OBD II trouble code P TP Sensor Circuit Low Voltage is telling you that your Honda's fuel injection computer is seeing a low voltage output from the throttle position sensor TPS that doesn't correspond to the actual throttle plate opening or current engine operating conditions.

Testing the TPS can easily be done with a multimeter and in this tutorial, I'm gonna' show you how in a step-by-step way.

Throttle plate position, without saying, has a direct impact on the amount of fuel your Honda's fuel injection computer injects into the engine's cylinders. When the throttle closes, and lessens the amount of air flow into the engine, the less fuel the PCM needs to inject. So when the PCM gets the wrong throttle opening info from the throttle position sensor TPSeither because the TP sensor has failed or there's a problem in the sensor's wires, it can no longer control fuel injection to maximize performance and a host of other things.

Although I'm not going to go into minute technical detail about the inner workings of the sensor, the following brief description of how the throttle position sensor TPS works will help make sense of what exactly we're gonna' be testing for in the next pages of this tutorial:. As the throttle plate starts to open as you accelerate the enginethis voltage starts to increase.

At wide open throttle, the TP sensor will output about 4. Since the angle of the throttle plate is crucial for proper fuel injection and a host of other things, when your Honda's PCM sees the wrong throttle angle information, then it's not gonna' to be able to keep your Honda's engine running smoothly.

In this tutorial, I'll help you troubleshoot all three of the above. With this basic info under our belts, let's turn the page and get testing! Some people dream of things that never were and ask, Why not? Page 1 Page 2 Page 3 Page 4.

P Honda Description The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the Engine Control Module ECM.

The ECM determines the vehicle speed based on the frequency of these pulse signals.

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

The oxygen 02 sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.
