P083D - OBD Trouble Code

<<See All OBD Codes

Is your Check Engine Light illuminated on the car’s dashboard? Are you experiencing sudden drop in the fuel economy with stalling of the engine? Or is there any engine stalling and gear slipping? Then, there might be a possibility of an issue with the transmission control module and pressure sensor of the car thus indicating OBD Code P083D error.

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. For the Powertrain Control Module (PCM) or Transmission Control Module (TCM) the TFPS converts the mechanical transmission pressures into an electrical signal. The PCM/TCM informs other controllers utilizing the vehicle's data communication bus. The PCM/TCM receives this voltage signal to determine transmission operating pressure or when a shift is occurring. P083D is typically a TFPS sensor circuit issue, although as previously stated this code may also be set due to mechanical issues.

What causes this problem with the Transmission Fluid Pressure Sensor/Switch "G" Circuit High?

• Low transmission fluid level
• Dirty transmission fluid
• Transmission oil leak
• Transmission clutch problems
• Low oil pressure
• Transmission control module failure
• Transmission speed sensor failure
• TFPS circuit malfunction due to mechanical damages
• PCM failure
• TCM failure
• Corroded connections or pins and wring issue (corrosion, chafed, melted)

1. Engine Control Module - OBD Error Code P083D can also be due to faulty ECMs. It’s better to get the faulty electricals replaced as soon as possible.
2. Powertrain Control Module - Faulty PCM can easily distorted engine timing causing frequent halting. Find all the Powertrain related parts with us.
3. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
4. Automatic Transmission Control Module - Check for faulty TCM and components and replace it, if found so. Buy new TCM now!
5. Automatic Transmission Sensor - Transmission sensor plays a vital role in smooth transmission and gear shifts. Repair or replace faulty sensor and components now!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P083D code by mentioning some major symptoms below:

Common Symptoms

• Intermittent condition
• Lack of engine power
• Slow speeds
• Transmission slipping
• Transmission shifts erratic
• Harsh shifts

Have a look at some ways with which you can correct the P083D code:

• Shift solenoid replacement
• Powertrain control module replacement
• Transmission control module replacement
• Adding or replacing the transmission fluid and filter
• Overhauling the current transmission Installing a brand new transmission fluid pressure sensor

We are sure that now all your issues would be resolved.

Here are some steps which you should follow in order to diagnose this fault code:

• A qualified mechanic will need a digital volt ohm meter (DVOM) for the complete test. Continue through the tests until the problem is confirmed. You will also need a basic OBD code scanner to reset the computer and erase the code.
• Begin by checking the levels of the transmission oil. Visually inspect the transmission itself for damage. Inspect the vehicle housing for signs of cracks or damage. If there are any cracks that may or may not be leaking, the transmission should be replaced. Replace any damaged seals. Locate speed sensors on the transmission and inspect sensors and connectors for signs of damage. If any damage present, repair or replace.
• Inspect for optimal oil pressure. Using an oil pressure gauge, test the transmission oil pressure. Make sure to use the transmission pressure test port. Connect gauge to the test port and start vehicle. Ensure there are no leaks at connection.
• Check for faults in the speed sensors. Unplug the transmission speed sensors. Using multimeter, test the resistance values within the sensor. If values aren’t within specifications, replace sensors and clear codes.
• Identify wires involved in speed sensor circuits. Check for continuity, shorts and open in the wires involved which includes the ECM connector so make sure battery is disconnected before testing and repair the problem.
• Ensure the functioning of the TCM by testing the TCM by back probing the connector and measuring electrical values. Also check the connector and wiring to the TFPS looking for scraping, rubbing, bare wires, burn spots or melted plastic. Pull the connector apart and carefully inspect the terminals inside the connector.

Common Mistakes When Diagnosing the P083D Code

When diagnosing a P083D code the most common misdiagnosis would be to have the transmission replaced assuming that internal damage has occurred. It is important to note that the transmission is faulty before replacing it. It is best to make sure the transmission actually needs to be replaced before adding even more to the cost of repairs.
