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.
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 p0840 transmission fluid pressure sensor not working?
If all prior tests have passed and you continue to get a P0840, this would most likely indicate a failed TFPS sensor, although a failed PCM/TCM could not be ruled out, nor could internal transmission malfunctions until the TFPS sensor had been replaced. If unsure, seek assistance from a trained automotive diagnostician.
When does the diagnostic trouble code set on a Nissan?
The Diagnostic Trouble Code (DTC) will set when the TCM detects no signal from the Transmission Fluid Pressure Sensor ‘A’. Need more information on how to fix the P0840 NISSAN code?

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
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.
What does the code p0715 mean on a transmission?
Code P0715 is triggered when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects an irregular signal coming from the input/turbine speed sensor in the transmission. The input/turbine speed sensor is used to measure how many revolutions per minute (RPM) the input shaft of the transmission is turning.

What does OBD-II engine diagnostic code mean?
What does that mean? This generic powertrain/engine diagnostic trouble code typically applies to all OBD-II equipped vehicles including but not limited to Nissan, Dodge, Chrysler, Honda, Chevrolet, GMC, Toyota, etc. but seems to be most commonly seen on Nissan vehicles.
