P113C 2017 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 2 Not Plausible
Quick Answer
The exhaust gas temperature sensors are variable resistors that measure the temperature of the exhaust gas at the inlet and outlet of the diesel oxidation catalyst as well as the inlet and outlet of the Diesel Particulate Filter (DPF). Common causes include Faulty Exhaust Gas Temperature Sensor, Exhaust Gas Temperature Sensor harness is open or shorted, Exhaust Gas Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

6. How do I fix a P113C code on my Silverado?
Repairs may involve replacing the EGT sensor, repairing damaged wiring, cleaning soot from the exhaust, or reprogramming the ECM if necessary.
7. What is Exhaust Gas Temperature Sensor 2’s role in the Silverado?
EGT Sensor 2 monitors exhaust temperatures downstream to help manage emissions and protect components like the catalytic converter or diesel particulate filter.
8. How much does it cost to repair a P113C code?
Repair costs vary but typically range between $150 and $400, depending on whether the sensor, wiring, or other components need replacement.
9. Can a dirty diesel particulate filter (DPF) cause a P113C code?
Yes, a clogged DPF can lead to abnormal exhaust temperatures, which may trigger implausible readings from the EGT sensor.
