DTC 190E - What is it?

[V_Eight]

Is it "P0190 FRP Sensor Signal Low."?

I don't remember a P in front of it at all. I just remember it saying "DTC 190E" on the cluster.

If it's P0190, Fuel Rail Pressure Sensor Circuit Malfunction:

The comprehensive component monitor (CCM) monitors the FPP 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. The voltage should be between 4.0v and 6.0v.

Possible causes are listed as:

VREF open in harness. VREF open in sensor, VREF open in PCM.

I guess I'd start by checking the connection to the harness at the sensor on the fuel rail. Have you made any modifications to the fuel system?

Haven't touched it. It came on en route to a car show.

Reset the PCM. Maybe it will not come back...

Going to have to try that.

Had any problems driving it since you've seen the code? Could always be a "ford fluke."

Nope, it hasn't changed a bit.
