How to measure the throttle line 6 of old Jetta

Connect the diagnostic instrument to the diagnostic base, and then start the engine. The normal opening value of throttle position sensor 1 is 3%-93%, throttle position sensor 2 is 3%-97%, throttle position sensor 3 is 12%-97%, and 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.

Precautions for throttle valve

When cleaning the throttle valve, the throttle valve must be removed for cleaning, so that the cleaning can be carried out, and the electric part of the throttle valve will not be sprayed because the cleaning liquid is sprayed in only one direction, which will seriously damage the throttle valve.

When cleaning the throttle, spray the throttle cleaning solution to the position with more carbon deposits, wait for 5- 10 minutes, and the carbon deposits will be dissolved by the cleaning solution. At this time, brush with a clean brush and wipe with a clean towel. Before installation, you must wait until the throttle cleaning solution is completely dry before installation.
