What is causing the check engine light to appear frequently in Changan Karvaan despite regular maintenance?

Even after periodic servicing, many Karvaan drivers see the check engine light come on. Are faulty o r overly sensitive sensors to blame for these warning signals?

Reasons include:

Overly sensitive sensors

Faulty MAF, O2, o r TPS sensors

Wiring issues o r bad grounding

Even if regular oil changes are done, electrical errors in the sensor system can trigger the warning light.
