P242C Code - Exhaust Gas Temperature Sensor 3 Circuit Low Voltage
Quick Answer
The Exhaust Gas Temperature sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) 3, Exhaust Gas Temperature Sensor 3 harness is open or shorted, Exhaust Gas Temperature Sensor 3 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.
