P1224 GMC Meaning

The Engine Control Module (ECM) provides voltage to each fuel injector on the injector positive voltage control circuits. The ECM powers each fuel injector by grounding that fuel injector’s control circuit. The ECM monitors the status of the injector positive voltage control circuits and fuel injector control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injectors will be disabled and may disable the related fuel injector group. The Diagnostic Trouble Code (DTC) will be set when the ECM injector output driver detects incorrect current on a fuel injector circuit.

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

P1224 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.

P1225 – Closed Butterfly Position Learning Performance Problem

Meaning of Code P1225

The electronic throttle control actuator consists of a throttle control motor, a throttle position sensor (TP), and other components.

The throttle position sensor (TP) responds to throttle movement and converts the throttle position into a voltage signal sent to the engine control module (ECM).

This system includes two sensors that function as potentiometers and also detect the opening and closing speed of the throttle. The ECM analyzes these signals to precisely adjust the throttle opening angle based on driving conditions.

Code P1225 is triggered when the learned closed throttle position value is excessively low.

Possible Symptoms

  • Check engine light illuminated (or engine service soon warning light).

Possible Causes

  • Faulty electronic throttle control actuator (TP sensor 2)
  • Electronic throttle control actuator (TP sensor 2) harness open or shorted
  • Poor electrical connection in the electronic throttle control actuator (TP sensor 2) circuit

Diagnostic and Repair Procedures

1. Visual Inspection

  • Check the condition of the wiring harness and connectors associated with the electronic throttle control actuator.
  • Look for damaged wires, broken, bent, pushed out, or corroded connector pins.
  • Ensure electrical connections are secure and free from corrosion.

2. Electronic Throttle Control Actuator Check

  • Use a digital multimeter to measure the voltage of the throttle position sensor (TP 2).
  • Compare the obtained values with the manufacturer’s specifications.
  • Replace the actuator if the voltage does not meet the recommended values.

3. Wiring Harness Check

  • Test the continuity of the wires between the ECM and the electronic throttle control actuator.
  • Check for the absence of short circuits or open circuits using a multimeter in ohmmeter mode.
  • Repair or replace any faulty wiring.

4. Engine Control Module (ECM) Check

  • If all previous checks are correct, advanced testing of the ECM module may be necessary.
  • Consult a specialist or qualified technician for an in-depth diagnosis.

Conclusion

Code P1225 indicates a problem with the electronic throttle control actuator circuit, specifically the TP sensor 2. A thorough inspection of the harness, connections, and proper functioning of the electrical components will help identify and resolve the cause of the issue.
