my Honda CR-V Fifth Generation (2017-2022) revs high but won't accelerate

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. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, wrench set, fluid catch pan.
• Inspect the transmission fluid dipstick (if applicable) to check the fluid level.
• If the fluid is low or burnt, drain the old fluid using a fluid catch pan and replace it with the manufacturer-recommended transmission fluid.
  • Fluid Type: Honda ATF DW-1 or equivalent.
• Reconnect the battery and start the engine; allow it to warm up before checking the fluid level again.

3. Inspect and Clean Throttle Body

• Tools Required: Throttle body cleaner, screwdriver set, microfiber cloth.
• Remove the air intake duct connected to the throttle body using a screwdriver.
• Clean the throttle body using throttle body cleaner and a microfiber cloth to remove any carbon buildup.
• Reassemble the intake duct securely.

4. Test and Replace Accelerator Pedal Position Sensor (if needed)

• Tools Required: Multimeter, screwdriver set.
• Disconnect the electrical connector from the accelerator pedal position sensor.
• Use a multimeter to test the sensor's voltage output while slowly pressing the accelerator pedal. Refer to the vehicle’s service manual for specific voltage ranges.
• If the sensor is faulty, replace it with a new one and reconnect the electrical connector.

5. Inspect Transmission Components

• Tools Required: Creeper, flashlight, socket set.
• Raise the vehicle securely using jack stands.
• Visually inspect the transmission for any signs of leakage or damage.
• Check for damaged drive shafts or CV joints that may affect acceleration.
