What are the symptoms of engine code p0846?
Symptoms of a P0846 engine code may include: 1 Malfunction Indicator Light On 2 Change in shift quality 3 Vehicle starts off in 2nd or 3rd gear (limp in mode)
What’s the difference between po0700 and po846?
PO846 refers to Transmission Fluid Pressure Sensor/Switch B Circuit Range/Performance. P0700 is just to let you know that another code has set, most likely it’s refering to the P0846. This code is for information only – check for other TCM codes.
What are the possible causes of po0846?
P0846 possible causes are: 2/4 pressure is incorrect, or internal transmission faults exist, 2/4 pressure switch circuit is open, shorted to ground or power, 2/4 pressure switch is damaged or it has failed and/or the TCM relay power circuit to L/R switch is open (loss of B+).
What causes p0846 transmission fluid pressure sensor switch B circuit?
P0846 is typically an electrical circuit (TFPS sensor circuit) issue, although as previously stated this code may also be set due to mechanical issues (internal leaks, cracked or missing check balls in the valve body, low system operating pressure/main line pressure, stuck valve in the valve body).

How to test the p0846 transmission fluid pressure sensor?
If the P0846 code does return, we will need to test the TFPS sensor and its associated circuits. With the Key Off, disconnect the electrical connector at the TFPS sensor. Connect a Digital Voltmeter (DVOM) black lead to the ground or low reference terminal at the TFPS sensor wiring harness connector.
