What is the detection method of 6-plug electronic throttle?

There are many methods to detect the 6-plug electronic throttle, including reading data directly, detecting the voltage of the throttle position sensor, detecting the power supply voltage and detecting the resistance.

1. Direct data reading: connect the diagnostic instrument to the diagnostic seat, and then start the engine. The normal opening of throttle position sensor 1 is 3%-93%, that of throttle position sensor 2 is 97%-3%, that of throttle position sensor 3 is 12%-97%, and that of throttle position sensor 4 is 4%-49%. If the measured value is less than the above range, there is something wrong with the throttle. At this time, inspection and maintenance should be carried out to avoid the normal use of the car due to the damage of the throttle.

2. Detect the voltage of the throttle position sensor: When the throttle valve is fully opened, its voltage is about 5v. When the throttle valve is closed, its voltage is about 0.5v

3. Test the power supply voltage: unplug the throttle position sensor and start the engine. The voltage between vcc and throttle is usually between 4.5 and 5.5 volts.

4. Detection resistance: The resistance between vcc and idle contact is generally 1.5-2.6 ohms. The resistance between vcc and vih is generally 0.75- 1.3 ohm. (Photo/Text/Photo: Dong Peng) @20 19
