P1292 Cng Pressure Sensor Voltage Too High

P1292 Cng Pressure Sensor Voltage Too High

The P1292 CNG pressure sensor voltage too high code indicates that the PCM (powertrain control module) has detected a higher than the normal signal coming from the CNG pressure sensor. The P1292CNG Pressure Sensor Voltage Too High error code indicates that the voltage reading from the CNG (Compressed Natural Gas) pressure sensor in the vehicle’s…

P1293 CNG Pressure Sensor Voltage Too Low

Understanding the P1293 CNG Pressure Sensor Voltage Too Low

P1293 CNG Pressure Sensor Voltage Too Low is an error code that indicates a problem with the pressure sensor on a vehicle equipped with Compressed Natural Gas (CNG) fuel system. This code means that the voltage is sent from the pressure sensor to the engine control module (ECM) is too low. The ECM monitors this…

P1294 Target Idle Not Reached

Common Causes of P1294 Target Idle Not Reached

The P1294 Target Idle Not Reached code indicates that the engine’s idle speed is not reaching the desired or target idle speed as specified by the vehicle’s engine control module (ECM) or powertrain control module (PCM). In other words, the engine is not idling at the speed it’s supposed to under certain operating conditions.This means…
