Fix P2719: STEP-BY-STEP diagnostic GUIDE!

The P2719: Pressure Control Solenoid ‘D’ Control Circuit Range/Performance code indicates that the Transmission Control Module (TCM) has detected that pressure control solenoid ‘D’ is operating outside of its expected range. This could be due to a faulty solenoid, issues with the TCM, or wiring and connector problems. The solenoid is responsible for regulating hydraulic pressure in the transmission, and an out-of-range performance issue can lead to erratic shifting, slippage, or other transmission performance problems.

P2719 – Quick Overview

Code	Information
Meaning	P2719: Pressure Control Solenoid ‘D’ Control Circuit Range/Performance
Is it serious?	Yes, as an out-of-range solenoid can cause improper hydraulic pressure control, leading to rough shifting, slipping, or transmission overheating.
Possible causes	– Out-of-range performance of pressure control solenoid ‘D’ – Faulty solenoid or TCM – Wiring or connector issues
How to diagnose?	– Check the performance of pressure control solenoid ‘D’ – Inspect wiring and connectors – Verify control module functionality – Replace faulty components as needed

P2719 Meaning

The P2719: Pressure Control Solenoid ‘D’ Control Circuit Range/Performance code indicates that the pressure control solenoid ‘D’ is not operating within the expected parameters set by the manufacturer. This issue can be caused by problems with the solenoid itself, such as internal wear or damage, electrical issues such as faulty wiring or connectors, or a malfunctioning control module. Proper solenoid function is essential for maintaining correct hydraulic pressure, which is necessary for smooth and efficient transmission shifting.

Step-by-step diagnostic guide

Action	Description	Tools Needed
Check for Other Codes	Use an OBD-II scanner to determine if there are any additional related codes that might provide more insight into the transmission system or pressure control issues.	OBD-II Scanner
Test Pressure Control Solenoid ‘D’ Performance	Use a diagnostic scanner to check the operation of pressure control solenoid ‘D’. Look for any indications that the solenoid is operating outside of the expected range, such as inconsistent activation or slow response.	Diagnostic Scanner
Inspect Solenoid ‘D’ and Circuit	Locate and visually inspect pressure control solenoid ‘D’. Look for any physical damage or visible issues that could affect performance, such as contamination, blockages, or improper installation.	Flashlight, Safety Gloves
Check Wiring and Connectors	Inspect all wiring and connectors associated with pressure control solenoid ‘D’. Check for loose, corroded, or damaged connectors, and inspect wiring for frays, open circuits, or grounding issues that may be causing out-of-range performance.	Flashlight, Multimeter
Perform Voltage and Continuity Tests	Use a multimeter to verify the voltage supplied to pressure control solenoid ‘D’. Measure the voltage when the solenoid is activated by the TCM and compare it to the manufacturer’s specifications. Check for continuity to ensure there are no breaks in the wiring.	Multimeter
Verify Resistance of Solenoid ‘D’	Measure the resistance of pressure control solenoid ‘D’ using a multimeter. Compare the reading with the manufacturer’s specifications. An out-of-range reading can indicate internal damage or wear in the solenoid.	Multimeter
Inspect the Transmission Control Module (TCM)	Use a diagnostic tool to monitor the signals being sent to pressure control solenoid ‘D’. Ensure that the TCM is providing proper commands and that there are no unexpected drops or surges in output.	Diagnostic Scanner
Check Hydraulic Pressure	Verify that the hydraulic pressure in the transmission is consistent with the control signals from solenoid ‘D’. This test helps confirm whether the solenoid is regulating pressure properly or if there is an internal hydraulic issue causing out-of-range performance.	Hydraulic Pressure Gauge
Replace Faulty Components	If pressure control solenoid ‘D’ or any other component, such as wiring or connectors, is found to be faulty, replace them. Ensure that all replacements are in accordance with manufacturer specifications for proper operation.	Replacement Solenoid, Wiring
Clear the Code and Test System	After completing the repairs, use an OBD-II scanner to clear the P2719 code. Conduct a thorough test drive to ensure that the transmission shifts smoothly and that solenoid ‘D’ is operating within the correct parameters.	OBD-II Scanner, Vehicle Owner’s Manual
Recheck for Codes	Re-scan the vehicle to ensure that the P2719 code has not returned and that the transmission system, including pressure control solenoid ‘D’, is functioning correctly.	OBD-II Scanner
