How severe is this DTC?
The severity of this code is generally not severe, as it will likely only affect the PTO functions, but not the normal functions of the vehicle.
What are some of the symptoms of the code?
Symptoms of a P253E fault code may include:
Power take-off auxiliary equipment will not operate
Check engine light illuminated
What are some common causes of the code?
Causes
of this P253E code may include:
- Faulty PTO sensor
- Defective or damaged wiring
- Corroded, damaged, or loose connector
- Faulty fuse or fusible link (if applicable)
- Faulty PCM
What are the troubleshooting steps for P253E?
The first step in the troubleshooting process for any malfunction is to search for Technical Service Bulletins (TSBs) for the specific vehicle by year, model, and engine/transmission configuration. In some circumstances, this can save you significant time in the long run by pointing you in the right direction.
The second step is to locate all components associated with the power take-off circuit and look for obvious physical damage. Perform a thorough visual inspection to check that the associated wiring does not have obvious defects such as scraping, rubbing, exposed wires, or burns. Then, check connectors and connections for security, corrosion, and damaged pins. This process should include all wiring connectors and connections to all components, including the PCM. Consult vehicle-specific technical data to verify the oil level safety circuit configuration and see if a fuse or fusible link is incorporated into the circuit.
Advanced Steps
Advanced steps become very vehicle-specific and require appropriate advanced equipment to function accurately. These procedures require a digital multimeter and vehicle-specific technical references. In this situation, an oil pressure gauge may facilitate the troubleshooting process.
