What is the EGR valve on a Hyundai Santa Fe?
They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Hyundai Santa Fe or not).
Why does my Hyundai Santa Fe have insufficient flow?
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. This is especially true if you are experiencing P0401 right after doing some engine work.
What causes the p0401 code on a Hyundai Santa Fe?
Diagnosing what is causing the P0401 code in the Santa Fe 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.
When did Hyundai Santa Fe gas recirculation valve fail?
April 26, 2018 5:15 p. M. Outside temp 80 degrees, sunny . 19056 miles. Making a left turn and failed to accelerate. Very limited acceleration despite full tank of gas. After about 10 seconds of mashing accelerator to the floor, it finally picked up and took off.

What does the code p0401 on an EGR mean?
Code P0401 is triggered when the EGR temperature sensor does not see enough of a temperature change when the EGR is commanded to open. These sensors tend to get a lot of carbon buildup that causes them to lose sensitivity to the heat from the EGR gases. Need help with a P0401 code?
What are the symptoms of the p0401 OBD-II trouble code?
The EGR temperature sensor is not registering enough of a temperature change when the EGR valve is opened. The EGR passages are partly blocked and will not allow enough flow of exhaust gases into the intake manifold. What are the symptoms of the P0401 code? The Check Engine Light will be illuminated and the code is set in ECM memory.

What is the EGR code for insufficient flow?
The code relates to flow from the EGR to the intake. Remove EGR and throttlebody and clean the ports with intake cleaner and a scribe or snake. Also check for leaking gaskets or lines but usualy the system is just CLOGGED with hard carbon. Remove clog and flow will return and your light will not come back on. Loading…
