Is the check engine light in Karvaan often related to catalytic converter issues?

When the check engine light appears, many users are told it’s due to a clogged converter o r sensor error. Are these errors common in Karvaan, and how should they be diagnosed?

Yes. The Check Engine Light CEL can appear due to:

Catalyst efficiency below threshold

Faulty oxygen O2 sensor readings

Exhaust restriction detected by ECU

Using a diagnostic scanner OBD-II can confirm if the code relates to the catalytic converter often P0420 code. These issues are fairly common in the Karvaan, especially with low-grade fuel use.
