P06E5 Glow Plug Control Module 1 Performance

Limp modeNo

P06E5 means glow plug control module 1 does not respond correctly to the glow command: its outputs do not switch or its internal drivers report faults or overheating. Ford's 2023 6.7 L and 3.0 L Power Stroke list P06E5 among the glow module checks, run continuously, with a fault after about 1 s when internal drivers for glow plugs, DEF heaters or relays fail to switch or overheat for more than 1 s – Ford does not assign each threshold to a single code. GM files the same check under P064C: on the L5P a plug commanded on but drawing under 3.2 A with 0 V at the plug for 3.5 s, on the LML a total current under 6.6 A; both after two trips. The plugs then heat partly or not at all, with hard cold starts and white smoke. There is no limp mode.

Likely causes

Glow plug control module faulty internally (drivers do not switch)
Poor supply or ground of the module (main feed, fuse, ground)
Module overheating (mounting location, short at a plug)
Module software

Symptoms

  • Check engine light, possibly glow plug/wait-to-start lamp
  • Hard cold start, long cranking
  • White smoke and rough running after cold start
  • Often stored together with plug codes or P064C/P263C
