Fault Codes / DTCs

This Technical Service Bulletin (TSB) specifically addresses the following diagnostic trouble code:

Diagnosis / Trigger Conditions

The primary cause for the Nissan Rogue DTC P2DFD, as identified by Nissan, is frequently an improperly fitted wire harness connector for the EVAP Canister Electric Purge Pump. This means the pump itself may not be faulty, but rather its electrical connection is loose or not fully engaged. Technicians are advised to first check this connection before proceeding with more extensive diagnostic procedures.

Repair Procedure Summary

Nissan TSB NTB22-066 outlines a straightforward procedure to address the Nissan Rogue DTC P2DFD:

1. Preparation: Begin by turning the vehicle's ignition OFF to ensure safety and prevent electrical issues.
2. Disconnect Connector: Locate the EVAP Canister Electric Pump wire harness connector, which is typically found under the intake tube (as shown in Figure 1 of the original bulletin). Carefully disconnect this connector.
3. Re-connect and Verify: Re-connect the EVAP Canister Electric Pump wire harness connector. It is crucial to ensure the connector is fully seated and that its lock tab is securely engaged. Figure 2 in the bulletin provides a visual guide for proper engagement of the lock tab.
4. Engine Run Cycle: Start the engine and allow it to run for a minimum of one minute. This allows the vehicle's systems to re-evaluate the EVAP system's performance.
5. DTC Re-check: After the engine run cycle, check if the DTC P2DFD is still detected.
   • If P2DFD is still present: The technician should then proceed with the detailed diagnostic procedure for DTC P2DFD in the Electronic Service Manual (ESM). This involves navigating through ENGINE > ENGINE CONTROL SYSTEM > KR15DDT > DTC/CIRCUIT DIAGNOSIS > P2DFD PURGE PUMP PERFORMANCE > DTC Diagnosis Procedure.
   • If P2DFD is no longer present: This indicates that the issue was caused by the improper fitment of the EVAP Canister Electric Pump wire harness connector, and no further diagnosis or repair is required for this specific fault.
