P1493 Chrysler Code - Battery Temperature Sensor Signal Too Low Condition
Quick Answer
With the key on or engine running, then the Powertrain Control Module (PCM) detects that the Battery Temperature Sensor (BTS) value was more than 4.9v for 3 seconds. Common causes include Faulty Battery Temperature Sensor, Battery Temperature Sensor harness is open or shorted, Battery 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.
