my Toyota Camry Eighth Generation (2018-present) has a warning light on and won't accelerate

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies.
• Disconnect the vehicle battery to ensure safety while working on electrical components.
• Allow the engine to cool down before starting any repairs.

2. Addressing Error Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Record any trouble codes and refer to manufacturer specifications for diagnostic direction.
• Clear the codes and verify if they return after a test drive.

3. Cleaning the Throttle Body

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a soft brush to clean the throttle body and remove carbon deposits.
• Reassemble the duct and ensure all clamps are tight.

4. Checking Accelerator Pedal Position Sensor

• Locate the accelerator pedal position sensor (usually mounted on the pedal assembly).
• Disconnect the electrical connector and check for continuity using a multimeter.
• Replace the sensor if no continuity is detected or if readings are outside manufacturer specifications.

5. Inspecting Fuel System

• Connect the fuel pressure gauge to the fuel rail.
• Start the engine and monitor the fuel pressure; it should meet manufacturer specifications.
• If the pressure is low, check the fuel pump and filter for proper operation, replacing components as necessary.
