What is a transmission fluid pressure sensor switch?
A transmission oil pressure switch, also commonly known as a line pressure switch, is used on transmissions with hydraulic fluid under pressure. The switch will tell the computer to default the transmission into a gear with the least amount of pressure without any damage. This condition is known as limp mode.
What does a p0847 diagnostic trouble code mean?
A P0847 diagnostic trouble code is actually quite serious, because if there is a problem with either the transmission fluid pressure sensor, or the amount of hydraulic pressure available, a number of drivability issues can occur. These include harsh shifts, delayed shifts and transmission overheating.
What is p0847 Trans fluid pressure sensor switch B circuit low?
P0847 is typically an electrical circuit (TFPS sensor circuit) issue. This cannot be overlooked in the troubleshooting stage, especially when dealing with an intermittent problem. Troubleshooting steps may vary depending upon manufacturer, type of TFPS sensor and wire colors. Related trans fluid pressure sensor B circuit codes:
What is the diagnostic code for transmission fluid pressure?
P0847 is a diagnostic trouble code (DTC) for “Transmission Fluid Pressure Sensor/Switch “B” Circuit Low”.
How much does it cost to repair a Honda p0847?
The cost of diagnosing the P0847 HONDA 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. Most auto repair shops charge between $75 and $150 per hour.
What are the possible causes of the p0847 code?
P0847 Possible Causes 1 Faulty Transmission Fluid Pressure Sensor/Switch ‘B’ 2 Transmission Fluid Pressure Sensor/Switch ‘B’ harness is open or shorted 3 Transmission Fluid Pressure Sensor/Switch ‘B’ circuit poor electrical connection

What causes a transmission fluid pressure code of p0846?
The cause of a P0846 trouble code may lie with a faulty component relating to the transmission, most commonly the faulty electronic pressure control solenoid or transmission fluid pressure sensor itself. Low, decontaminated or dirty transmission fluid may be to blame as well.
