So

year make model P0193

Diagnostic Trouble Code (DTC) P0193 stands for "Fuel Rail Pressure Sensor "A" Circuit High." It is logged when the PCM perceives that the signal from the fuel rail pressure sensor exceeds the calibrated limit over a specified amount of time.Aug. 24, 2021

P0193 Code: Fuel Rail Pressure Sensor "A" Circuit High

P0175 OBD-II Trouble Code: P0175 System Too Rich (Bank 2)

P0175 indicates that the Engine Control Module (ECM) detects too much fuel and not enough oxygen in the air fuel ratio (AFR). This code will set when the ECM ...

P0172 OBD-II Trouble Code: System Too Rich (Bank 1)

https://www.yourmechanic.com > Articles
P0172 indicates that there is too much gasoline being detected in the exhaust gases exiting the combustion chamber. The ECU uses a number of instruments, such ...

Fuel pressure outside nominal range. Check pressure at fuel rail.

Fault Code Definition P0193

• Fuel Rail Pressure Sensor Circuit High Input

What does this mean?
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.
Code P0193
indicates that the signal from the Fuel Rail Pressure Sensor and/or its circuit is too high, indicating a fuel pressure condition that is abnormally high.

Here's a video on your code. Check engine light diagnosis code P0193 Part 1

Points to fuel temperature & pressure sensor or sensors. Simple to check, just disconnect and read ohms. May just be a loose connector or wire. Not a very expensive part to have to replace.

p0193 sounds like a ip sensor circuit malfunction the p1111 is system check has been completed p1000 system check is not completed..that number will check from 1000 to 1111 when the car has ran a complete self check of itself.

If you have replaced the sensor, check the wires at the back of the plug. Pull them one at a time, if they stretch it is a broken wire. When you get a high reading code. It is either it's unplugged or a wire is broken.

Still i have p0193 fault and no pick computersay fuel rail sensor but i was diconect the first injector electric swich then this pro

first find out what the code is for. call autozone and tell them to look up the code and they will be able to give you a list of possiable causes, then go on and make your decision as to what you are going to do to fix the problem

This code P0560

Fault Code:- P0560 Indicates a Power-train fault


The fault is generally due to a problem in the Vehicle Speed & Idle Control area


Fault Description: Battery power supply voltage malfunction Note: This DTC can be flagged due to fuel injection pressure sensor fault. If P0193 is also flagged, correct first.

Action of ECM:- none


After clearing the DTC, complete the Engine temperature cool (cooling fans not running) Remove ignition key for 20 seconds (cooling fans not running) Ignition key in, position II for 5 seconds (do not start) Repeat cycle two additional times
Check for a reoccurrence of fault DTC.

Possible Fault:- ECM battery power supply open circuit, high resistance
