P0849

DTC P0849, sometimes indicated as P084900 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing transmission fluid pressure sensor/switch "b" circuit intermittent.

The Transmission Fluid Pressure Sensor/Switch "B" Circuit Intermittent is a problem with the sensor that monitors the pressure of the transmission fluid. This can cause the transmission to not function properly, or even to fail.
There are several possible causes of this problem. One is a bad sensor, but there can also be a problem with the wiring or connector, or with the electronic control module (ECM) that monitors the sensor.
The best way to solve this problem is to first determine what is causing it. This can be done by checking the sensor, the wiring, the connector, and the ECM. If any of these are found to be defective, they will need to be replaced.
