Please feel free to contact us with any questions about your check engine light or P codes. You can use this form to inquire about P codes that you don’t see on the list, if you have further questions about a P code that we have defined, or if you have questions about further diagnosis. Our certified technician will review your email, and get back to you promptly. Normally the response time is 45 minutes or less. If there needs to be in depth research about your inquiry, there may be a longer wait time. If this is the case, we’ll email you back as quickly as possible, to let you know that we’ll need time to do the additional research.
