DTC P246E — Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4 (DPF Post-Filter)
DTC P246E is a standardized diagnostic trouble code defined as "Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4 (DPF Post-Filter)" within the DPF / EGT Calibration subsystem. In DaVinci Deluxe Cloud Edition (v1.0.44), workshops can diagnose root causes or apply deterministic off-road/motorsport subsystem & path-level P246E deactivation on a 100% virgin original ECU file.
🛟 24h/7 Live Engineering Support (365 Days / Including All Holidays): Direct step-by-step diagnostics & calibration engineering in every language (live logs, DTC scans, photos, videos & audio supported) until your car, 24V truck, tractor or marine vessel runs 100% flawlessly.
Engineering Breakdown for Fault Code P246E
| Diagnostic Parameter | Technical Specification for P246E |
|---|---|
| Fault Code Identifier | P246E (SAE J2012 / ISO 15031-6 Powertrain) |
| Official Definition | Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4 (DPF Post-Filter) |
| Primary ECU Subsystem | DPF / EGT Calibration |
| Limp-Mode & Derate Impact | Triggers MIL / glow-plug lamp, blocks active regeneration, reduces boost/fuel torque request, and elevates exhaust backpressure. |
| Workshop Pre-Check | Inspect harness continuity, +5V/+12V/+24V reference supply, live sensor plausibility, and mechanical component integrity before any software modification. |
| Off-Road / Motorsport Calibration | Upload a 100% virgin unmodified original ECU binary at https://www.davincideluxe.fr/online-ecu-tuning to apply complete DPF / EGT Calibration calibration or selective path-level P246E fault-class deactivation while keeping engine oil, temperature, and rail-pressure safety intact. |
