What to Do If Fuel Consumption Increases After Cleaning the Throttle Body?
1 Answers
After cleaning the throttle body, fuel consumption may increase significantly in the short term. This is because the original carbon deposits on the throttle body are removed, leading to increased air intake and consequently higher fuel consumption. The situation can stabilize over time or be resolved by performing an ECU reset, after which fuel consumption will return to normal. More details about the throttle body are as follows: 1. Introduction One: The carbon deposits in electronic throttle bodies should be cleaned every 10,000 kilometers or when the fault indicator light comes on. Cleaning the carbon deposits can affect the vehicle's performance. Taking fuel-injected vehicles as an example, after cleaning the carbon deposits in the fuel system and throttle body, the vehicle may consume more fuel initially. The onboard computer requires a learning process to adapt to the engine's operating conditions post-cleaning, which typically takes about 1,000 kilometers. 2. Introduction Two: Generally, fuel-injected vehicles require an ECU reset after cleaning the throttle body. If this step is skipped, it may result in a significant increase in fuel consumption. The simplest reset method is to disconnect the battery for more than 30 seconds, preferably for one minute, before reconnecting it and driving the vehicle. 3. Introduction Three: Some vehicle models require a reset through the onboard OBD interface connected to a diagnostic computer. In such cases, the reset can only be performed at a 4S dealership or a repair shop equipped with a diagnostic computer.
