an egr valve opens to put inert gases in the combustion chamber to lower the temperature. this is done to reduce NOx emissions that are produced at high temperatures.
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
take the EGR valve off and spray carb cleaner in the egr valve and in the port. This will some times work as it gets plugged up
Yes, the EGR valve, or port EGR
P0401 "egr insufficient flow" can indicate many things, including: 1-vacuum line plugged or leaking 2-pipe from exhaust to egr valve plugged 3-pipe to vacuum modulator valve from egr valve plugged 4-passages at egr are plugged 5-bad egr valve 6-bad EGR VACUUM MODULATOR VALVE I tried cleaning egr modulator valve, (beside/above egr)removed and tested egr vacuum & movement, inspected and cleaned all vacuum lines openings and pipes. All above did not work. I replaced the egr vacuum modulator valve. Light went out without a reset in about 30 miles of driving. Not sure if this valve can be cleaned. Retails for $69.US
The EGR valve and the EGR sensor work together. The EGR gas temperature sensor is mounted near the EGR valve. The sensor detects the temperature of the exhaust as it moves through the valve. The information is sent to the ECM and in turn the EGR on/off time is regulated precisely and more efficiently. Any malfunction with the EGR gas temperature sensor will set off a code 35 ( Info taken from HAYNES MANUAL)
It doesn't have an egr valve.
As I recall, that engine does not have an EGR valve.
There is no EGR valve on an Aspire.
There is NOT an EGR valve on this engine.
does a Hyundai tiburon have a egr valve
On the egr valve.
The PCM controls the EGR valve, so the EGR position sensor tells the PCM what position the EGR valve is in, so it can control the EGR valve and ake other necessary adjustments.
