Purpose of the Mazda CX-5 automatic transmission selector switch

The limit switch of the automatic transmission selector (automatic transmission) in the Mazda CX-5 is used to transmit information about the selected position of the gear selector to the electronic control unit (ECU) of the automatic transmission.

Limit switch location

The automatic transmission selector switch is located on the gear shift mechanism, usually under the center armrest console.

Operating principle

The selector switch is an electrical switch that makes or opens contacts depending on the position of the selector lever. Each selector position corresponds to a specific combination of closed and open contacts.

Information transmitted by the automatic transmission ECU

The automatic transmission ECU uses information from the selector lever to determine the following:

* Selector position (P, R, N, D, S, etc.)
* Is engine starting allowed by the current selector position?
* Is it necessary to lock the selector to prevent accidental gear shifting?

Symptoms of a faulty automatic transmission selector switch

Signs of a faulty automatic transmission selector switch may include:

* Inability to start the engine with selector positions other than P or N
* Spontaneous gear shifting
* Shocks or jerks when shifting gears
* Display of incorrect selector position on the instrument panel

Replacing the limit switch

Replacing the automatic transmission selector switch usually requires removing the gear shift mechanism. This procedure can be complex and it is recommended that you contact a qualified mechanic.
