Hi there. Welcome to our site!


I’m a retired master technician and tech instructor with over 30 years experience. However, if you’re thinking on working on the vehicle yourself, all my knowledge and resources won’t help if you…

… don’t have tools or the skills to use them

… don’t know there will probably be some special tools and equipment needed for a proper diagnosis

… don’t realize it may take a few back and forth replies to solve the issue

… don’t understand that I will need you to provide specific information

Is the speedometer displaying the correct vehicle speed?

  • If it's not, the problem might be the vehicle speed sensor itself, the connector or the harness.
  • If it is, the problem might be a bad PCM; more testing using a voltmeter is required

Please let me know if you have any other questions.

Best Regards.
