P083D Code:

OBD-II Diagnostic Powertrain (P) Trouble Code

Possible Cause

Common causes of P083D is include shorted, open, corroded, or damaged wiring circuits or connectors, faulty shift solenoid/s, defective engine drivability sensors (especially the engine temperature sensor), dirty or contaminated transmission fluid that restricts flow, defective valve body, a faulty PCM. PCM failure is rare.

Common Symptoms

  1. Corroded connectors, at or near the fuel shutoff valve, frequently test appropriately until the circuit is loaded, at which time the circuit is compromised due to excessive resistance
  2. Unlike other diagnostic codes, this type of code can sometimes be best left to a professional simply because of the bulk of circuitry involved
  3. This signal is systematically forwarded to affected control modules that utilize the data to accomplish various other tasks
  4. Typical causes of low pump pressure include clogged hydraulic passages, a defective pump, faulty shift solenoids, or a faulty electronic pressure regulator

P083D Troubleshooting

When you put your foot down on the brakes you expect your car to quietly slow down and come to a stop. The power your foot applies on the brake pedal is assisted by hydraulic pressure. Your foot's force engages a piston and caliper with brake pads attached (bonded abrasive and heat resistance metal or ceramic) to put pressure on the rotor. P083D OBD2 reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

How to turn off P083D check engine light ?

There are two ways to turn off the check engine light:

A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
