“My truck feels sluggish, the engine RPM is always low, I don’t know what’s wrong.” This is the lament of a friend of mine, a long-time truck driver in Long Bien, Hanoi. Low engine RPM is a common problem in trucks, affecting performance and lifespan. So, what are the causes and how to fix this problem? Let’s explore in detail with XE TẢI HÀ NỘI.

1. Causes and Solutions for Low Engine RPM

Low engine RPM can stem from various causes. Here are 5 of the most common:

1.1. Clogged Air Filter

The air filter prevents dust and debris from entering the engine. When the air filter is clogged, the airflow to the engine is reduced, leading to low engine RPM.

Solution: Regularly inspect and clean the air filter. If it’s too dirty or damaged, replace it at a reputable truck dealer like XE TẢI HÀ NỘI.

1.2. Faulty Throttle Position Sensor (TPS)

The TPS sends signals about the throttle opening angle to the Engine Control Unit (ECU). A malfunctioning TPS prevents the ECU from accurately adjusting the fuel injection, causing low engine RPM.

Solution: Inspect and clean the TPS. If it’s damaged, replace it.

1.3. Ignition System Failure

The ignition system generates the spark to ignite the fuel-air mixture in the engine. Issues like weak spark plugs or damaged high-voltage wires hinder efficient combustion, resulting in low engine RPM.

Solution: Inspect and replace any faulty components within the ignition system.

1.4. Low Fuel Pressure

Low fuel pressure can be due to a weak fuel pump, a clogged fuel filter, or a leak in the fuel line. This restricts fuel supply to the engine, causing low engine RPM.

Solution: Inspect and address any issues related to the fuel pump, fuel filter, and fuel lines.

1.5. Faulty Oxygen Sensor

The oxygen (O2) sensor measures the oxygen level in the exhaust gases, enabling the ECU to adjust the fuel/air mixture. A faulty O2 sensor sends incorrect information to the ECU, leading to improper fuel delivery and low engine RPM.

Solution: Inspect and replace the oxygen sensor if necessary.
