How to diagnose p0841 Nissan transmission fluid pressure sensor?
Check 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. How much do you know about cars? The cost of diagnosing the P0841 NISSAN code is 1.0 hour of labor.
What should the target secondary pressure be on a Nissan Sentra?
GND short diagnosis of the solenoid valve circuit is not satisfied. After the value of “Actual secondary pressure − Target secondary pressure” exceeds 0.675 MPa: The rate of change in vehicle speed [km/h (MPH)]: Between −49 (−30) and +49 (+30) inclusive
How does transmission fluid pressure affect transmission shift quality?
The TFP directly affects transmission shift quality. Some transmissions will have multiple transmission fluid sensors. The TFP is a type of sensor called a transducer, which changes internal resistance relative to pressure. The powertrain control module (PCM) sends a reference voltage (typically 5 volts) to the sensor.
How to change transmission fluid in Nissan Sentra?
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test. >> GO TO 2. Start the engine. Shift the selector lever to “D” position.
Where is the pressure switch on a transmission?
The pump pressure switch is located on the transmission housing next to the pump. The switch lets the computer know what the pressure is coming from the pump when the engine is running. The servo pressure switch is located on the housing near a band or servo in the transmission.

How do I disable the transmission oil pressure switch?
Open the vehicle’s hood and disconnect the car’s battery. Take the ground cable off the battery’s negative post to disable the power going to the transmission oil pressure switch. Disabling the engine starting source prevents any fluid leaking under pressure. Note: It is important to protect your hands.
