How to Troubleshoot 2000 Camry Overheating ECU

Toyota is the world's largest automobile manufacturer.

The ECU (engine control unit) is vital equipment that controls the amount of fuel, ignition timing, air/fuel mixture, idle speeds, valve timing and other essential engine functions. The ECU is often altered for performance or fuel saving. Altering the ECU's setting requires the use of an ECU control module. The ECU in the 2000 Toyota Camry is located under the driver's seat. An overheating ECU should be replaced immediately since it is definitely malfunctioning.

Things You'll Need

• Replacement ECU
• Screw driver
• ECU control module

Instructions

1. Disconnect the car's battery. Remove the positive terminal from the battery.

2. Locate the ECU for the 2000 Toyota Camry. It is located under the driver's seat toward the back center of the vehicle under the carpet. It is a silver box about the size of a large hand.

3. Unscrew the ECU from its mount in the car.

4. Disconnect the wire clips from the ECU. Remove the ECU from the vehicle. An overheating ECU is a major problem, which means something is seriously wrong with the unit.

5. Connect the wire clips to the new replacement ECU. Screw the ECU into the location of the old one. Cover it with the carpet. Reattach the battery and start the car.
