What causes code P0193?

What causes code P0193?

If the PCM receives a signal from the fuel rail pressure sensor that is abnormally high over a set period, the P0193 code is set. Code P0193 may be set if the PCM receives a signal from the fuel rail pressure sensor that is abnormally high over a set period.

What can cause high fuel rail pressure?

Fuel pressure that is too high, can cause the engine to run too rich. Common causes of high fuel pressure include; a bad fuel regulator or a clogged return line.

Can high fuel pressure damage injectors?

High fuel pressure results in a rich air-fuel ratio because the increase in pressure forces more fuel through the injectors than required producing increased emissions (HC’s) and black sooty exhaust. These excessive hydrocarbons overheat and damage the catalytic converter.

What causes a p0193 code on the ECU?

The most likely problem is the sensor itself. If all tests have passed so far, and you continue to get a P0193 code, this would most likely indicate a failed FRP sensor, although a failed PCM could not be ruled out until the sensor had been replaced. CAUTION!

What does the p0193 Ford fuel rail pressure sensor do?

P0193 Ford Description. The FRP sensor is a diaphragm strain gauge device. The FRP sensor measures the pressure difference between the fuel rail and atmospheric pressure. The FRP sensor nominal output varies between 0.5 and 4.5 volts, with 0.5 volts corresponding to 0 MPa (0 psi) gauge and 4.5 volts corresponding to 26 MPa (3771 psi) gauge.

How much does it cost to diagnose a p0193 Ford code?

The cost of diagnosing the P0193 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. | What are P0193 FORD code possible symptoms? Engine Light ON (or Service Engine Soon Warning Light)
