why does my Ram 1500 DT (2019-Present) have poor acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Address Fault Codes

• Use the OBD-II scanner to clear any error codes after repairs.
• Investigate and repair any specific fault codes found during scanning.

3. Inspect and Replace Air Filter

• Locate the air filter housing and remove the cover.
• Take out the existing air filter and visually inspect for dirt or damage.
• Replace with a new air filter if necessary, ensuring a proper fit.

4. Fuel System Check

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "ON" position without starting the engine and note the pressure reading.
• If pressure is below specifications, inspect and replace the fuel pump or filter as needed.

5. Spark Plug Inspection and Replacement

• Remove spark plug wires carefully with a spark plug puller.
• Use a spark plug socket to remove the spark plugs.
• Inspect for wear or carbon buildup; replace all spark plugs if necessary with OEM parts.

6. Throttle Position Sensor (TPS) Testing

• Locate the TPS on the throttle body.
• Disconnect the electrical connector and use a multimeter to measure voltage at the sensor.
• If readings are out of specification, replace the TPS.

7. Exhaust System Inspection

• Inspect the exhaust system, focusing on the catalytic converter for signs of blockage.
• If clogged, replace the catalytic converter according to manufacturer specifications.
