ALLISON AT Code (DTC) P1769 AG4 Transmission Torque Modulation Fault ALLISON AT Code (DTC) P1770 Clutch Solenoid Circuit Malfunction ALLISON AT Code (DTC) P1775 Transmission System MIL Fault

How to test the p0845 transmission fluid pressure sensor?

If the P0845 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.

Is the p0845 a power related fault code?

A good example of this would be if there are any known power related codes set along with the P0845, or if there is more than one pressure sensor/switch code set. If so, begin your diagnosis with the power related fault code first, or with the multiple code diagnosis first, as this may be the reason for the P0845.
