The P2402 code is related to the Evaporative Emission (EVAP) system. It indicates that the leak detection pump is stuck ON. The Engine Control Module (ECM) monitors the EVAP pressure for leaks and actuator malfunctions. The leak detection pump creates negative pressure in the EVAP system.
16 paź 2016 · Why are you mapping the analogue reading to 0-255? How are you changing the pressure to test the sensor output? Do you have a serial connection available? It might be easier to output the number to that rather than using it to blink an LED. Or better yet, just connect a multimeter to the sensor output.
26 cze 2023 · The EVAP system pressure sensor is responsible for measuring the pressure in the fuel tank and sending this information to the engine control module (ECM). If this sensor is faulty, it may send an incorrect signal to the ECM, triggering a P2402 code.
30 sie 2024 · How to Fix P2402 Toyota. Diagnose the specific cause of the issue using a scan tool. Inspect the Evaporative Emission Leak Detection Pump, purge valve, hoses, and connectors for any damage or leaks. Replace any faulty components identified during the inspection.
Code P2402 is an indication that the evaporative pump is shorted internally and other than failing emission tests and the check engine light being on, should not cause any drivability problems. What repairs can fix the P2402 code?
18 sie 2024 · Diagnose the issue using a scan tool to confirm the P2402 code and identify the specific component causing the problem. Inspect the Evaporative Emission Leak Detection Pump and associated components for any visible damage or leaks. Test the wiring and connections for proper voltage and continuity.
