Hi all,
I got a P1402 error code on my 96 protege 1.5L.
From the manual, it is EGR Valve Position Sensor Open or Short.
I checked the connection between EGR Valve Position Sensor and the PCM. The snesor keeps giving +5V output. It looks like the EGR Valve was stuck in the Open position. And the following symptom can confirm this. The engine has a rugh idle and sometimes stalls before the red light.
However, someone says it may be the leak of the vacuum hose connect to the EGR valve. I am confused. As what I understand, the vacuum hose is used to open the valve. If it is leaking, the valve can't be opened, right? Please correct me!
I am planing to uninstall the EGR valve and clean it first. Is there any suggestion?
It is hard to reach the EGR valve. Besides the air intake hose, are there any other parts I need to remove before I can get the EGR valve?
Thanks a lot!
