The P2736: Pressure Control Solenoid ‘F’ Control Circuit/Open refers to an issue where the control circuit for pressure control solenoid ‘F’ is either open or disconnected. This can be caused by faulty wiring, a defective solenoid, or control module problems. When the circuit is open, the transmission may be unable to properly regulate hydraulic pressure.
P2736 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2736: Pressure Control Solenoid ‘F’ Control Circuit/Open |
| Is it serious? | Yes, an open circuit can prevent the solenoid from functioning, causing transmission problems and improper shifting, potentially leading to vehicle drivability issues. |
| Possible causes | – Open circuit or disconnected wiring in pressure control solenoid ‘F’ – Faulty solenoid or connector – Control module issues |
| How to diagnose? | – Inspect and test pressure control solenoid ‘F’ control circuit – Check for open circuits and disconnected wiring – Verify solenoid and connector integrity – Replace damaged components as needed |
P2736 Meaning
The P2736: Pressure Control Solenoid ‘F’ Control Circuit/Open code indicates that there is an open or disconnected circuit in the control wiring for pressure control solenoid ‘F’. This open circuit means that the solenoid is not receiving the necessary signals from the control module to operate properly, which can lead to issues in transmission fluid regulation and shifting.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that might help identify additional issues contributing to the open circuit condition. | OBD-II Scanner |
| Inspect Pressure Control Solenoid ‘F’ and Wiring | Visually inspect the solenoid and its wiring for any obvious signs of damage, disconnected wiring, or broken connectors. | Flashlight, Safety Gloves |
| Test Pressure Control Solenoid ‘F’ Control Circuit | Use a multimeter to check for continuity in the control circuit. An open circuit will show no continuity, indicating a broken or disconnected wire. | Multimeter |
| Check for Open Circuits and Disconnected Wiring | Carefully inspect all wiring leading to the solenoid for disconnections, broken wires, or signs of corrosion. Pay special attention to areas where wires may be rubbing or pinched. | Multimeter, Flashlight |
| Verify Solenoid and Connector Integrity | Ensure that solenoid ‘F’ and all connectors are in good condition. A faulty or corroded connector can lead to an open circuit. Replace any damaged components as needed. | Diagnostic Tool, Replacement Connectors |
| Test Control Module Signal | Verify that the control module is sending the proper signals to the solenoid. If no signal is present, the control module may be faulty. | Diagnostic Tool, Manufacturer Software |
| Replace Damaged Components as Needed | Replace any faulty or damaged parts, including the solenoid, wiring, connectors, or control module if it is not functioning correctly. | Replacement Solenoid, Wiring Repair Kit |
| Clear the Code and Test Drive | After repairs, use an OBD-II scanner to clear the P2736 code, then take the vehicle for a test drive to ensure the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | Perform a final scan after the test drive to verify that the P2736 code has not returned. If it reappears, further diagnosis may be needed. | OBD-II Scanner |
