DTCSearch is a free search engine, which has the most up- to- date database of OBD- II diagnostic trouble codes ( DTCs), and allows you to look up generic and manufacturer- specific codes. What Does P0193 Code Mean? OBD- II Code P0193 is defined as a Fuel Rail Pressure Sensor Circuit High Input. The Powertrain Control Module ( PCM) needs to know the fuel pressure at all times so it can effectively control the fuel injectors and deliver the optimal amount of fuel into the engine' s combustion chambers for maximum power and economy while maintaining the lowest tailpipe emissions. Hmm, could be the valve, but since the code says " circuit fault", it could be the wiring also.

The Blazer is rather odd in that it is a 1995, but has an OBDII connector - which I thought was not implemented until 1996. The P1406 code means that the EGR valve is 10% of the expected position by the Powertrain Control Module ( PCM), usually caused by carbon built up n the EGR valve. Service Engine light came on, checked the codes and 1 code came up: P1406. I think that it may be related to the EGR system. Does anyone know what. Códigos DTC FORD Para acceder al modo de prueba, mantenga presionado el botón de reinicio medidor de recorrido y gire la llave a la posición de encendido, entonces los indicadores harán un medidor de barrido y el estado completo en el LCD.
