How do I fix code P0847?
What repairs can fix the P0847 code?
- Replacement of electrical components in the transmission system.
- Replacement or addition of transmission fluid.
- Fixing of hydraulic blockages in the transmission system.
- Electronic pressure control solenoid replacement.
- Electronic pressure regulator replacement.
What does P0847 mean?
transmission fluid pressure
What the P0847 code means. The P0847 code is a standard OBD-II trouble code that detects a problem with the transmission fluid pressure “B” circuit. The “B” represents an area of the transmission fluid pressure circuit, rather than an individual component.
Why is the p0847 transmission fluid pressure sensor important?
The P0847 DTC means that there is a low voltage situation on the circuit that the transmission fluid pressure sensor operates on. The sensor is important to the operation of the transmission, because it relays the amount of hydraulic pressure available to the ECU. Need a replacement transmission?
What causes a p0847 OBDII trouble code?
Having dirty transmission fluid or a low level of transmission can actually cause a P0847 OBDII trouble code. If the ATF is clean and bright, then the wiring and connectors on the wiring harness will need to be checked, along with the operation of the transmission fluid pressure sensor itself.
What happens if the Allison transmission fault code is active?
If the code is active, then the retarder is prohibited. High signal from the current gear sensor. PS voltage sensor low voltage 1. Pressure Sensor High Voltage PS 1. The voltage at the control unit is below normal. Remains in the selected gear, monitors the signal for changing the direction of movement.
When does DTC p0847 set diesel place?
DTC P0847 sets when D solenoid is commanded OFF and pressure switch D status remains ON for 2-16 seconds, depending on fluid temperature. Inspect the wiring for poor electrical connections at the TCM. Inspect for the following conditions:
