CAT - O2 SENSOR QUESTION 200

posted by  someone claiming to be Mike on  Fri Sep 6 03:58 CST 2024 [RELATED]

93 Volvo 240 - CAT has flex flange - pipes in and out are rusted so needs replacing.
Is it simply a matter of replacing the direct fit unit and then unplugging and replugging the sensor on the CAT?

Any issues to be aware of - check engine light etc.

No lights or issues at present - old units pipes are just rusted out and beyond repair but CAT unit itself is intact and getting no lights.

Thanks

    I can't answer your model specific question but a shop that replaces cats should have the means to look up any associated procedures. If the cat is good, repairing/replacing some pipes should not be a problem. Consider the cost of a new OEM cat. If necessary, a generic cat (must meet your state's approval) might be a better deal. Same applies to an O2 sensor.

      Thanks. Just wondering if you just unscrew the old sensor and screw it into the new one.
