P1223 DODGE Meaning

There is a required amount of fuel needed by the fuel system to maintain system stability. The required fuel amount depends on fuel pressure, injection quantity, engine speed, and coolant temperature. The Engine Control Module (ECM) sets “Leak Detected” when the fuel flow exceeds an expected value. When a leak is detected in the system, a counter is started. When the counter reaches a predetermined value, a fault is set and engine derating is activated. When the leak is not detected, the counter counts down, and once the counter is at zero, the engine is returned to normal operating conditions. The Diagnostic Trouble Code (DTC) is set when the counter reaches a calibrated value.

Technical Notes

If only one fuel injector control circuit Diagnostic Trouble Code (DTC) is set, an open circuit or poor connection is the most likely cause. If groups of 4 fuel injector control circuit DTCs are set, suspect a short to ground. Cylinder groups are 2, 3, 5, 8 or 1, 4, 6, 7. More than 4 fuel injector control circuit DTCs indicate a short to voltage in the fuel injector control circuit is the most likely cause.

Possible Symptoms

• Engine Light On (or Service Engine Soon Warning Light)
• Engine misfire
• Rough running

P1223 GMC Meaning

The Engine Control Module (ECM) activates the appropriate fuel injector on the compression stroke for each cylinder. The ECM controls the Fuel Injection Control Module (FICM) by grounding the control circuit through a semiconductor device called a driver. The ECM monitors the driver status. If the ECM detects an incorrect voltage for the commanded state of a fuel injector driver, Diagnostic Trouble Code (DTC) P1223, P1226, P1229, P1232, P1235, P1238, P1241 or P1244 will be set.

P1223 INFINITI Meaning

The electronic throttle control actuator consists of a throttle control motor, throttle position sensor, etc. The throttle position sensor (TP) responds to throttle valve movement.
The throttle position sensor has two sensors. These sensors are a type of potentiometer that convert the throttle valve position into output voltage and send the voltage signal to the engine control module (ECM). Additionally, these sensors detect the opening and closing speed of the throttle valve and transmit voltage signals to the ECM. The ECM determines the current throttle valve opening angle from these signals and the ECM controls the throttle control motor to properly adjust the throttle valve opening angle in response to driving conditions.
