Q: How clean the throttle body cleaning...and reset the M.I.L an

Spray on solvents are used to clean the throttle body. These are widely available at auto parts stores and many household goods retailers. However, prior to cleaning the throttle body, the reason that the check engine light has come on should be determined. To do that, the trouble code(s) should be downloaded from the vehicle computer and the systems, parts, components, or sensors referred to in the code(s) should be properly tested and diagnosed. Once the cause of the malfunction, that has caused the warning light to illuminate, is pinpointed then, and only then, will the repair strategy be clear. As far as resetting the light, once the actual fault is cleared, the light will often reset on its own. If not, the code scanner that is used to download codes, can also erase codes and re-set the light. If you desire a diagnostic to pinpoint the actual fault, the recommended service in your circumstances is a check engine light diagnostic.
