What the hell is wrong with Cruze code84?

This is a throttle position sensor fault. 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 lead to engine jitter and unstable idle speed. When the car is driving, the engine is easy to stall, and it is difficult to drive or start. Replace the throttle position sensor and troubleshoot. The fault of the throttle sensor will affect the idle speed control function of the engine computer, resulting in abnormal idle speed (such as too high or too low idle speed, unstable idle speed and easy idle speed) or abnormal engine acceleration (such as engine jitter during acceleration and delayed acceleration response). It may also cause the engine to shake intermittently 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 appear on the dashboard, it means that the car may be in a dangerous situation. The tachometer is usually set on the instrument panel. 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 converts the signal into a displayable rotational 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. Million car purchase subsidy
