Services Performed
- Performed testing on the check engine light. There is a code P0420 catalyst efficiency below threshold. Monitered vehicle data and at an idle the catalytic converter is working good however under a load the catalytic converter is not very efficient. Verified there is good oxygen sensor signals and verified there is good fuel trim numbers. The catalytic converter is weak and will need to be replaced. The cruise control light is due to the check engine light being on
