Official summary
In certain vehicles with a 1.5L engine, it is possible the Engine Control Module (ECM) in these vehicles could set a Diagnostic Trouble Code (DTC) for the engineâ s high pressure fuel pump when there is no actual malfunction. If this were to occur, the vehicle could be unnecessarily placed into a reduced engine power mode. Dealers are to reprogram the ECM.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
