Has your engine check light ever turned on due to a faulty oxygen sensor o r other engine-related sensors?

Oxygen and MAF sensors can trigger the check engine light when they malfunction. Have you had to get any sensors replaced o r cleaned due to such errors?

Yes, a faulty oxygen sensor o r MAF sensor Mass Air Flow often triggered the check engine light in Oshan X7. Many owners had to clean o r replace these sensors. The check light usually turned off after a diagnostic scan and cleaning. Some faced this issue around 20,000–30,000 km of usage.
