The P181E fault code refers to a problem with the Internal Mode Switch 2 R2 Circuit’s low voltage.

This switch assembly is part of the automatic transmission manual shift shaft position switch assembly, which is located within the transmission’s control valve body.

The switch assembly has nine outputs, four of which are range selection inputs to the transmission control module (TCM) and five are direction selection inputs to the hybrid powertrain control module. The range inputs are represented as TCM scan tool parameters, while the direction inputs are represented as hybrid powertrain control module scan tool parameters. When a switch is open, the input voltage at the modules is high, and when a switch is closed to earth, the input voltage is low.

Each control module independently supplies power and earth to its respective switch assembly.

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

What are the possible causes for the automobile fault code p181e?

If you see the engine light or service engine soon warning light on, the fault code P181E 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 pins on the connectors. Taking these steps can help resolve the issue and get your automobile back on track.

How can I visually inspect the wiring harness and connectors to fix the p181e fault code?

If you’re dealing with the p181e fault code and your engine light is on, it’s time to take action. The most likely cause is a faulty Manual Shift Shaft Position Switch Assembly or issues with its harness and electrical connection. To fix it, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This step is crucial in identifying and resolving the issue.

What should I look for when checking for damaged components and connector’s pins to resolve the p181e fault code?

When resolving the p181e fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing this, you can identify any issues with the Manual Shift Shaft Position Switch Assembly and its circuit connections. This will help you determine if the fault lies in a faulty switch assembly or if there is a problem with the electrical connection.
