What is Tfps sensor?
Your vehicle’s TFPS, also known as Transmission Fluid Pressure Sensor is located to the side of your valve body in your vehicle’s transmission system. It is responsible for converting the mechanical transmission pressure into an electrical signal for the TCM/PCM.
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.
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 should I look for in a p0840 Nissan?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The bulletin suggests replacing the transmission valve body. What does this mean? The cost of diagnosing the P0840 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
What to do if transmission fluid pressure sensor is not working?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The bulletin suggests replacing the transmission valve body.

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.
What does the Transmission Control Module p0840 do?
P0840 Description. The Transmission Control Module (TCM) monitors the Transmission Fluid Pressure Sensor/Switch signal. The TCM sets the OBDII code when the Transmission Fluid Pressure Sensor/Switch is not to factory specifications.
How to diagnose transmission pressure sensor Nissan p0840?
Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The bulletin suggests replacing the transmission valve body. What does this mean? The cost of diagnosing the P0840 NISSAN code is 1.0 hour of labor.
What does p084a stand for in OBD codes?
P084A 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 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.
