If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u016c fault code. Here are the symptoms to look out for:

  • The U016C fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, issues with the transmission, problems with the ABS system, issues with the stability control system, problems with the traction control system, and issues with the cruise control system.
  • It is important to address these symptoms promptly to avoid further damage to the vehicle.

The u016c automobile fault code can be caused by various factors, including a faulty fuel pump control module relay and poor electrical connection.

  • The automobile fault code U016C can be caused by a faulty fuel pump control module relay.
  • Another cause could be a faulty fuel pump control module itself.
  • Additionally, the fuel pump control module harness being open or shorted can also trigger this fault code.
  • Lastly, a poor electrical connection in the fuel pump control module circuit can also be a cause of the U016C fault code.

Below are the possible fixes for the automobile fault code u016c, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u016c, 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 factors that influence the cost of diagnosing and fixing the automobile fault code U016C are the estimated repair time and the hourly rate charged by the auto repair shop. The estimated repair time for this fault code is 1.0 hour. The cost of repair varies between $75 and $150 per hour, depending on the auto repair shop.

These factors should be considered when estimating the total cost of diagnosing and fixing the U016C fault code.

The U016C code is related to the Fuel Pump Control Module ‘B’. The Powertrain Control Module (PCM) monitors the Fuel Pump Monitor 2 (FPM2) circuit for a duty cycled signal.

If the FPM2 circuit is fixed at a low or high voltage, the PCM increments a counter.

The test fails when the PCM doesn’t detect a duty cycled signal on the FPM2 circuit after a calibrated amount of time.

What are the possible causes of the u016c automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u016c automobile fault code. This code is caused by a faulty fuel pump control module relay, a faulty fuel pump control module, an open or shorted fuel pump control module harness, or a poor electrical connection in the fuel pump control module circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the u016c fault code?

If you’re experiencing the u016c fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. First, check the Possible Causes listed above, which include a faulty Fuel Pump Control Module Relay, a faulty Fuel Pump Control Module, an open or shorted Fuel Pump Control Module harness, or a poor electrical connection in the Fuel Pump Control Module circuit. 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.

What are the signs that the Fuel Pump Control Module Relay is faulty and causing the u016c fault code?

If the Fuel Pump Control Module Relay is faulty, it can trigger the u016c fault code, causing the engine light to turn on. Other possible causes include a faulty Fuel Pump Control Module, an open or shorted Fuel Pump Control Module harness, or poor electrical connection in the Fuel Pump Control Module circuit. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.
