Perodua Ativa Check Engine Light Malaysia
Perodua PID diagnostic tool required for full Ativa codes. Common: turbo boost pressure codes, ASA 3.0 camera fault (after windscreen replacement), O2 sensor, or EVAP system.

Ativa Check Engine Light
- Turbo-specific codes: P0234 (overboost), P0299 (underboost), wastegate fault — scan to identify
- Common non-turbo causes: O2 sensor, MAF sensor, EVAP system, loose fuel cap
- Do not clear the code without fixing the root cause — CEL will return
