999 wrangler with the 4.0 6 cylinder. I read the resistance of the tps through the operating range and the voltage through the range and it seems to be in spec. The TPS show 15.7% duty at no throttle. Im thinking that the p0123 code is due to a short in the harness/connecter…
Is there a problem with the throttle control on my Jeep?
The Jeep continues to run perfectly, this is just an annoyance. Well, I think I may have finally fixed the electronic throttle control light problem on my Jeep. This has been a problem for the past several months. The ETC light would come on several times a week.
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.
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 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 happens to the TPS when the throttle is closed?
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. other symptoms may also be present
How does the TPS work on a Nissan p0120?
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.
