Manufacturer summary
Original wording in English
Some vehicles may experience an engine that runs rough and the check engine light on with DTCs P0201 and P0204 or P0202 and P0203. NOTE: Engine misfire related DTCs (P0301, P0302, P0303, P0304) are usually stored at the same time. P0201:00 : Fuel injector circuit/open cylinder No.1 P0202:00 : Fuel injector circuit/open cylinder No.2 P0203:00 : Fuel injector circuit/open cylinder No.3 P0204:00 : Fuel injector circuit/open cylinder No.4 This concern may be caused by an internal failure of the PCM (DENSO produced only). To correct the concern, the PCM internal failure has been eliminated.
