In most cases, the P-0137 error code is related to the oxygen sensors on the vehicle. There are typically two to four oxygen sensors on the four cylinder Toyota motor, so a more detailed diagnostic scan should indicate which one is faulty. It might also be the wiring harnesses attached to the oxygen sensors that are damaged. Contact one of our local mechanical professionals to complete this scan for you or to fix the issue you’re experiencing. If it turns out that a replacement is necessary, certified mechanics are available to replace the oxygen sensors for you.
