Why does the Chery E5's fuel gauge move but the speed doesn't increase?
2 Answers
The reasons why the Chery E5's fuel gauge moves but the speed doesn't increase are as follows: Sensor failure: The car's brake sensor failure causes the onboard computer to limit the engine speed. Timely inspection of the car's brake sensor at a 4S shop or repair shop can solve the problem of the computer limiting the engine speed. Throttle pedal issue: Problems with the car's throttle pedal can cause unstable voltage when the throttle is pressed, leading to the speed not increasing. The throttle pedal pulls a cable that moves the throttle body, which has a position sensor. The control unit uses the throttle position sensor signal to determine the throttle opening and then calculates the corresponding signal voltage. Inspect the car's throttle pedal and repair or replace it if necessary.
I've been driving for over 20 years and have driven many Chery E5 models, encountering slow acceleration issues multiple times. The fuel gauge shows sufficient fuel, but the car struggles to gain speed. The most common causes are ignition system problems, such as worn spark plugs or faulty ignition coils, where sparks fail to ignite the fuel, resulting in weak engine performance. Another possibility is fuel system blockage, where impurities clog the fuel pump or fuel lines, causing insufficient fuel pressure and poor acceleration. A clogged catalytic converter in the exhaust system can also reduce exhaust efficiency, making the car sluggish. Additionally, for manual transmission Chery E5 models, excessive clutch wear might be the culprit. It's advisable to first check if the air filter is dirty—replacing it costs just a few dozen yuan. If the issue persists, visit a professional repair shop promptly to avoid long-term engine damage. Regular maintenance and avoiding aggressive throttle starts can help prevent these problems.
