Since there is no "Check Transmission Light," the ECM sets an informational DTC P0700 and illuminates the MIL or CEL (malfunction indicator lamp or check engine light). Since DTC P0700 simply refers to a ...The manufacturer's TSB database is the first place you should look when you start to diagnose a P0878 OBDII trouble code. The wiring and connectors leading to the transmission fluid pressure sensor are the second place to look, because shorted wires or corroded connectors can prevent the TFPS sensor from working.

The automobile fault code P0846 indicates a problem with the Transmission Fluid Pressure SensorSwitch ‘B’. This can cause the Engine Light to turn on or the Service Engine Soon Warning Light to illuminate. The possible causes include a faulty sensorswitch, an open or shorted harness, or a poor electrical connection in the circuit.
