What is the red lightning fault light of Chrysler 300c instrument?

Chrysler 300C (view transaction price | model details) Instrument red lightning fault light is electronic throttle control indicator light. Electronic throttle is an important control part of automobile engine. It consists of engine, speed sensor, throttle and so on. The electronic throttle control system can accurately control the throttle opening.

Throttle failure will lead to the cylinder is not airtight, there is a phenomenon of mixed gas leakage, the pressure in the cylinder is not enough, and it is very difficult to ignite. Under high voltage, the in-cylinder pressure and the compression temperature of mixed gas can't meet the ignition conditions. In severe cases, the cooler can't start, the combustion is incomplete, the locomotive can't save energy, and it will fart.

According to the common faults, the fault causes are classified, including the program fault of the untrustworthy signal of the throttle control unit, the circuit fault of the throttle control unit and the circuit fault of the throttle drive motor.

Visual inspection: look outside the throttle door to see if there is any damage, whether there is carbon deposit in the throttle, whether the throttle control unit shell and wiring are damaged and ablated, and whether the wiring plug is loose.

For internal inspection, use the tool multimeter. Because the throttle control unit contains the throttle position sensor and the circuit for driving the motor, it is necessary to determine whether there is poor line contact, open circuit or short circuit in the circuit by measuring the voltage and resistance of the wiring plug.
