P242B RAM Code - Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 3
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 3, Exhaust Gas Temperature Sensor Bank 1 Sensor 3 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 1 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.
