What is code P0840?
P0840 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).
What does the p0840 OBD-2 trouble code mean?
P0840 code definition The P0840 code indicates that there has been an abnormal voltage reading from the transmission fluid pressure sensor circuit. What the P0840 code means In order to shift gears and provide torque converter lockup, the transmission uses hydraulic pressure, controlled by solenoids, which are controlled by the PCM.
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.
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.

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
