Having trouble tracking down an electrical issue. 2007 JK keeps going into limp mode ETC light flashing with solid traction control. The code keeps jumping around though. Sometimes it’s a P0340 other times it’s P0344. It was P0405 once. What’s weird is I can get it out of limp mode by disconnecting/reconnecting the coil pack. I’ve already replaced the Camshaft and Crankshaft sensors, the PCM, the EGR, and the coil pack plugs and wires.
Can a weak battery make the code jump around like that? Battery and alternator are about 4 years old.
