Category analysis
Where warranty value can appear
Emissions repairs range from one sensor to a costly catalytic converter. Manufacturer emissions coverage and the cause of failure can matter more than the age of the service contract.
The 2 benchmarks in this category put parts between $362 and $2,139.
Modeled labor ranges from 0.6 to 2.3 hours. At the $148 median metro rate, that is roughly $89 to $340 before parts.
Check federal and state emissions coverage first. Service contracts often distinguish mechanical failure from contamination, theft, impact damage and a converter damaged by an upstream fault.
