If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p2674 fault code.

Here are the symptoms to look out for:

  • The P2674 fault code in an automobile 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, poor acceleration, rough idling, stalling, and difficulty shifting gears.
  • Additionally, the vehicle may experience transmission slippage, decreased fuel efficiency, and an increase in emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2674 fault code can be caused by a faulty injection pump, open or shorted injection pump harness, or poor electrical connection.

  • The automobile fault code P2674 can be caused by a faulty injection pump.
  • It can also be caused by an open or shorted injection pump harness.
  • Additionally, a poor electrical connection in the injection pump circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2674, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code P2674, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 P2674 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of fixing the P2674 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2674 code is related to the Injection Pump Timing. The Powertrain Control Module (PCM) is responsible for monitoring the Injection Pump Timing. If the Injection Pump Timing is not within factory specifications, the PCM will set the P2674 code.

This code indicates that the Injection Pump Fuel Calibration is not leaking.

What are the possible causes of the P2674 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2674 fault code. This code is caused by a faulty injection pump, an open or shorted injection pump harness, or a poor electrical connection in the injection pump circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2674 fault code?

If you’re experiencing the P2674 fault code, start by checking the possible causes listed above. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
