WARNING: This page is about a different variant/trim than selected.
- P1200: 00 is a DTC for indicating that deposit accumulation is progressing in the fuel system. If deposit accumulation further progresses, DTC P0171: 00 may be stored and the check engine light may turn on.
- If the PCM predicts that DTC P0171: 00 will be stored in the future based on the history of the fuel correction amount while driving for the last 2, 400 km {1, 491 miles}, a DTC is stored.
- Deposit is removed by adding deposit cleaner at the timing when DTC P1200: 00 was stored.
