What is OD pressure switch rationality?

What is OD pressure switch rationality?

One of the most common codes that appear in many Chrysler transmissions is the pressure switch rationality code. This code means that either the switch is not responding, or the switch is activated when it’s not supposed to be on. In 1st and 2nd, there should be zero pressure on the overdrive tap.

What is code P0846?

The P0846 trouble code indicates that the Powertrain Control Module (PCM) has detected an anomalous fluid reading from the transmission system. If the sensor circuit sends a fluid pressure reading to the PCM that falls outside manufacturer specifications, the P0846 trouble code will be stored.

What are symptoms of a bad transmission pressure sensor?

Top Signs of a Failing Transmission Position Sensor

• Car fails to move out of park. When your vehicle is unable to shift out of neutral or park, this is a clear indication that there is a serious problem somewhere in the transition system.
