How to solve the high voltage of Accord throttle position sensor

Honda Accord (view transaction price | vehicle details) The high voltage of the throttle position sensor is caused by the damage of the throttle position sensor or poor line contact. It is recommended to replace the sensor with a new one and check the wiring problem. The throttle position sensor will output a signal voltage of 0.5-4.5V according to different working conditions and opening.

Automobile throttle position sensor, also known as throttle opening sensor or throttle switch, is a device used to detect the engine state. Its main function is to detect whether the engine is in idle or load condition, acceleration or deceleration condition. It is essentially a variable resistor and several switches installed on the throttle body.

The solution to the high voltage of Accord throttle position sensor is as follows:

1, check the air intake system. Clean throttle valve, check air chamber, etc. , and check whether the vacuum tube falls off or leaks;

2. Check the electrical system. Check the high voltage line, spark plug, ignition coil, ignition timing, etc.

3. Check the oil supply system. Check the electronic oil pump, nozzle, acceleration pump, etc.

4. The air intake of the engine is very small, which leads to the rich mixture. The engine is not easy to start because of the large gap between the concentration of mixed gas and the air-fuel ratio required for starting. Check the air intake system, the air intake pipe for no air leakage, whether all vacuum tubes are connected properly, the air grille and the throttle valve for no sticking. Check the idle motor, sometimes the idle motor will get stuck. Moreover, the higher the temperature, the higher the frequency of idling motor jamming;

5. Check whether the coolant temperature sensor is short-circuited or open-circuited, and the other is to check whether the EGR solenoid valve and circuit are short-circuited or open-circuited.
