P1292 Code - Compressed Natural Gas Pressure Sensor Signal Too High
Quick Answer
With the key on or engine running, then the Powertrain Control Module (PCM) detects that the Compressed Natural Gas (CNG) Fuel Pressure sensor input was more than 0.49v. Common causes include Faulty Compressed Natural Gas (CNG) Pressure Sensor, CNG Pressure Sensor harness is open or shorted, CNG Pressure 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.
