What Does P247E Mean?
The exhaust gas temperature (EGT) sensor 3 on bank 2 is reading a temperature outside the expected range. This typically occurs downstream of the diesel particulate filter (DPF) or catalytic converter. The PCM has detected either an implausibly high or low temperature reading.
Common Causes
45%
Failed or degraded EGT sensor providing inaccurate readings
25%
Exhaust leaks near sensor causing false temperature readings
20%
DPF regeneration issues causing abnormal exhaust temperatures
10%
Wiring harness damage or corrosion at sensor connector
Diagnostic Steps
1
Step 1: Monitor live data for EGT sensor 3 Bank 2 and compare temperature readings with adjacent sensors during various operating conditions
2
Step 2: Visually inspect sensor and exhaust system for physical damage, carbon buildup, or exhaust leaks near sensor location
3
Step 3: Check sensor wiring and connector for corrosion, damaged insulation, or loose connections
4
Step 4: Measure sensor resistance when cold and compare to specifications (typically 200-500 ohms at room temperature)
5
Step 5: If sensor tests good, inspect DPF for excessive backpressure or regeneration problems
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The exhaust gas temperature (EGT) sensor 3 on bank 2 is reading a temperature outside the expected range. This typically occurs downstream of the diesel particulate filter (DPF) or catalytic converter. The PCM has detected either an implausibly high or low temperature reading.
The most common cause of P247E (Exhaust Gas Temperature Out of Range Bank 2 Sensor 3) is: Failed or degraded EGT sensor providing inaccurate readings
Typical repair costs for P247E range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Generally safe to drive short distances, but prolonged operation may cause DPF damage or enter limp mode. Exhaust system problems could pose fire risk if leaks are severe.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P247E to identify the root cause.
