Has your Oshan X7 shown a check engine light that was later diagnosed as a catalytic converter fault?

The “Check Engine” light can be triggered by sensor readings from the exhaust system. Did your scanner o r mechanic confirm the issue was with the catalytic converter?

Yes, in a few cases, the Check Engine Light CEL came on and OBD-II scans revealed error codes like P0420, which indicate catalyst system efficiency below threshold. These errors were often linked to a faulty converter o r oxygen sensor.
