Of course I have never had a OBD2 car. :facepalm :Idiots you can not “delete” a code from your ECU. EVER!.. now with certain tuning software you can turn off a code from activating a check engine light but that wont “delete” the code off the system. The code will still come up if you use a scan tool on the cars computer but depending on what codes you turn off you can still pass inspection ex. i have turned off my rear o2 sensor code from setting a check engine light. b/c i have an 06 i can only have 1 readiness monitor not set when i go to get my car inspected. so turning off my rear o2 sensors means it’s my only pass to get by with an inspection. i’ve inspected my car twice with the code turned off and passed inspection with flying colors. i know most of this is going to go right over your head so do some google searches on readiness monitors new york state inspection obd-II codes --- _[View the full topic](https://forums.speedlife.net/t/is-there-a-way-to-physically-delete-codes-from-your-ecu/248450)._
