If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2149 fault code.

Here are the symptoms to look out for:

  • The P2149 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, and poor acceleration.
  • Additionally, the vehicle may experience misfires, reduced fuel efficiency, and difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p2149 can be caused by a faulty fuel injector, open or shorted harness, poor electrical connection, or a faulty ECM.

  • The automobile fault code P2149 can be caused by a faulty fuel injector 2.
  • It can also be caused by an open or shorted fuel injector 2 harness.
  • Poor electrical connection in the fuel injector 2 circuit can also trigger this fault code.
  • Lastly, a faulty engine control module (ECM) can also be a cause of the P2149 fault code.

To fix the p2149 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2149, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2149 is related to a fuel injector group circuit malfunction.

The diagnosis and fixing cost of this fault code is influenced by the estimated repair time, which is 1.0 hour. The cost of repair is also affected by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing of the P2149 fault code will depend on the repair time and the hourly rate charged by the auto repair shop.

The P2149 code is related to the fuel injector circuit in Cylinder 2 of the engine.

The Engine Control Module (ECM) supplies voltage to each fuel injector on the high control circuits.

The ECM energizes each fuel injector by grounding the low control circuit of the fuel injector. When the ECM detects that the fuel injector high voltage supply circuit is not to factory specifications, it disables the affected fuel injector(s).

This results in the P2149 code being set, indicating an issue with the Cylinder 2 Injector High Control Circuit.

What are the possible causes of the P2149 fault code in an automobile?

If you’re experiencing the P2149 fault code in your automobile, it could be due to a faulty fuel injector 2, an open or shorted fuel injector 2 harness, a poor electrical connection in the fuel injector 2 circuit, or a faulty engine control module (ECM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the wiring harness and connectors related to the P2149 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2149 fault code, there are a few possible causes to consider. These include a faulty fuel injector 2, an open or shorted fuel injector 2 harness, poor electrical connection in the fuel injector 2 circuit, or a faulty Engine Control Module (ECM). To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the steps to take when checking for damaged components and corroded connector’s pins in relation to the P2149 fault code?

If you’re experiencing the P2149 fault code, start by checking for a lit Engine Light or Service Engine Soon Warning Light. The cause could be a faulty Fuel Injector 2, an open or shorted Fuel Injector 2 harness, a poor electrical connection in the Fuel Injector 2 circuit, or a faulty Engine Control Module (ECM). To fix the issue, visually inspect the related wiring harness and connectors, checking for damaged components and looking for broken, bent, pushed out, or corroded connector’s pins.

p2149 error fault code explained

If your engine light is on and the code is p2149, it could be due to a faulty fuel injector 2, open or shorted harness, poor electrical connection, or a faulty ECM. Visually inspect the wiring harness and connectors for damage or corrosion.

Check for broken, bent, or pushed out pins.
