Cruze dashboard shows what is the fault of code84?

The throttle position sensor is faulty. It is recommended to go to the 4s shop to clean the throttle or replace the throttle.

If the throttle position sensor is damaged, it will cause engine jitter and unstable idle speed, and the engine will easily turn off when the car is driving, making it difficult to drive or start. Replace the throttle position sensor with a new one and correct the fault.

The failure of the throttle sensor will affect the idling control function of the engine computer, resulting in abnormal idling operation of the engine (such as too high or too low idling speed, unstable idling speed and easy flameout) or abnormal acceleration of the engine (such as engine jitter during acceleration and slow acceleration response), and may also lead to intermittent jitter of the engine during operation.

Precautions:

Electronic security systems signs visible on the dashboard include body stability system, traction control system and tire pressure detection. If the icons of these three functions all appear on the dashboard, it means that the car may be in a more dangerous situation.

The tachometer is generally set on the dashboard. Placed symmetrically with the speedometer. The tachometer works according to the magnetic principle and receives the pulse signal generated when the primary current of the ignition coil is interrupted. And convert that signal into a displayable speed value. The faster the engine speed, the more pulses generated by the ignition coil, and the greater the speed value displayed on the instrument.
