To fix the automobile fault code p184a, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P184A, follow these steps: 1.
  • Check the possible causes mentioned above.
  • 2.
  • Visually inspect the wiring harness and connectors related to the fault code.
  • 3.
  • Look for any damaged components.
  • 4.
  • Check for broken, bent, pushed out, or corroded pins in the connectors.
  • The estimated repair time for this fix is 1.0 hour.

The automobile fault code P184A has an estimated repair time of 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for this type of repair.

The P184A fault code refers to the Internal Mode Switch 2 S Circuit Low Voltage. This code is related to the automatic transmission manual shift shaft position switch assembly, also known as the internal mode switch assembly. The internal mode switch assembly contains two sliding hall-effect switch assemblies that are attached to the control valve body within the transmission.

These switches indicate which position is selected by the transmission manual shaft. The P184A code specifically indicates that there is a low voltage issue in the circuit for Internal Mode Switch 2 S. This means that the input voltage at the hybrid powertrain control module is low when the switch is closed to earth.

It’s important to note that the hybrid powertrain control module is internal to the power inverter module and is not serviced separately.

This means that if you encounter the P184A fault code, you may need to address the low voltage issue in the circuit for Internal Mode Switch 2 S within the power inverter module.

What are the possible causes for the automobile fault code P184A?

If you see the engine light or service engine soon warning light on, the fault code P184A could be the culprit. This code is often caused by a faulty manual shift shaft position switch assembly or issues with the assembly’s harness. To fix the problem, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, start by checking the possible causes mentioned above. Then, visually inspect the wiring harness and connectors related to the Manual Shift Shaft Position Switch Assembly. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This thorough inspection will help identify any issues with the wiring and connectors and allow for appropriate fixes to be made.

What should I look for specifically when checking for damaged components or corroded connector pins?

When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a faulty Manual Shift Shaft Position Switch Assembly or issues with its harness and electrical connection. To check for damaged components or corroded connector pins, visually inspect the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins on the connectors. This thorough inspection will help identify and fix the problem effectively.
