[QUOTE="Vinnie_B, post: 16769223, member: 201678"] 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 [COLOR=rgb(184, 49, 47)]Verify VREF voltage between 4.0 and 6.0V.[/COLOR] If it isnt, you got a harness,sensor or PCM issue: Check the following possibilities [LIST] [*]VREF open in harness. (Bad wiring or broken wire in harness) [*]VREF open in sensor. (Bad Fuel Rail Pressure Sensor) [*]VREF open in PCM. (Bad PCM) [/LIST] [/QUOTE]
