P06E0Cylinder 11 Glow Plug Control Circuit Low
- 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
- Diesel glow systems switch each plug through its own power semiconductor and switch off a faulty channel; CARB requires single-plug detection from model year 2010. P06E0 means the circuit to the cylinder 11 glow plug is shorted to ground or draws overcurrent. For cylinders 1–8, GM's engine-module drivers flag below 0.11 Ω to ground after two trips, and Ford's 2023 Power Stroke more than 22 A for 0.3 s or 20–22 A for 2 s while heating. The channel is switched off and the plug stays cold; the other plugs keep working. An internally shorted plug or a chafed wire is the usual cause. No manufacturer document available to us uses this code – it needs at least 11 cylinders, and the only US OBD II diesel above eight, VW's Touareg V10 TDI, has ten; the description follows cylinders 1–8.
