P06E5Glow Plug Control Module 1 Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
