<<See All OBD Codes

The trouble code P0904 can be explicated as Gate Select Position Circuit. The P0904 code would start indicating when the electronic control module or ECM would detect an issue with the gate select position sensor circuit. This error code might also be accompanied by the P0905, P0906, P0907, or P0908 codes. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P0904 trouble code. A lot of sensors are used by the TCM and ECM to monitor as well as control the overall performance of the transmission in the latest vehicles. Out of those, one sensor is the gate select position sensor, which would tell the TCM as well as ECM that in which gear position the driver should put the automobile in.

What causes this problem with the Gate Select Position Circuit?

• Faulty electrical connections
• Malfunctioning wire harnesses
• Sensor might be flawed
• Some issues related to the loose connections
