Why does my Honda Odyssey have insufficient flow?
In some 1999–2003 Honda Odysseys and 2003 Honda Pilots, the EGR system may become contaminated or clogged. If this happens, the vehicle may hesitate or surge during light acceleration, and the MIL (malfunction indicator lamp) may come on with DTC P0401 (EGR insufficient flow) or P1491 (EGR valve insufficient lift).
What causes the p0401 code on a Honda Odyssey?
Diagnosing what is causing the P0401 code in the Odyssey is typically not very tricky. Here are the most common causes: Blocked EGR Tube – The tube that carries the exhaust gases back to the motor may clog up over time. Alternatively, it can become bent or kinked.
What is the EGR system on a Honda Odyssey?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the Odyssey’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
What to do if your Honda Accord p0401 has insufficient flow?
Check the EGR Tube- It’s a good idea to check the tube going to the EGR because it’s often the cause of P0401, easy to do, fast, and replacing it is very afHondaable. If it’s cracked, you’ll need to get a new one. If it’s clogged you can get away with cleaning it and replacing it.
What does p0401 EGR insufficient flow detected mean?
If you own a Honda and encounter a P0401 egr insufficient flow detected, follow these instructions. The P0401 code is defined as Exhaust Gas Recirculation Flow Insufficient Detected. The computer commands the EGR valve to open. An EGR position sensor is built into the valve to detect how much the valve actually opened.
