Guide To P273B OBD Error Code Solutions

<<See All OBD Codes

The trouble code P273B can be defined as Transmission Friction Element "H" Apply Time Range/Performance. It is the Power Steering Control Module (PSCM) which would examine the amount of force required to assist with vehicle steering when the ignition is ON and the voltage supply to the PSCM is above 6 volts, all other Electric Power-Assisted Steering (EPAS) sensors are working in the right manner and the EPAS gear is providing assist.

The proper operation of the transmission clutch is being monitored by the hybrid control module. This trouble code would be set by the hybrid control module when the functioning of the transmission clutch would not be as per the specifications set by the manufacturer.

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

• There might be less tire air pressure
• Unusable steering gear bellows boot
• Adulterated gear/rack
• Problems related to the inner tie rods
• Internal failure in the steering gear

1. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
2. Hybrid Battery - The hybrid battery is the heart of the drive motor and all the vehicle functions depend on it. Thus, if the battery is not charging, overcharging or discharging, it must be replaced to avoid any further damage to various parts of the car.
3. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
4. Transmission Fluid Pump - The first indication of any transmission related problem will the illumination Check Engine Light. Other major symptoms indicating bad transmission fluid pump can be bad shifts, delayed response and fuel burning smell coming from under the hood. Thus, immediate replacement is advisable.
5. 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!
6. Automatic Transmission Module – A defective transmission module will affect the gear shift mechanism and also affected during acceleration and deceleration. This will lead to affected engine performance and fuel delivery system. Thus, replace faulty transmission module now!
7. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
   
8. Diagnostic Tools - It is always advisable to use the correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in an efficient manner. Buy new quality diagnostic tools from us today!

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

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged transmission clutch and its components for error. It the mechanic finds the fault in the connectors as well as transmission fluid, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• Parts or components should not be replaced with reference to only a P273B DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P273B Code

• Non performance of the internal transmission
• Failure in the car wiring
• There can be low level of transmission fluid
• The transmission valve body solenoid might not function properly
