P273A OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P273A can be explained as Transmission Friction Element "G" Apply Time Range/Performance. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

If the hybrid control module would detect a variation in the proper functioning of the transmission clutch that is outside the parameters set by the automobile manufacturer, then it would store the P273A error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Transmission Friction Element "G" Apply Time Range/Performance?

• The overall tire air pressure might be low
• Malfunctioning steering gear bellows boot
• Polluted gear/rack
• Some issues related to the inner tie rods
• There can be distorted steering gear

1. Automatic Transmission Module – Sometimes the transmission module is unable to communicate or correctly anticipate the speed of the vehicle and thus creates difficulty in gear shift leading to sluggish acceleration, throttle response and stalling. Thus can also hamper a lot of components physically and thus must be checked and replaced, if required.
2. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
3. Transmission Fluid Pump - If the transmission fluid pump fails, the fluid of the pump will not be able to circulate in the transmission and the driver may smell the fuel burning. Thus it might need immediate replacement.
4. Power Relay - Damaged power relay will affect the pump circuit and thus hamper the performance of the transmission fluid pump going from delays response to not working at all. Thus, replace it now!
5. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
6. Hybrid Battery - Faulty hybrid battery may overheat or discharge quickly, causing drivability issues. It can affect the acceleration and throttle response and can also cause damage to various parts. Replace the faulty hybrid battery now!
7. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P273A code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the transmission clutch itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P273A code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every component of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the transmission fluid level as well.
• If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P273A Code

• Malfunctioning transmission valve body solenoid
• There can be a failure in the internal transmission
• The level of the transmission fluid might be very low
• Wiring problems
