what could cause my Honda CR-V to lose power while driving

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before starting work.

2. Air Filter Replacement

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and inspect the housing for debris.
• Install a new air filter, ensuring it fits snugly.
• Reattach the air filter housing cover and secure it properly.

3. Fuel System Inspection

• Locate the fuel pressure test port on the fuel rail.
• Connect the fuel pressure gauge to the test port.
• Turn the ignition to the "ON" position (not start) and record the pressure reading.
• If pressure is below specifications, check the fuel pump and filter for replacement.

4. Throttle Position Sensor (TPS) Testing

• Locate the TPS on the throttle body.
• Disconnect the electrical connector.
• Use a multimeter to test resistance across the terminals while moving the throttle plate.
• Replace the TPS if readings are inconsistent or out of specification.

5. Ignition Component Replacement

• Remove the engine cover if necessary to access ignition components.
• Replace spark plugs using a spark plug socket, ensuring correct gap settings.
• Inspect and replace ignition wires and coils as needed based on visual inspection.
