P0990 BUICK code

The P0990 code is a generic powertrain code related to the transmission, including pressure faults and sensor failures. In this case, the transmission control module has received a higher than normal voltage signal from the transmission fluid pressure sensor/switch E.

What does P0848 code mean?

P0848 code definition

The storage of a P0848 trouble code means that the powertrain control module (PCM) has detected a problem with the transmission fluid sensor circuit. The pressure to the hydraulic pump is controlled by the PCM via the electronic pressure control solenoids.

What does P083B code mean?

When the TCM detects an incorrect signal from the Transmission Pressure Sensor, it sends a signal to the engine control module (PCM) to set code P083B. Driving with this trouble code is not recommended. A vehicle with this code should be taken in to a repair shop for diagnosis.

What is code P0989?

The P0989 code is a generic OBD-II trouble code that detects a transmission fluid pressure sensor E circuit abnormality. In this case the “E” circuit is a region of the circuit, and not any one component. This sensor circuit is a key component of the transmission hydraulic pressure system.

Where is the transmission fluid pressure sensor?

The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.

What is code P0847?

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.

How do I fix code P083B?

How to Correct P083B Transmission Fluid Pressure Sensor/Switch “G” Circuit Range/Performance

  1. Checking for transmission fluid or changing the transmission fluid.
  2. Defective shift solenoid replacement.
  3. Replacing or reprogramming Transmission Control Module.
  4. TFPS circuit repair and replacement.

How do you change a transmission pressure switch?

Zitat von Youtube: So you have space to move new for this section so you're gonna use a 10 millimeter bolt i mean a bolt a socket to remove this and then a 10 millimeter wrench down there to remove.

What does transmission fluid pressure low mean?

If the fluid is low, it should be assumed that there is a leak in the system, and the mechanic should begin searching for where the leak is coming from. Depending on the location of the leak, it may be able to be repaired, and the issue resolved.
