How to Reset the Check Engine Light on a 2001 Toyota Camry

by Justin Cupler

The check engine light in your 2001 Toyota Camry is an indicator that there is some sort of problem with the vehicle. The problem can be engine related, electrical or even transmission related. On occasion, this light is caused by something that is not really a problem at all like a loose fuel cap or bad fuel. Whether it is a problem or not, you must reset the check engine light with an OBD-II scanner once you have solved the cause of the light.


Examine the underside of the driver’s side of the vehicle to locate the OBD-II port. The OBD-II port will be a small electrical connector that is roughly 3 inches wide.


Plug the OBD-II scanner into the OBD port on the vehicle.


Turn the Camry ignition to the run position, but do not start it.


Follow the prompts on the scanner to read the codes.


Select the “Erase Codes” function on the OBD-II scanner.


Unplug the scanner after it has prompted you that the function is completed.


Start the vehicle and allow it to run for a few minutes to ensure that the check engine light has been erased.


  • Always make a note of the diagnostic code before erasing it so you know if the code returns.
  • Never ignore a check engine light; additional damage may be caused by driving with it on.
