Error Code P083E: What It Means & What To Do?

<<See All OBD Codes

Are you experiencing hard gear shifts and gear slipping in fourth gear? Is there a lack of engine power and hesitation during acceleration? Is the Check Engine Light illuminating on dashboard? All these may be due to heat up problems with the transmission fluid sensor flashing and storing OBD code P083E in the Powertrain Control Module (PCM).

OBD-II Code Transmission may not shift properly is defined as a Transmission Fluid Pressure Sensor/Switch "G" Circuit Intermittent. The Transmission Fluid Pressure Sensor informs the Transmission control module (TCM) about the pressure of the fluid going through the transmission. 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 P083E.

Since this could be an electrical failure or a mechanical failure, the PCM/TCM can compensate to some degree since the severity of this error code depends upon which circuit the failure has occurred in. The failure may mean that the PCM/TCM modifies the shifting of the transmission if electronically controlled.

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

• Faulty gear related shift solenoid
• Faulty gear related gear set or clutch pack
• Engine Coolant Temperature Sensor faulty
• Defective Valve Body
• Faulty Transmission Control Module due to mechanical failure
• Transmission Fluid Pressure Sensor failure
• Dirty transmission fluid that restricts the hydraulic passages

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P083E code by listing out some major symptoms. They are mentioned below as follows

Common Symptoms

• Check Engine Light will illuminate
• Vehicle will not shift properly
• Decrease in fuel economy
• Transmission Slipping

Learn the ways with which you can correct this trouble code:

• If the transmission has suffered damage due to a low fluid condition, first rebuild the transmission, perform a fluid flush, and replace the torque converter
• Check the wiring or connectors and replace any damaged, or faulty, wiring or connectors
• Repair any leaks if the transmission fluid looks like it is in good condition and is only low
• Replace the Transmission Control Module if this component is damaged
• Transmission Fluid Pressure Sensor replacement
• Repair or replace any damaged circuits or connectors
• Replace the shift solenoid, or solenoid pack if faulty
• Replace the PCM, if found faulty

However, if you face any issue then we have stocked a wide range of best priced Transmission control module, Digital voltmeter, Powertrain control module, Transmission fluid pressure sensor, Automatic transmission module, PCM, ECM and more to help you out in fixing your car.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P083E code to be stored:

• Visually inspect all wiring, connectors, and components associated with the transmission system. They should look for any loose, damaged, or corroded wiring, components, or connectors, replacing them if needed.
• Save the freeze frame data and any stored trouble codes on the PCM using the scanner. Clear any codes and test drive the vehicle to see if the codes return. If the code returns, check the individual auto transmission connector to see if a reference voltage or ground signal are present.
• Check the transmission fluid level and condition and lookout for a burnt or abnormal smell, which can indicate that the transmission has suffered damage from a low fluid condition. If this is the case, the mechanic should remove the transmission pan and inspect it for pieces of the clutch or other debris.
• If the transmission fluid is low, fill the transmission fluid to a point that any leaks can be detected and repaired. Once all leaks are found and fixed, the transmission fluid must be filled to an appropriate level.
• Clear the code, allow the vehicle to reach a normal operating temperature, and test drive the vehicle to see if the trouble code returns.
• If the code returns and the transmission is still slipping or hesitating, the mechanic should connect a manual pressure gauge. Using the manual pressure gauge in conjunction with a hydraulic pressure diagram, they should check the pressure of the transmission hydraulic pump. The mechanic should compare their findings to manufacturer specifications.
• Use a manufacturer's wiring diagram to test Transmission Fluid Pressure Sensor circuits for resistance and continuity, comparing their findings to the manufacturer's specifications. If everything checks out and is in good condition, the next step is to diagnose the PCM for failure.
• Finally, once all repairs are made, clear the code and retest the system to see if the trouble code returns.

Common Mistakes When Diagnosing the P083E Code

Some of the common mistakes done while changing diagnosing the OBD code P083E are:

• Engine Misfire problem
• TCM/PCM failure
• TFPS problematic
• Internal Transmission problem
• Driveline problem
