why does my Toyota Camry Seventh Generation (2012-2017) go into limp mode

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.

2. Address Fault Codes

• Sub-steps:
  1. Connect the OBD-II scanner and retrieve error codes.
  2. Research the codes to identify possible faults (e.g., P0300 for misfire, P0171 for lean condition).
  3. Clear the codes and perform a test drive to see if they return.

3. Throttle Body Cleaning

• Sub-steps:
  1. Remove the air intake duct connected to the throttle body.
  2. Clean the throttle body using throttle body cleaner and a soft cloth.
  3. Reinstall the air intake duct and reconnect any sensors.

4. Transmission Fluid Check

• Sub-steps:
  1. Locate the transmission dipstick and check fluid level with the engine running and in park.
  2. If low, add the recommended transmission fluid (Dexron VI).
  3. If fluid is dark and burnt, consider a transmission fluid change.

5. Inspect Electrical Connections

• Sub-steps:
  1. Visually inspect all wiring harnesses connected to the ECU and throttle body for wear or corrosion.
  2. Use a multimeter to check for continuity and correct voltage readings.
  3. Repair or replace any damaged wiring or connectors.
