What is a P0845 Code?
P0845 code definition The P0845 code is detected with an abnormal voltage reading from the transmission fluid pressure sensor circuit alerts the PCM. This code is often stored with other torque converter clutch, shift solenoid, transmission slippage, gear ratio, or lock up codes.
What does the transmission fluid pressure code p0840 mean?
The P0840 code indicates that there has been an abnormal voltage reading from the transmission fluid pressure sensor circuit. In order to shift gears and provide torque converter lockup, the transmission uses hydraulic pressure, controlled by solenoids, which are controlled by the PCM.
What are the symptoms of a p0845 engine code?
Symptoms of a P0845 engine code may include: Vehicle starts off in 2nd or 3rd gear (limp in mode) Typically the causes for this code to set are: Open in the signal circuit to the TFPS sensor – possible Short to voltage in the signal circuit to the TFPS sensor – possible Short to ground in the signal circuit to the TFPS sensor – possible
What is the diagnostic code for transmission fluid pressure?
P0840 is a diagnostic trouble code (DTC) for “Transmission Fluid Pressure Sensor/Switch A Circuit”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What to do if your transmission fluid pressure sensor is not working?
Use electrical contact cleaner and a plastic bristle brush if cleaning of the terminals is needed. Let dry and apply electrical grease where the terminals contact. If you have a scan tool, clear the diagnostic trouble codes from memory, and see if P0845 code returns. If it does not, then the connections were most likely your problem.

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.
How much does it cost to repair a Nissan p0840?
The cost of diagnosing the P0840 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
Why is my transmission fluid pressure sensor not working?
Typically the causes for this code to set are: Open in the signal circuit to the TFPS sensor – possible Short to voltage in the signal circuit to the TFPS sensor – possible Short to ground in the signal circuit to the TFPS sensor – possible Failed TFPS Sensor – likely Internal mechanical transmission issue – possible
