Mercury Sable unable to pass Texas state inspection due to multiple error codes and persistent check engine light on Mercury Sable

Some Mercury Sable owners report experiencing difficulties passing the Texas state inspection due to multiple error codes and a persistent check engine light. These issues often stem from the need for proper diagnosis of error codes to identify specific problems affecting the vehicle. Additionally, addressing underlying issues, such as faulty oxygen sensors or oil leaks impacting the catalytic converter, is crucial for meeting inspection requirements. Some owners find that resetting error codes and driving the vehicle for a certain distance may temporarily help in passing the inspection, but this is not a permanent fix if the root causes remain unresolved. Furthermore, those whose vehicles fail the emissions inspection due to the check engine light may be eligible for a waiver under specific conditions in Texas. Lastly, it is essential for owners to ensure that the inspection is conducted in the county where the vehicle is registered, as inspections cannot be performed in a different county.
