P255C - OBD Trouble Code

<<See All OBD Codes

When a P225C trouble code sets it means that the Powertrain Control Module has detected a fault, specifically low voltage, on the PTO speed selector sensor/switch 2.Power take-off (PTO) transfers the mechanical power of the engine over to another piece of the equipment. This allows for the power to move throughout the equipment to transmit energy even if it doesn’t have a motor or engine itself. The speed sensor determines the optimal working speed of the PTO system and the OBD code P255C gets stored when the speed sensor has low voltage output.

The power take-off may be engaged by means of a cable, lever, air pressure, or hydraulic pressure. The latest PTO shifting design incorporates a small electric motor and hydraulic pump within the shift cover assembly to provide hydraulic force to engage the PTO. Various output shaft configurations are available to allow for a driveshaft connection or the attachment of hydraulic pumps directly to the PTO without an intermediate shaft.

What causes this problem with PTO Speed Selector Sensor/Switch 2 Circuit Low?

• Problematic PTO speed selector sensor
• PTO sensor circuit wiring and connector issue
• Damaged hydraulic pump and shaft system
• PTO speed switch faulty
• Powertrain control module error

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is the in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
3. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
4. Diagnostic Tools - Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!
5. Automatic Transmission Sensor - Automatic transmission sensor transmits correct information for the TCM to make various decision including gear shift and ensuring smooth drive in coordination with the engine. Thus, replace faulty components now!
6. PTO Speed Selector Sensor - Check for the faults in the speed sensor that may affect the PTO system functionality and thus might need replacement.

If you are facing OBD error code P255C then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Check Engine Light illuminated (Malfunction indicator lamp)
• Delayed shift or not shifting into gears
• Transmission slipping
• Hydraulic or shaft system non-responsive

Wish to correct this error code with your vehicle? Do you know what all you should do to make your car free from this code? Well, don’t worry! We are here to guide you.

• Refill of Low transmission fluid level

Apart from this, you might need to replace other damaged parts too like PCM, PTO Speed Selector Sensor, PTO Speed Selector Switch, Transmission, PTO sense circuit, Engine Light, Oil Pressure Gauge and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• A mechanic will first input an OBD-II code reader into the vehicle's computer in order to read and identify the trouble code.
• Feed a hydraulic pressure diagram into the proper opening in the transmission system in order to take pressure readings directly from the source.
• Test the transmission fluid with a dipstick and checked for problems. Compare any diagnostic findings with the car manufacturer's default specifications in order to pinpoint abnormalities.
• If there are other trouble codes registered on the OBD-II reader, it may offer additional guidance in finding the root problem.
• Check for scraping, rubbing, bare wires, burn spots or melted plastic in the PTO sensor and circuit and urns and corrosions over the connector terminal and make use of electrical contact cleaner to clean them.
• Before replacing the sensor, it is important to check for the reference voltage to the sensor and the module in on and off condition, if accordance to the appropriate range as per the car’s specification.
• Always check for PMC faults and repair, replace or reprogram as required.

Common Mistakes When Diagnosing the P255C Code

Oftentimes the PCM sensor and circuit is blamed, and replaced, without checking the circuit as well as neglecting the damaged wiring and connectors. Because there can be several causes for this code, a complete inspection should be carried out in order to avoid repairs that may be unnecessary and more expensive.

• Transmission Control Module (TCM) failure
• Transmission fluid level is low
• PTO speed selector sensor failure
• Wiring and connector issue
