Causes of automobile throttle damage

1. Hard failure: refers to mechanical damage. The resistance part of potentiometer is formed by spraying a layer of carbon film on polyester substrate, which is actually a very low-level preparation process with low wear resistance.

2. Soft fault: refers to dirt, maladjustment, etc. The reason is that the throttle valve is too low most of the time. The air flows through the gap of the throttle at high speed, and the accumulated dust has greater influence on the airflow than the adjustment ability of the throttle.

Extended data:

Throttle maintenance method:

1, which should be dismantled and cleaned up.

2. Correct some misunderstandings of cleaning the throttle.

3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.

Precautions for cleaning throttle valve:

First, apply a little oil on the fixed metal beam ring to avoid slipping teeth during disassembly. Remove the metal wire harness ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative electrode of the battery and turn off the ignition switch.
