What Does P2469 Mean?
The exhaust gas temperature sensor 3 on bank 2 is reporting an abnormally high voltage signal, indicating a circuit fault. This sensor typically monitors temperature after the diesel particulate filter or catalytic converter.
Common Causes
35%
Damaged or shorted EGT sensor wiring harness
30%
Failed exhaust gas temperature sensor (internal short)
20%
Corroded or damaged sensor connector terminals
10%
Short to voltage in sensor circuit
5%
Failed engine control module (ECM)
Diagnostic Steps
1
Step 1: Visually inspect EGT sensor 3 bank 2 wiring and connector for damage, corrosion, or shorts to other wires
2
Step 2: Disconnect the EGT sensor and measure resistance across sensor terminals (typically 200-1000 ohms at room temp)
3
Step 3: Check for continuity and shorts to voltage/ground in the wiring harness between sensor and ECM
4
Step 4: Monitor live data for EGT sensor voltage with ignition on, engine off (should read 0.2-0.8V typically)
5
Step 5: If all circuits test normal, replace the EGT sensor and retest
Estimated Repair Cost
$150 - $450
Parts + labor, varies by vehicle and location
The exhaust gas temperature sensor 3 on bank 2 is reporting an abnormally high voltage signal, indicating a circuit fault. This sensor typically monitors temperature after the diesel particulate filter or catalytic converter.
The most common cause of P2469 (Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 3) is: Damaged or shorted EGT sensor wiring harness
Typical repair costs for P2469 range from $150 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive short distances but may enter reduced power mode. Continued operation can damage the DPF or catalytic converter.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2469 to identify the root cause.
