What is code P2402 means?
OBD Code P2402 – Evaporative Emission System Leak Detection Pump Control Circuit High. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. OBD code P2402 means Evaporative Emission System Leak Detection Pump Control Circuit High.
What does the OBD code p2402 stand for?
OBD-II Code P2402 is defined as a Evaporative Emission System Leak Detection Pump Control Circuit The Leak Detection Pump is part of the Evaporative Emissions System. After the vehicle has been sitting for a few hours, this pump will turn on and create a vacuum in the EVAP system. The engine computer (PCM) runs this test when the vehicle is off.
What does the trouble code p2401 mean on EVAP?
The P2401 trouble code is telling us the EVAP control circuit has had a fault with the leak detection pump. The leak detection pump is used by the ECM to pressurize the EVAP system to check for leaks that are present. When the ECM has detected the the circuit has low voltage it will trigger a P2401 code.
What is the OBD code for the EVAP leak detection pump?
P2402 is an OBD-II generic code for the engine control module (ECM) detecting the evaporative system leak detection pump control circuit has a high voltage signal return.
When does the PCM set the code p2402?
If the PCM does not see the Leak Detection Pump activate as requested, or does not see a vacuum created in the EVAP System, the PCM will set code P2402.
OBD-II Code P2402 is defined as a Evaporative Emission System Leak Detection Pump Control Circuit The Leak Detection Pump is part of the Evaporative Emissions System. After the vehicle has been sitting for a few hours, this pump will turn on and create a vacuum in the EVAP system. The engine computer (PCM) runs this test when the vehicle is off.
What does the code p2402 on an evaporative pump mean?
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? Replace the evaporative pump and fuse. Replace the evaporative pump relay.
P2402 is an OBD-II generic code for the engine control module (ECM) detecting the evaporative system leak detection pump control circuit has a high voltage signal return.
If the PCM does not see the Leak Detection Pump activate as requested, or does not see a vacuum created in the EVAP System, the PCM will set code P2402.
What does the p2402 code on an engine mean?
What the P2402 code means? P2402 is an OBD-II generic code for the engine control module (ECM) detecting the evaporative system leak detection pump control circuit has a high voltage signal return. What causes the P2402 code? The ECM monitors the EVAP control system pump current and if the current goes higher than specified then the code is set.
