What Does P2468 Mean?
The EGT sensor 3 on Bank 2 is reporting voltage below the acceptable threshold, indicating an open circuit, short to ground, or sensor reading abnormally low temperatures. This prevents proper monitoring of post-DPF exhaust temperatures.
Common Causes
35%
Open circuit or short to ground in EGT sensor 3 wiring
30%
Failed EGT sensor 3 with internal short or open
20%
Corroded or damaged sensor connector terminals
10%
Broken sensor wire at connector or sensor body
5%
Poor ground connection in sensor circuit
Diagnostic Steps
1
Step 1: Check voltage at EGT sensor 3 connector with key on; should read reference voltage (typically 5V)
2
Step 2: Measure sensor resistance and compare to temperature-resistance chart specifications
3
Step 3: Inspect connector terminals for corrosion, bent pins, or moisture; clean or repair as needed
4
Step 4: Test circuit continuity from sensor connector to ECM; check for shorts to ground
5
Step 5: Replace EGT sensor 3 if sensor tests faulty; repair wiring if circuit fault is found
Estimated Repair Cost
$200 - $600
Parts + labor, varies by vehicle and location
The EGT sensor 3 on Bank 2 is reporting voltage below the acceptable threshold, indicating an open circuit, short to ground, or sensor reading abnormally low temperatures. This prevents proper monitoring of post-DPF exhaust temperatures.
The most common cause of P2468 (Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 3) is: Open circuit or short to ground in EGT sensor 3 wiring
Typical repair costs for P2468 range from $200 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but DPF regeneration will be inhibited or operate in failsafe mode. This may lead to DPF clogging over time or prevent regeneration cycles from initiating.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2468 to identify the root cause.
