Hi JACUSTOMER-8osomi95, Thank you for using JustAnswer.

 

There is a TSB for this condition. The PCM (computer) needs to be reprogramed. See below.

 

Engine Controls - MIL ON/Misfire DTC's Set

Group FUEL SYSTEM

Number 10-FL-004

Date JANUARY, 2010

Model
2007-2009 ACCENT (MC)

 

Subject
ECM UPDATE - MIL ON DTC P0300, COMBINED WITH P0301- P0304

 

NOTE:
This bulletin revises bulletin 08-FL-009-1 to provide ECM Update Event #179 to address DTC P0300 for 2007-2009 MY Accent (MC) vehicles.

 

DESCRIPTION:

This bulletin provides the procedure to update the Engine Control Module
(ECM) of some 2007-2009 ACCENT (MC) 1.6L vehicles which may experience either or both:

 

^DTC P0300 combined with one or more of DTC P0301 - P0304.

 

^Engine roughness at initial cold idle

 

NOTE:
This ECM update addresses engine roughness that occurs only within the first minute of idle after cold start with coolant temperature in the range of 32-70F. If engine misfire continues beyond this period, follow the service manual DTC P0300 diagnostic procedures as an ECM Update will not resolve this type of incident.

 

APPLICABLE VEHICLES: 2007 - 2009 ACCENT (MC) vehicles with 1.6L engines

NOTE:
To verify the vehicle is affected, be sure to check the version of the vehicle's control unit ROM ID with reference to the ROM ID Information Table below before attempting to update the control unit software.
The P703 is for the brake light switch. There was a recall on the brake light switch. The dealer can check for open recalls when you go in for the PCM reprogram.
