When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p18be fault code.

  • The symptoms of the automobile fault code p18be include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p18be can be caused by a faulty Transmission Internal Mode Switch, an open or shorted harness, a poor electrical connection in the circuit, or a faulty Transmission Control Module (TCM).

  • The fault code P18BE can be caused by: a faulty Transmission Internal Mode Switch, an open or shorted harness for the Transmission Internal Mode Switch, a poor electrical connection in the Transmission Internal Mode Switch circuit, or a faulty Transmission Control Module (TCM).

To fix the automobile fault code p18be, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p18be, you need to 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.

The automobile fault code P18BE has an estimated repair time of 1.0 hour.

The cost of fixing this fault code will depend on the repair shop’s hourly rate, which typically ranges between $75 and $150.

The P18BE fault code refers to the Internal Mode Switch ‘S’ Circuit Stuck Off Invalid Voltage Range. This code is related to the Transmission Control Module (TCM) and indicates that the TCM has detected an issue with the internal mode switch.

The internal mode switch consists of 5 separate hall effect switches, each supplied with a 9V reference circuit and a signal circuit from the TCM. These switches indicate the gear position selected by the vehicle operator.

Each signal circuit for each gear selector position will have a specific voltage reading. A voltage reading of 0.70-0.96V indicates the switch is on, while a reading of 1.68-2.38V indicates the switch is off.

The voltage values on each internal mode switch circuit change depending on the gear selector position. When the TCM detects that the internal mode switch ‘S’ signal circuit has an invalid voltage range of 1.68-2.38V for 2.7 seconds, it sets the P18BE fault code. This indicates that there is a problem with the internal mode switch circuit.

If you encounter this fault code, it is recommended to have the internal mode switch circuit checked and repaired by a qualified technician.

Ignoring this issue could lead to further transmission problems and potential safety risks.

What are the possible causes of the automobile fault code P18BE?

If you see the engine light on or the service engine soon warning light, the fault code P18BE might be the culprit.
