What is the reason why the electronic throttle control indicator light is on?

The electronic throttle control indicator light of Pacific Auto Network is on, which may be due to the problem of carbon deposition on the electronic throttle, reminding the owner to clean the throttle in time.

What does EPC indicator light mean?

The EPC indicator light is always on, indicating that the engine and electronic system are out of order. If the light is always on or flashing after ignition or during driving, it means that the management system has detected the fault of the engine or electronic system. Please contact the service station immediately. Of course, if the engine shuts down due to improper operation, this indicator light will also light up, telling you that everything is normal after the ignition is restarted. 95% of the reason why EPC lights are often turned on is because the electronic throttle is dirty.

When the car EPC light is on, there are the following situations:

1, air intake system failure, such as leakage or blockage;

2. The throttle body is dirty and has too much carbon deposit;

3. The fuel selection is not up to standard;

4. Abnormal cylinder pressure and poor working conditions;

5, occasional failure, a false alarm;

6, valve failure, stuck or carbon deposition, etc. ;

7.ECU failure.

Solution:

1, air intake system troubleshooting, fuel selection criteria, cleaning throttle body, etc.

2. Remove carbon deposits in related parts.

3. Rewrite the relevant data of ECU (this is a situation that cannot be ruled out after solving other faults).

4. The possibility of other faults is not ruled out, and the actual vehicle test results shall prevail before maintenance.
