Daughter's 02 Civic CEL came on three times in 10 days. On each occurrence, the car immediately went to idle, but after being turned off and restarted, the car ran fine with no CEL. After the third time, she took it to an independent garage. The mechanic told her the code indicated an ECM (ECU, computer) problem and she needed to take it to a Nissan dealer. Her appointment with Nissan is tomorrow.
The question is: When the codes were read, would they have been reset? Or will the fault code still be there? No need for her to pay $85 to Nissan if there are no codes to read...
Thanks.
