What P06E5 means
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.

Symptoms of P06E5
- 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
Common causes of P06E5
- Most likelyGlow plug control module faulty internally (drivers do not switch)
- PossiblePoor supply or ground of the module (main feed, fuse, ground)
- PossibleModule overheating (mounting location, short at a plug)
- Less likelyModule software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P06E5 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| E5 | The exact fault in that area. |
What to do next
- Note P06E5 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P06E5
What does P06E5 mean?
P06E5 means "Glow Plug Control Module 1 Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P06E5?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P06E5 fail an emissions test?
Yes, it can. P06E5 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P06E5 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P06E5 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
