The P1A16 fault code in automobiles can be caused by a range of issues, including a faulty inverter and variable voltage controller.

  • The automobile fault code P1A16 can be caused by a faulty inverter.
  • It can also be caused by a faulty variable voltage controller.
  • Another cause of this fault code is an open or shorted variable voltage controller harness.
  • Poor electrical connection in the variable voltage controller circuit can also trigger this fault code.
  • Lastly, a malfunction in the high voltage traction battery can cause the P1A16 fault code to appear.

Below are the possible fixes for the automobile fault code p1a16, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1A16, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 fault code P1A16 indicates an issue with the hybrid battery pack coolant temperature sensor circuit. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P1A16 fault code is related to the Battery Energy Control Module (BECM) in an automobile. This code indicates that there is a malfunction in the Variable Voltage Controller or traction battery.

The BECM monitors the Variable Voltage Controller Voltage, and if it detects an issue, it will trigger the P1A16 code.

If you see this code on your vehicle, it is important to have it diagnosed and repaired as soon as possible to avoid further damage.

What are the possible causes of the P1A16 automobile fault code?
