  • Faulty fuel injector
  • Fuel injector harness is open or shorted
  • Poor electrical connection in the fuel injector circuit

How to Fix P1222 CHRYSLER Code?

Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

  • Engine light on (or engine warning light soon on)

P1222 CHRYSLER Meaning

When the engine is running (i.e., the engine is spinning but requires no fuel injection), the only fuel supply needed for the rail is due to natural leakage in the system. Natural leakage directly depends on rail pressure. A defined amount of fuel is needed to overcome natural leakage, for different fuel pressures. 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.

P1222 DODGE Meaning

When the engine is motoring (i.e., the engine is rotating but requires no fuel injection), the only fuel supply needed to the rail is due to natural leakage in the system. The natural leakage is directly dependent on rail pressure. A defined amount of fuel is needed to overcome the natural leakage, for different fuel pressures. 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.

P1223 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 throttle valve position into output voltage and send voltage signals 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 according to driving conditions.

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 on 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 CHEVROLET 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 status of the driver. 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.
