Why do you have to step on the accelerator when driving in winter?
You must press the accelerator to start troubleshooting:
(1) Inspection of throttle potentiometer
Measure the voltage between pin 5 and pin 7 of the accelerator control component (stepping on the accelerator pedal or pull rope), which should be between 0.4 and 4.5V. If the voltage is abnormal, repair and replace the accelerator potentiometer, repair related lines and adjust the installation position of the accelerator pull rope. If the voltage is normal, proceed to the next step.
(2) Inspection of idle switch
Measure the resistance of the idle switch. When you just step on the accelerator or pull the rope, the resistance value should be ∞; When releasing the accelerator pedal or the pull rope, the resistance should be less than 1ω. If the resistance value is abnormal, repair or replace the idle switch and related lines; If the resistance value is normal, proceed to the next step.
(3) Inspection of water temperature sensor and air temperature sensor.
Check the engine water temperature sensor and air temperature sensor. Their resistance values should change with the change of temperature, the interval should not exceed 2℃, and decrease with the increase of temperature (NTC). If the water temperature is abnormal, check or replace the sensor and related circuits; If the water temperature is normal, check ignition system. The inspection method is the same as above.
