2012年2月15日 · I was having problems with my CEL reading out P0190 (Fuel Rail Pressure Sensor A Circuit) so I replaced the sensor. The CEL went off for a whole 2 weeks (if that) and now it is back on. Same P0190 code as before. **Edit** Im felt a loss in torque after 3500 RPM on the highway. My car doesnt have the usual pick up in the higher RPM that it ...

2009年1月27日 · If the p0190 is coming up chances are it will need a fuel pump.. that code will only come up if it sees insufficient fuel pressure which will be caused by the fuel pump fading when it gets hot. 2002 Infra Red SVTF mods: AEM CAI, MSD Coil Pack and 8.5mm Wires, Jay Racing HFC, custom 3in flex-pipe and exhaust, 67mm TB tuned by: Adam @ S&M ...

2005年3月7日 · P0190 is actually defined as Sensor Stuck In Range. "In Range" means fuel pressure is actually OK, but, the sensor does not seem to be responding to it. According to the above, this can be caused by a loss of a reference voltage signal to the sensor. Backing up a bit: you have a fuel system called an Electronic Returnless Fuel Injection system.

2011年11月21日 · P0190 - Fuel Rail Pressure Sensor Circuit Malfunction (FRP) The comprehensive component monitor (CCM) monitors the FRP sensor to the PCM for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value. VREF open in harness. VREF open in sensor. VREF open in PCM.

2012年11月21日 · P0190 indicates the reference voltage (Vref) from the PCM to the FRPS is not between 4 to 6 V as it should be. This could be a wiring problem (a broken wire between the PCM and FRPS), a bad FRPS, or a bad PCM.

2017年4月14日 · I just got an engine code P0190 & P0193; I've installed new fuel pump, fuel filter, fuel pressure sensor, crank position sensor, Idle Control Valve, EGR Valve, alternator, battery cables, radiator fans, water pump, power steering pump, timing belt kit, serpentine belt, optima battery, silicone hoses, PCV valve and I still have a hesitation with ...

2011年4月15日 · P0190 means that the Vref (reference voltage) signal at the FRP has dropped below the required value (< 4.0V). This can mean a bad FRP, however it could be a wiring issue as well--click here for more. As this is an electrical issue I don't think having removed the parallel pressure relief valve would cause the P0190 DTC.
