Code P253D 2017 GMC Sierra Description
The P253D diagnostic trouble code (DTC) for a 2017 GMC Sierra refers to the Power Take-Off (PTO) Relay Feedback Circuit High Voltage. This code indicates that there is a high voltage condition detected in the feedback circuit of the PTO relay. The PTO system in a vehicle is responsible for transferring power from the engine to auxiliary equipment, such as snowplows, tow trucks, or hydraulic systems. When this code is triggered, it can affect the performance of the PTO system and potentially lead to issues with the vehicle's functionality.
Common Causes of P253D 2017 GMC Sierra
- Faulty PTO relay.
- Wiring issues in the feedback circuit.
- Corrosion or poor connections in the electrical system.
- High voltage spikes in the system.
- Issues with the PTO control module.
Symptoms of P253D 2017 GMC Sierra
- PTO system not engaging or disengaging properly.
- Loss of power to auxiliary equipment.
- Illumination of the Check Engine Light.
- Decreased fuel efficiency.
- Vehicle stalling or hesitation during operation.
How to Fix P253D 2017 GMC Sierra
- Begin by conducting a thorough inspection of the PTO relay and feedback circuit to identify any visible damage or loose connections.
- Test the PTO relay using a multimeter to check for proper functionality and voltage levels.
- Inspect the wiring harness for any signs of damage, corrosion, or poor connections, and repair or replace as needed.
- Clear the DTC from the vehicle's computer using a diagnostic scanner and monitor the system for any reoccurrence of the code.
- If the issue persists, consider replacing the PTO relay or consulting a professional technician for further diagnosis and repair.

Frequently Asked Questions about P253D 2017 GMC Sierra Code
1. What does the OBDII code P253D mean on a 2017 GMC Sierra?
P253D indicates a problem with the Power Take-Off (PTO) Relay Feedback Circuit, specifically that the voltage is higher than expected.
2. What are the common symptoms of the P253D code?
Symptoms may include the check engine light turning on, PTO not functioning properly, or issues when operating auxiliary equipment connected to the PTO system.
3. What causes the P253D code to appear?
Common causes include a faulty PTO relay, damaged wiring or connectors in the feedback circuit, or a malfunctioning power control module (PCM).
4. Can I drive my 2017 GMC Sierra with the P253D code?
While the truck may still be drivable, the PTO system may not function correctly, which could impact auxiliary equipment. It's best to address the issue promptly.
5. How do you diagnose the P253D code?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the relay and wiring, and testing the PTO relay and circuit for voltage irregularities.
6. How can I fix the P253D code?
Repairs may include replacing the PTO relay, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.
7. Is the P253D code related to the PCM?
Yes, the PCM monitors the PTO relay feedback circuit and may trigger the code if it detects high voltage in the circuit.
8. How much does it cost to repair the P253D code issue?
Repair costs can vary but typically range from $100 to $300, depending on whether the issue is with the relay, wiring, or PCM.
9. What tools are needed to fix the P253D code?
You’ll need an OBDII scanner, a multimeter to check voltage, and basic tools for inspecting and replacing relays or wiring.
10. Can I clear the P253D code without fixing the problem?
Clearing the code without addressing the root cause will likely result in the code returning. Proper diagnosis and repair are necessary.
