P263EGlow Plug Control Module 1 Over Temperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- The first glow plug control module measures its own internal temperature and reports P263E when it runs too hot, since its power semiconductors carry tens of amps during glowing. GM's 6.6 L L5P Duramax tables set it at a module temperature above 123 °C while the plugs are commanded on and coolant is below 60 °C, type B. Ford's 2023 diesel summary for the 6.7 L and 3.0 L names more than 125 °C inside the module. FCA bulletin 09-009-15 for 2014-15 Ram ProMaster vans with the 3.0 L diesel lists P263E among glow plug codes caused by plugs lacking an internal O-ring and replaces all four plugs. Heat can also come from repeated or very long glow cycles in deep cold. Driver faults are P263C, a second module would report P263F.
- What you may notice
- Check engine light, glow lamp flashing
- Glowing cut short, hard cold starts
- White smoke after cold start
- Likely causes
- LikelyDefective glow plugs drawing excess current (e.g. Ram ProMaster plugs without O-ring)
- PossibleRepeated start attempts or very long glow periods in severe cold
- PossibleInternal fault or poor heat dissipation of the glow plug module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
