What Does P247C Mean?
Exhaust gas temperature at Bank 2, Sensor 1 (pre-catalyst or turbo outlet on opposite cylinder bank) is outside expected range. This mirrors Bank 1 Sensor 1 but for the opposite cylinder bank in V-configuration engines.
Common Causes
38%
Faulty EGT sensor at Bank 2 Sensor 1 location
25%
Exhaust manifold or turbo leak on Bank 2
18%
Cylinder misfire or fuel delivery issue on Bank 2
12%
Bank 2 turbocharger failure or malfunction
7%
Wiring or connector problems at sensor location
Diagnostic Steps
1
Step 1: Compare Bank 2 Sensor 1 temperatures with Bank 1 Sensor 1 to identify bank-specific issues
2
Step 2: Inspect Bank 2 exhaust manifold and turbo connections for leaks
3
Step 3: Check for misfires or rough running specific to Bank 2 cylinders
4
Step 4: Test EGT sensor electrical specifications and response characteristics
5
Step 5: Evaluate turbo operation and boost pressure balance between banks if applicable
Estimated Repair Cost
$200 - $900
Parts + labor, varies by vehicle and location
Exhaust gas temperature at Bank 2, Sensor 1 (pre-catalyst or turbo outlet on opposite cylinder bank) is outside expected range. This mirrors Bank 1 Sensor 1 but for the opposite cylinder bank in V-configuration engines.
The most common cause of P247C (Exhaust Gas Temperature Out of Range Bank 2 Sensor 1) is: Faulty EGT sensor at Bank 2 Sensor 1 location
Typical repair costs for P247C range from $200 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe for limited operation but monitor for performance issues. High temperatures can indicate serious engine problems that may cause damage if continued.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P247C to identify the root cause.
