P2469Exhaust Gas Temperature Sensor Circuit High (Bank 2 Sensor 3)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2469 is logged when bank 2 probe number 3 pushes its input above the permitted ceiling. An unplugged connector, a broken wire or a burnt-out sensing element produces exactly that, as does a signal line shorted to a voltage source. Public calibrations exist only for the sister inputs: Ford's 2023 diesels flag anything above 2.66 V, and GM's 2025 diesel tables treat an open-like resistance (beyond 100 MΩ) or a digital value hotter than roughly 1,290 °C as failed after 19 of 25 samples and rate it Type A, so the MIL comes on in the first trip. CARB requires that out-of-range highs on emission inputs are detected. Measure the probe resistance cold and check the plug before buying a sensor. A too-low signal is P2468, an erratic one P246A.
- What you may notice
- MIL on, often already in the first trip
- Probe shows a maximum or invalid value
- Regeneration or DEF dosing inhibited
- Likely causes
- LikelyConnector unplugged or wire broken (open circuit)
- PossibleSensing element burnt out
- RareSignal line shorted to a voltage source
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
