2005 Chrysler 300c $7e8 and $7e9

Question

2005 Chrysler 300 hemi sometimes it starts running rough like a cylinder isn't getting spark but when I turn of an back on it runs fine say $7e8 An 7e9

Answer 1

Those are not code they are menu. 7E8 is for the engine datastream and  7e9 is the data for the transmission. Select 7e8 on you scan tool and gather the engine code that is set, A misfire when you start the engine then turn off and restart, if it seems to run fine you may have a fuel injector issue, try this add a fuel injector cleaner into the fuel tank, With Chrysler engine carbon tends to build up on the exhaust valve

Answer 2

The codes 7E9 and 7E8 are not OBDII codes. When the OBDII scanner plugs in your vehicle, the OBDII scanner gets the 7E9 and 7E8 ($7E9 and $7E8) codes from the ECM. The codes are a menu of systems that the OBDII scanner can access. OBDII scanner interprets the codes and displays the menu. Some scanners can't solve these codes and show the codes instead of the interpretation. Clicking on the code menu will read the OBDII codes (e.g. P0420 or P0455), if any, from that system.

Menu Code 7E8 ($7E8): Engine System

Menu Code 7E9 ($7E9): Transmission System

Menu Code 7EA ($7EA): Engine Management
